Chapter 1. Overview

- Overview

Overview

The Cisco Nexus 9364D-GX2A switch (N9K-C9364D-GX2A) is a 2-rack unit (RU), fixed-port switch designed for deployment in data centers.

This switch includes these ports:

- 400-Gigabit QSFP-DD ports (64)

- 10-Gigabit SFP+ ports (2)

- Management ports (one RJ-45 port and one SFP port)

- Console port

- USB port

Note

Use dust covers (NXA-ACC-QDD-DC) for unused ports. This protects the connectors and helps divert airflow for thermal dispensation.

This switch includes these user-replaceable components:

- Fan modules (four) with these airflow choices:

- Port-side intake fan module with burgundy coloring (NXA-FAN-160CFM2-PI)

Note

If a fan fails, the other fans are automatically increased to 100% capacity to compensate. If two fans fail, then multi-fan failure policy kicks in, the switch will issue a warning, and power down in 2 minutes.

- Power supply modules (two—One for operations and one for redundancy [1+1]) with these choices:

- 3200-W port-side intake AC/HVDC power supply with burgundy coloring (NXA-PAC-3200W-PI)

- 3200-W port-side intake DC/HVDC power supply with burgundy coloring (NXA-PDC-3200W-PI)

Note

Both power supplies are the same type. Do not mix AC and DC power supplies.

Grounding pad

The fan and power supply modules are field replaceable. You can replace one fan module or one power supply module during operations, as long as the other modules are installed and operating. If you have only one power supply installed, you can install the replacement power supply in the open slot before removing the original power supply.

Note

All fan and power supply modules must have the same direction of airflow, or the switch can overheat and shut down. If you are installing a dual-direction power supply, that module automatically uses the same airflow direction as the other modules in the switch.

Caution

The switch has port-side intake airflow (burgundy coloring for fan modules), so you must locate the ports in the cold aisle. If you locate the air intake in a hot aisle, the switch can overheat and shut down.

Chapter 2. Preparing the Site

- Temperature Requirements

- Humidity Requirements

- Altitude Requirements

- Dust and Particulate Requirements

- Minimizing Electromagnetic and Radio Frequency Interference

- Shock and Vibration Requirements

- Grounding Requirements

- Planning for Power Requirements

- Airflow Requirements

- Rack and Cabinet Requirements

- Clearance Requirements

Temperature Requirements

The operating temperature of the switch is 32 to 104 degrees Fahrenheit (0 to 40 degrees Celsius). The non-operating temperature of the switch is –40 to 158 degrees Fahrenheit (–40 to 70 degrees Celsius).

Humidity Requirements

Climate-controlled buldings usually maintain an acceptable level of humidity for the switch equipment. If the switch is located in an unusually humid location, use a dehumidifier to maintain the humidity within an acceptable range.

Altitude Requirements

Altitude rating is 10,000 ft (3048 m). For China, it is 6,562 ft (2000 m).

Dust and Particulate Requirements

Exhaust fans cool power supplies. System fans cool switches by drawing in air and exhausting air out through various openings in the chassis. Fans also introduce dust and other particles, causing contaminant buildup in the switch and increased internal chassis temperature. Dust and particles can act as insulators and interfere with the mechanical components in the switch. Keep a clean operating environment to reduce the negative effects of dust and other particles.

In addition to keeping your environment free of dust and particles, use these precautions to avoid contamination of your switch:

- Do not smoke near the switch.

- Do not eat or drink near the switch.

Minimizing Electromagnetic and Radio Frequency Interference

Electromagnetic interference (EMI) and radio frequency interference (RFI) from the switch can adversely affect other devices, such as radio and television (TV) receivers. Radio frequencies that emanate from the switch can also interfere with cordless and low-power telephones. Conversely, RFI from high-power telephones can cause spurious characters to appear on the switch monitor.

RFI is defined as any EMI with a frequency above 10 kHz. This type of interference can travel from the switch to other devices through the power cable and power source or through the air as transmitted radio waves. The Federal Communications Commission (FCC) publishes specific regulations to limit the amount of EMI and RFI that are emitted by computing equipment. Each switch meets these FCC regulations.

To reduce the possibility of EMI and RFI, use these guidelines:

- Cover all open expansion slots with a blank filler plate.

- Always use shielded cables with metal connector shells for attaching peripherals to the switch.

When wires are run for any significant distance in an electromagnetic field, interference can occur to the signals on the wires with these implications:

- Bad wiring can result in radio interference emanating from the plant wiring.

- Strong EMI, especially when it is caused by lightning or radio transmitters, can destroy the signal drivers and receivers in the chassis and even create an electrical hazard by conducting power surges through lines into equipment.

Note

To predict and prevent strong EMI, consult experts in radio frequency interference (RFI).

The wiring is unlikely to emit radio interference if you use a twisted-pair cable with a good distribution of grounding conductors. If you exceed the recommended distances, use a high-quality twisted-pair cable with one ground conductor for each data signal, when applicable.

Caution

If the wires exceed the recommended distances, or if wires pass between buildings, give special consideration to the effect of a lightning strike in your vicinity. The electromagnetic pulse that is caused by lightning or other high-energy phenomena can easily couple enough energy into unshielded conductors to destroy electronic switches. Consult experts in electrical surge suppression and shielding if you have had similar problems in the past.

Shock and Vibration Requirements

The switch has been shock- and vibration-tested for operating ranges, handling, and earthquake standards.

Grounding Requirements

The switch is sensitive to variations in voltage that is supplied by the power sources. Overvoltage, undervoltage, and transients (spikes) can erase data from memory or cause components to fail. To protect against these types of problems, ensure that there is an earth-ground connection for the switch. Connect the grounding pad on the switch either directly to the earth-ground connection or to a fully bonded and grounded rack.

When the chassis is properly installed in a grounded rack, the switch is grounded because it has a metal-to-metal (no paint, stain, dirt, or anything else on it) connection to the rack. Alternatively, ground the chassis by using a customer-supplied grounding cable that meets your local and national installation requirements. For U.S. installations, we recommend 6-AWG wire. Connect your grounding cable to the chassis with a grounding lug (provided in the switch accessory kit) and to the facility ground.

Note

Create an electrical conducting path between the product chassis and the metal surface of the enclosure, or rack in which it is mounted, or to a grounding conductor. Provide electrical continuity by using thread-forming type mounting screws that remove any paint or non-conductive coatings and establish a metal-to-metal contact. Remove any paint or other non-conductive coatings on the surfaces between the mounting hardware and the enclosure or rack. Clean the surfaces and apply an antioxidant before installation.

Planning for Power Requirements

The switch includes two power supplies (1-to-1 redundancy with current sharing) in one of these combinations:

- Two 3200-W AC/HVDC power supplies

- Two 3200-W DC/HVDC power supplies

Note

For 1+1 redundancy, you must use two power sources and connect each power supply to a separate power source.

Note

Some of the power supply modules have rating capabilities that exceed the switch requirements. When calculating your power requirements, use the switch requirements to determine the amount of power that is required for the power supplies.

To minimize the possibility of circuit failure, verify that each power-source circuit that is used by the switch is dedicated to the switch.

Note

This Warning applies to DC input application.

Warning

Statement 1033—Safety Extra-Low Voltage (SELV)—IEC 60950/ES1–IEC 62368 DC Power Supply

To reduce the risk of electric shock, connect the unit to a DC power source that complies with the SELV requirements in IEC 60950-based safety standards or ES1 and PS1 requirements in IEC 62368-based safety standards or to a Class 2 power supply.

Note

We recommend 8-AWG wire for DC installations in the U.S.

Airflow Requirements

The switch is positioned with its ports in either the front or the rear of the rack, depending on your cabling and maintenance requirements. To identify the airflow options for your switch, see the user-replaceable components in the Overview section of this document. Position the fan and power supply modules to move the coolant air from the cold aisle to the hot aisle in one of these ways:

- Port-side exhaust airflow—Cool air enters the chassis through the fan and power supply modules in the cold aisle and exhausts through the port end of the chassis in the hot aisle.

- Port-side intake airflow—Cool air enters the chassis through the port end in the cold aisle and exhausts through the fan and power supply modules in the hot aisle.

Identify the airflow direction of each fan and power supply module by its coloring.

- Blue coloring indicates port-side exhaust airflow.

Note

To prevent the switch from overheating and shutting down, position the air intake for the switch in a cold aisle. The fan and power supply modules must have the same direction of airflow. To change the airflow direction for the switch, shutdown the switch before changing the modules.

Rack and Cabinet Requirements

Install these types of racks or cabinets for your switch:

- Standard perforated cabinets

- Solid-walled cabinets with a roof fan tray (bottom-to-top cooling)

- Standard open four-post Telco racks

Work with your cabinet vendors to determine which of their cabinets meet these requirements or see the Cisco Technical Assistance Center (TAC) for recommendations:

- Use a standard 19-inch (48.3-cm), four-post Electronic Industries Alliance (EIA) cabinet or rack with mounting rails that conform to English universal hole spacing per section 1 of the ANSI/EIA-310-D-1992 standard.

- The depth of a four-post rack must be 24 to 32 inches (61.0 to 81.3 cm) between the front and rear mounting rails (for proper mounting of the bottom-support brackets or other mounting hardware).

Also, you must have power receptacles that are located within reach of the power cords that are used with the switch.

Warning

Statement 1048—Rack Stabilization

The rack stabilizing mechanism must be in place, or the rack must be bolted to the floor before installation or servicing. Failure to stabilize the rack can cause bodily injury.

Clearance Requirements

Provide the chassis with adequate clearance between the chassis and any other rack, device, or structure so that you can properly install the it. Provide the chassis with adequate clearance to route cables, provide airflow, and maintain the switch. For the clearances required for an installation of this chassis in a four-post rack, see the figure.

- Planning How to Position the Chassis in the Rack

- Installing the Chassis in a Four-Post Rack

- Grounding the Chassis

- Starting the Switch

Installation Options with Rack-Mount Kits

The rack-mount kit enables you to install the switch into racks of varying depths. You can position the switch with easy access to either the port connections or the fan and power supply modules.

Install the switch using these rack-mount options:

- Rack-mount kit (NXK-ACC-KIT2-2RU) which you can order from Cisco.

For four post racks.

The rack or cabinet that you use must meet the requirements listed the in General Requirements for Cabinets and Racks section.

Note

You are responsible for verifying that your rack and rack-mount hardware comply with the guidelines that are described in this document.

Install a Rack

Before you install the switch, you must install a standard four-post, 19-inch EIA data center rack (or a cabinet that contains such a rack) that meets the requirements listed in Overview of Racks.

Procedure

Step 1

Bolt the rack to the concrete subfloor before moving the chassis onto it.

Warning

Statement 1048—Rack Stabilization

The rack stabilizing mechanism must be in place, or the rack must be bolted to the floor before installation or servicing. Failure to stabilize the rack can cause bodily injury.

Step 2

If the rack has bonded construction, connect it to the earth ground. This action enables you to easily ground the switch and its components and to ground your electrostatic discharge (ESD) wrist strap to prevent damaging discharges when you handle ungrounded components before installing them.

Step 3

Include one or two power sources at the rack. For AC power, provide a power receptacle. For DC power, provide a circuit breaker with terminals for connecting power cables.

Warning

Statement 1018—Supply Circuit

To reduce risk of electric shock and fire, take care when connecting units to the supply circuit so that wiring is not overloaded.

Note

If you are not using power redundancy or are using n+1 redundancy, you need only one power source. If you are using n+n redundancy, you need two power sources.

Unpacking and Inspecting a New Switch

Before you install a new chassis, unpack and inspect it to be sure that you have all the items that you ordered. Verify that the switch was not damaged during shipment. If anything is damaged or missing, contact your customer representative immediately.

Caution

When you handle the chassis or its components, follow ESD protocol at all times to prevent ESD damage. This protocol includes but is not limited to wearing an ESD wrist strap that you connect to the earth ground.

Tip

Do not discard the shipping container when you unpack the switch. Flatten the shipping cartons and store them. If you need to move or ship the system in the future, you will need this container.

Procedure

Step 1

Compare the shipment to the equipment list that is provided by your customer service representative. Verify that you have received all of the ordered items.

The shipment should include:

- Switch chassis, which includes these installed components:

- Two power supplies (any combination of these, with the airflow direction being the same as for the fan modules):

- fan modules (all fan and power supply modules must have the same airflow direction)

- Switch accessory kit

Step 2

Check the contents of the box for damage.

Step 3

If you notice any discrepancies or damage, send this information to your customer service representative by email:

- Invoice number of the shipper (see the packing slip)

- Model and serial number of the missing or damaged unit

- Description of the problem and how it affects the installation

Planning How to Position the Chassis in the Rack

The switch is designed so that you can have coolant air flow through the switch in one of two directions:

- Enter the port side and exhaust out the power supply side (port-side intake airflow)

- Enter the power supply side and exhaust out the port side (port-side exhaust airflow)

For port-side intake airflow, the switch must have port-side intake fan and AC power supply modules with one or more of these colorings:

For port-side exhaust airflow, the switch must have port-side exhaust fan and AC power supply modules with one or more of the following colorings:

- Blue coloring on fan modules and AC power supplies

Plan the positioning of the switch so that its ports are located close to ports on connected devices or so that the fan and power supply modules are conveniently located in a maintenance aisle. Order the modules that move coolant air in the appropriate direction from the cold aisle to the hot aisle.

Note

All fan and power supply modules in the same switch must operate with the same direction of airflow. The air intake portion of the switch must be located in a cold aisle.

Installing the Chassis in a Four-Post Rack

Before you install the chassis, be sure that the rack is fully secured to the data center floor.

- Installing the Switch using the NXK-ACC-KIT2-2RU Rack-Mount Kit

Installing the Switch using the NXK-ACC-KIT2-2RU Rack-Mount Kit

To install the switch, you must attach inner rails to the chassis, attach the outer rails to the rack, slide the switch onto the outer rails, and secure the switch to the rack with the retainer screws. Typically, the front of the rack is the side easiest to access for maintenance.

Before you begin

- You have inspected the switch shipment to ensure that you have everything ordered.

- Make sure that the switch rack-mount kit includes the following parts:

- Rack-mount inner rails (2)

- Rack-mount outer rails (2)

- Flat head screws (12)

- The rack is installed and secured to its location.

Procedure

Step 1

Install the two inner rails to the sides of the chassis using flat-head screws, as shown in the following illustration:

Step 2

Install the two outer rails to the front posts of the rack by aligning the rails to the post holes, as shown in the following illustration:

Step 3

Fasten the two outer rails to the front posts of the rack by pushing the latch into place, as shown in the following illustration:

Step 4

Install the two outer rails to the back posts of the rack by extending them into place, as shown in the following illustration:

Step 5

Fasten the two outer rails to the back posts of the rack by pushing the latch into place, as shown in the following illustration:

Step 6

If installing from the front of the rack, slide the chassis into the rack by aligning the inner rails into the outer rails, and sliding the chassis back until the front panel is flush with the front of the rack. Then secure the retainer screws on the inner rails into the rack, as shown in the following illustration:

Step 7

If installing from the back of the rack, slide the chassis into the rack by aligning the inner rails into the outer rails, and sliding the chassis forward until the front panel is flush with the front of the rack. Then slide the retainer screws out to align with the rack and then secure the thumb-screws on the inner rails into the rack, as shown in the following illustration:

Grounding the Chassis

The switch chassis is automatically grounded when you properly install the switch in a grounded rack with metal-to-metal connections between the switch and rack.

Note

Provide an electrical conducting path between the product chassis and the metal surface of the enclosure or rack in which it is mounted or to a grounding conductor. To ensure electrical continuity, use thread-forming type mounting screws that remove any paint or non-conductive coatings and establish a metal-to-metal contact. Remove any paint or other non-conductive coatings on the surfaces between the mounting hardware and the enclosure or rack. Clean the surfaces and apply an antioxidant before installation.

Ground the chassis, which is required if the rack is not grounded. Attach a customer-supplied grounding cable. Attach the cable to the chassis grounding pad and the facility ground.

Warning

Statement 1024—Ground Conductor

This equipment must be grounded. To reduce the risk of electric shock, never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.

Warning

Statement 1046—Installing or Replacing the Unit

To reduce risk of electric shock, when installing or replacing the unit, the ground connection must always be made first and disconnected last.

Before you begin

Before you can ground the chassis, connect to earth ground of the data center building.

Procedure

Step 1

Use a wire-stripping tool to remove approximately 0.75 inch (19 mm) of the covering from the end of the grounding wire. We recommend 6-AWG wire for the U.S. installations.

Step 2

Insert the stripped end of the grounding wire into the open end of the grounding lug. Use a crimping tool to crimp the lug to the wire. See the figure. Verify that the ground wire is securely attached to the grounding lug by attempting to pull the wire out of the crimped lug (tug test).

2 M4 screws are used to secure the grounding lug to the chassis

2

Grounding cable, with 0.75 in. (19 mm) of insulation that is stripped from one end, which is inserted into the grounding lug and crimped in place

Step 3

Secure the grounding lug to the chassis grounding pad with two M4 screws, see figure 1. Tighten the screws to 11 to 15 in-lb (1.24 to 1.69 Nm) of torque.

Step 4

Prepare the other end of the grounding wire and connect it to the facility ground.

Starting the Switch

Start the switch by connecting it to its dedicated power source. If you need n+n redundancy, connect each power supply in a switch to a different power source.

Note

This equipment is designed to boot up in less than 30 minutes, dependent on its neighboring devices being fully up and running.

Before you begin

- The switch must be installed and secured to a rack or cabinet.

- The switch must be adequately grounded.

- The rack must be close enough to the dedicated power source so that you can connect the switch to the power source by using the designated power cables.

- You have the designated power cables for the power supplies that you are connecting to the dedicated power sources.

Note

Depending on the outlet receptacle on your AC power distribution unit, you might need an optional jumper power cord to connect the switch to your outlet receptacle.

- The switch is not connected to the network (this includes any management or interface connections).

- The fan and power supply modules are fully secured in their chassis slots.

Procedure

Step 1

For any AC power supply, do this:

1. Using the recommended AC power cable for your country or region, connect one end to the AC power supply.

2. Connect the other end of the power cable to the AC power source.

Step 2

For any HVAC/HVDC power supply, connect it to a power source like this:

1. Using the recommended high voltage power cable for your country or region, connect the Anderson Power Saf-D-Grid connector on the power cable to the power receptacle on the power supply. Make sure that the connector clicks when fully pushed into the receptacle.

2. Connect the other end of the power cable to a power source.

- When connecting to an HVAC power source, insert the plug in a receptacle for the HVAC power source.

- When connecting to an HVDC power source, do this:

1. Verify that the power is turned off at a circuit breaker for the power source terminals.

2. Remove the nuts from each of the terminal posts for the power supply.

3. Place the power cable negative-wire terminal ring on the negative terminal for the power source and secure them with a terminal nut.

4. Place the power cable positive-wire terminal ring on the positive terminal for the power source and secure them with a terminal nut.

5. Place the power cable ground-wire terminal ring on the ground terminal for the power source and secure them with a terminal nut.

6. If there is a safety cover for the power source terminals, place and secure it over the terminals to avoid an electrical shock hazard.

7. Turn on the power at the power source circuit breaker.

Step 3

For any DC power supply, do this:

1. Turn off the circuit breaker for the power source to avoid an electrical shock hazard.

2. Verify that the power cable wires from the power source are connected to a connector block.

3. Insert the connector block into the receptacle on the power supply. Make sure that the connector block clicks when fully inserted in the receptacle and does not pull out.

4. If there is a safety cover for the terminals, place and secure it over the terminals to avoid an electrical shock hazard.

5. Turn on the power at the circuit breaker for the DC power source.

Step 4

Verify that the power supply LED is on and green.

Step 5

Listen for the fans; they should begin operating when the power supply is powered.

Step 6

After the switch boots, verify that these LEDs are lit:

- On the fan modules, the Status (STA or STS) LED is green.

If a fan module Status LED is not green, try reinstalling the fan module.

- After initialization, the switch chassis Status (labeled as STA or STS) LED is green.

Step 7

Verify that the system software has booted and the switch has initialized without error messages.

A setup utility automatically launches the first time that you access the switch and guides you through the basic configuration. For instructions on how to configure the switch and check module connectivity, see the appropriate Cisco Nexus 9000 Series configuration guide.

Chapter 4. Connecting the Switch to the Network

- Overview of Network Connections

- Connecting a Console to the Switch

- Creating the Initial Switch Configuration

- Setting Up the Management Interface

- Connecting Interface Ports to Other Devices

Overview of Network Connections

After you install the switch in a rack and power it up, make these network connections:

- Console connection—This is a direct local management connection that you use to initially configure the switch. Make this connection first to initially configure the switch and determine its IP address, which is needed for the other connections.

- Management connection—After you complete the initial configuration using a console, make this connection to manage all future switch configurations.

- Uplink and downlink interface connections—These are connections to hosts and servers in the network.

Each of these connection types is explained in one of these sections.

Note

When running cables in overhead or subfloor cable trays, we strongly recommend that you locate power cables and other potential noise sources as far away as practical from network cabling that terminates on Cisco equipment. In situations where long parallel cable runs cannot be separated by at least 3.3 feet (1 meter), we recommend that you shield any potential noise sources by housing them in a grounded metallic conduit.

Connecting a Console to the Switch

Before you create a network management connection for the switch or connect the switch to the network, create a local management connection through a console terminal. Then configure an IP address for the switch. Use the console to perform these functions, each of which can be performed through the management interface after you make that connection.

- Configure the switch using the command-line interface (CLI).

- Monitor network statistics and errors.

- Configure Simple Network Management Protocol (SNMP) agent parameters.

- Download software updates.

Make this local management connection between the asynchronous serial port on a supervisor module and a console device capable of asynchronous transmission. Typically, you use a computer terminal as the console device. On the supervisor modules, use the console serial port.

Note

Before you can connect the console port to a computer terminal, make sure that the computer terminal supports VT100 terminal emulation. The terminal emulation software makes communication between the switch and the computer possible during setup and configuration.

Before you begin

- The switch must be fully installed in its rack, connected to a power source, and grounded.

- The necessary cabling for the console, management, and network connections must be available.

- An RJ-45 rollover cable provided in the switch accessory kit.

- Network cabling is routed to the location of the installed switch.

Procedure

Step 1

Configure the console device to match these default port characteristics:

- 9600 baud

- 8 data bits

- 1 stop bit

- No parity

Step 2

Connect an RJ-45 rollover cable to the console port on the switch.

Find this cable in the accessory kit.

Step 3

Route the RJ-45 rollover cable to the console or a modem.

Step 4

Connect the other end of the RJ-45 rollover cable to the console or to a modem.

What to do next

You are ready to create the initial switch configuration. See Creating the Initial Switch Configuration.

Creating the Initial Switch Configuration

Before you begin

- A console device must be connected with the switch.

- The switch must be connected to a power source.

- Determine the IP address and the netmask that is needed for the Management (Mgmt0) interface.

Procedure

Step 1

Power up the switch by connecting each installed power supply to an AC circuit.

If you are using the input-source (n+n) power mode, connect half of the power supplies to one AC circuit. Connect the other half of the power supplies to another AC circuit.

The Input and Output LEDs on each power supply light up (green) when the power supply units are sending power to the switch. The software asks you to specify a password to use with the switch.

Step 2

Enter a new password for this switch.

The software checks the security strength of your password. It rejects your password if it does not meet these guidelines:

- At least eight characters.

- Minimizes or avoids the use of consecutive characters (such as "abcd").

- Minimizes or avoids repeating characters (such as "aaabbb").

- Does not contain recognizable words from the dictionary.

- Does not contain proper names.

- Contains both uppercase and lowercase characters.

- Contains numbers and letters.

Note

Clear text passwords cannot include the dollar sign ($) special character.

Tip

If a password is trivial (such as a short, easy-to-decipher password), the software will reject your password configuration. Configure a strong password as explained in this step. Passwords are case-sensitive.

When you enter a strong password, the software asks you to confirm the password.

Step 3

Enter the same password again.

If you enter the same password, the software accepts the password and begins asking a series of configuration questions.

Step 4

Until you are asked for an IP address, enter the default configuration for each question.

Repeat this step for each question until you are asked for the Mgmt0 IPv4 address.

Step 5

Enter the IP address for the management interface.

The software asks for the Mgmt0 IPv4 netmask.

Step 6

Enter a network mask for the management interface.

The software asks if you need to edit the configuration.

Step 7

Enter no, to not edit the configuration.

The software asks if you need to save the configuration.

Step 8

Enter yes to save the configuration.

What to do next

Set up the management interface for each supervisor module on the switch.

Setting Up the Management Interface

The RJ-45 and/or SFP management ports provide out-of-band management, which enables you to use the command-line interface (CLI) to manage the switch by its IP address. Use one of these ports depending on the cable and connectors that you are using to connect the management interface to the network.

Before you begin

- The switch must be powered on.

- The switch must be initially configured using a console.

Procedure

Step 1

Connect the management cable into the management port on the switch. For shorter connections, use a cable with RJ-45 connectors. For longer connections, use an optical cable with SFP transceivers (LH or SX type).

Note

Use only one of these management ports—the switch does not support the use of both management ports.

Step 2

Connect the other end of the cable to a 10/100/1000 or SFP port on a network device.

Connecting Interface Ports to Other Devices

After you perform the initial configuration for the switch and create a management connection, you are ready to connect the interface ports on the switch to other devices. Depending on the types of interface ports on the switch, use interface cables with QSFP28, QSFP+, SFP+, SFP transceivers, or RJ-45 connectors to connect the switch to other devices.

Note

When using SFP+ or SFP transceivers in a QSFP+ or QSFP28 uplink port, install a QSFP-to-SFP adapter, such as the CVR-QSFP-SFP10G adapter, in the QSFP port and then install the SFP+ or SFP transceiver. The switch automatically sets the port speed to the speed of the installed transceiver.

If the transceivers that you are using can be separated from their optical cables, install the transceivers without their cables before inserting the cables into the transceivers. This helps to prolong the life of both the transceiver and cables. When removing transceivers from the switch, remove the optical cable first and then remove the transceiver.

To determine which transceivers, adapters, and cables are supported by this switch, see the Cisco Transceiver Modules Compatibility Information document.

Chapter 5. Replacing Components

- Replacing a Fan Module During Operations

- Replacing a Power Supply Module

Replacing a Fan Module During Operations

All fan and power supply modules must have the same airflow direction or else an error can occur with the switch overheating and shutting down. You can determine the airflow direction of a fan module by the color of the stripe on the front of the module. If the fan module has a blue stripe for port-side exhaust airflow, the power supplies must have blue coloring for the same airflow direction. If the fan module has a burgundy stripe for port-side intake airflow, the power supplies must have burgundy coloring for the same airflow direction. To avoid over heating the switch, make sure that the fan modules are positioned in one of the following ways:

- For port-side exhaust airflow with blue coloring, position the fan modules in a cold aisle.

- For port-side intake airflow with burgundy coloring, position the ports in a cold aisle.

Before you begin

Before you can replace a fan module, ensure that the following conditions exist:

- The replacement fan module must have the same airflow direction as the other modules in the chassis.

If you must replace the fan module during operations and the above conditions are not met, leave the fan module that you need to replace in the chassis to preserve the designed airflow until you have the required module.

Procedure

Step 1

Remove the fan module that you need to replace as follows:

1. Place the removed module on an antistatic surface or in an antistatic bag. If possible, repack the module in its packing materials for safe shipping or storage.

Step 2

Follow these steps to replace the missing fan module within two minutes to avoid a shutdown.

1. Remove the replacement fan module from its packing materials and place it on an antistatic surface.

Hold the module by its handle and do not touch the electrical connectors on its backside. Also, to protect the electrical connectors, avoid letting them come in contact with anything other than the electrical connectors inside the chassis.

2. Position the fan module in front of the open fan slot (be sure that the backside of the module with the electrical connectors is positioned to enter the slot first) and slide the module all the way into the chassis until its front side comes in contact with the chassis. For the last 0.2 inches (0.5 cm), carefully mount the module onto the chassis connectors by pushing more firmly, but do not force the module if it does not move further (excessive force can damage the connectors).

Note

If you are not able to push the module all the way into the slot, carefully slide the module out of the slot and check its electrical connectors for damage. If damaged, contact Cisco Technical Assistance for help. If undamaged, repeat this step to reinstall the module.

3. Verify that the STS LED turns on and becomes green.

If the STS LED does not turn on, slide the module out of the chassis, and visually check the electrical connectors on the back side of the chassis for damage. If damaged, contact Cisco Technical Assistance for help. If undamaged, repeat the previous step to reinstall the module.

Replacing a Power Supply Module

The switch requires two power supplies for redundancy. With one power supply providing the necessary power for operations, replace the other power supply during operations as long as the new power supply has the same airflow direction as the other modules in the chassis.

Replace a power supply with another supported power supply that has the same power source type as the other installed power supply. Additionally, the airflow direction of the power supply must match or conform to the airflow direction of the installed fan modules. For the airflow direction used by the switch, see the coloring of the fan modules.

- Removing an AC Power Supply

- Removing a DC Power Supply

- Installing an AC Power Supply

- Installing a DC Power Supply

Removing an AC Power Supply

To remove an AC power supply, disconnect the power cable and remove the module from the chassis.

Before you begin

- To replace a power supply during operations, you must have a functioning power supply providing power to the switch while you replace the other power supply. If there is only one power supply installed in the switch and you need to replace it, install the new power supply in the open slot and power it up before removing the original power supply.

- Ensure that the chassis is grounded. For grounding instructions, see Grounding the Chassis.

Procedure

Step 1

Disconnect the power cord from the power receptacle on the power supply to be removed. Verify that the LED turns off.

Note

The LED might be on and amber colored. This indicates that the input power has been disconnected.

Step 2

Remove the power supply from the chassis by pushing and holding its thumb latch to the left and pulling the power supply part way out of the chassis.

Step 3

Place your other hand under the power supply to support it while you slide it out of the chassis.

Either place the power supply on an antistatic surface or pack it in its packing materials.

What to do next

You are ready to install the replacement power supply.

Removing a DC Power Supply

You can remove one power supply while the other one provides power to the switch.

To disconnect the power supply from its power cables, shut off the power from the power source and disconnect the connector for the power cables.

Procedure

Step 1

Turn off the circuit breaker for the power feed to the power supply that you are replacing.

Verify that the LEDs turn off on the power supply that you are removing.

Step 2

Remove the power cable from the power supply. Do this:

Step 3

Grasp the power supply handle while pressing the release latch towards the power supply handle.

Step 4

Pull the power supply out of the bay.

What to do next

You are ready to install a DC power supply in the open slot.

Installing an AC Power Supply

You can replace one power supply while the other one provides power to the switch.

Before you begin

- The power supply that you are installing must be capable of using the same airflow direction as the fan trays installed in the same switch. It must use the same type of power source as the other power supply installed in the same switch. (Do not mix AC and DC power supplies in the same switch.)

Note

If the power supply that you are replacing has a different color handle than the replacement power supply, verify that it has or will have the same airflow direction as the other modules in the switch.

- An AC power source must be within reach of the power cable that will be used with the replacement power supply. If you are using n+n power redundancy, there must be a separate power source for each power supply installed in the chassis. Otherwise, only one power source is required.

- There must be an earth-ground connection to the chassis that you are installing the replacement module. Typically, the chassis is grounded by its metal-to-metal connection with a grounded rack. If you need to ground the chassis, see Grounding the Chassis.

Procedure

Step 1

Holding the replacement power supply with one hand underneath the module and the other hand holding the handle, turn the power supply so that its release latch is on the side. Align the back end of the power supply (the end with the electrical connections) to the open power supply slot. Carefully slide the power supply all the way into the slot until it clicks into place.

Note

If the power supply does not fit into the open slot, turn the module over, before sliding it carefully into the open slot.

Step 2

Test the installation by trying to pull the power supply out of the slot without using the release latch.

If the power supply does not move out of place, it is secured in the slot. If the power supply moves, carefully press it all the way into the slot until it clicks into place.

Step 3

Attach the power cable to the electrical inlet on the front of the power supply.

Step 4

Verify that the other end of the power cable is attached to the appropriate power source for the power supply.

Note

Depending on the outlet receptacle on your power distribution unit, install the optional jumper cable to connect the switch to your outlet receptacle.

Step 5

Verify that the power supply is operational by making sure that the power supply LED is green.

Installing a DC Power Supply

You can replace one power supply while the other one provides power to the switch.

Before you begin

- The circuit breaker for the DC power source for the power supply must be turned off.

- The power supply that you are installing must be capable of using the same airflow direction as the fan trays installed in the same switch.

- A DC power source must be within reach of the power cable that will be used with the replacement power supply. If you are using n+n power redundancy, there must be a separate power source for each power supply installed in the chassis. Otherwise, only one power source is required.

- There must be an earth-ground connection to the chassis that you are installing the replacement module. Typically, the chassis is grounded by its metal-to-metal connection to a grounded rack. If you need to ground this chassis by another means, see Grounding the Chassis.

- We recommend 8-AWG wire for DC installation in the U.S.

- All DC power supplies have reverse polarity protection. When you inadvertently connect the input power (+) to the DC PSU’s – terminal and the input power – to the DC PSU’s (+) terminal, the PSU will not be damaged and will operate fine after the input power feeds are correctly wired.

Procedure

Step 1

Holding the replacement power supply with one hand underneath the module and the other hand holding the handle, turn the power supply so that its release latch is on the side. Align the back end of the power supply (the end with the electrical connections) to the open power supply slot. Carefully slide the power supply all the way into the slot until it clicks into place.

Note

If the power supply does not fit into the open slot, turn the module over. Carefully slide it into the open slot.

Step 2

If the DC power cables and a grounding cable are already connected to an electrical connector block, insert the block into the power receptacle on the power supply.

Step 3

Turn on the circuit breaker for the DC power source connected to the power supply.

Step 4

Verify that the power supply is operational by making sure that the power supply LED is green.

Rack Specifications

- Overview of Racks

- General Requirements for Cabinets and Racks

- Requirements Specific to Standard Open Racks

- Requirements Specific to Perforated Cabinets

- Cable Management Guidelines

Overview of Racks

Install the switch in these types of cabinets and racks, assuming an external ambient air temperature range of 0 to 104°F (0 to 40°C):

- Standard perforated cabinets

- Solid-walled cabinets with a roof fan tray (bottom to top cooling)

- Standard open racks

Note

- If you are using an enclosed cabinet, we recommend one of the thermally validated types, either standard perforated or solid-walled with a fan tray.

- We do not recommend using racks that have obstructions (such as power strips). The obstructions could impair access to field-replaceable units (FRUs).

General Requirements for Cabinets and Racks

The cabinet or rack must meet these requirements:

- Standard 19-inch (48.3 cm) (two- or four-post EIA cabinet or rack, with mounting rails that conform to English universal hole spacing per section 1 of ANSI/EIA-310-D-1992). For more information, see Requirements Specific to Perforated Cabinets.

- The minimum vertical rack space requirement per chassis is:

- For a one RU (rack unit) switch, 1.75 inches (4.4 cm)

- For a one and a half RU (rack unit) switch, 2.63 (6.68 cm)

- For a two RU (rack unit) switch, 3.5 inches (8.8 cm)

- For a three RU (rack unit) switch, 5.25 inches (13.3 cm)

- The width between the rack-mounting rails must be at least 17.75 inches (45.0 cm) if the rear of the device is not attached to the rack. For four-post EIA racks, this measurement is the distance between the two front rails.

Four-post EIA cabinets (perforated or solid-walled) must meet these requirements:

- The minimum spacing for the bend radius for fiber-optic cables should have the front-mounting rails of the cabinet offset from the front door by a minimum of 3 inches (7.6 cm).

- The distance between the outside face of the front mounting rail and the outside face of the back mounting rail should be 23.0 to 30.0 inches (58.4 to 76.2 cm) to allow for rear-bracket installation.

Requirements Specific to Standard Open Racks

If you are mounting the chassis in an open rack (no side panels or doors), ensure that the rack meets these requirements:

- The minimum vertical rack space per chassis must be equal to the rack unit (RU) of the chassis. One rack unit is equal to 1.75 inches (4.4 cm).

- The distance between the chassis air vents and any walls should be 2.5 inches (6.4 cm).

Requirements Specific to Perforated Cabinets

A perforated cabinet has perforations in its front and rear doors and side walls. Perforated cabinets must meet these requirements:

- The front and rear doors must have at least a 60 percent open area perforation pattern, with at least 15 square inches (96.8 square cm) of open area per rack unit of door height.

- The roof should be perforated with at least a 20 percent open area.

- The cabinet floor should be open or perforated to enhance cooling.

The Cisco R Series rack conforms to these requirements.

Cable Management Guidelines

To help with cable management, allow additional space in the rack above and below the chassis to make it easier to route all of the fiber optic or copper cables through the rack.
