Introduction

This document describes the care and use of Catalyst switch equipment including cables, connectors, power supplies, and cords.

Prerequisites

Requirements

You must identify the part or model number of your switch/supervisor, switching module, or power supply in order to use this document effectively. Do this by visual inspection, or issue the show module command where possible.

Components Used

This document is not restricted to specific software and hardware versions.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.

Conventions

Refer to Cisco Technical Tips Conventions  for more information on document conventions.

Background Information

This document is a guide to cables and connectors for Catalyst 6500/6000, 5500/5000, and 4500/4000 series switching modules and Catalyst 2900/3500 XL, 2940, 2970, 2950/2955, 3550, and 3750 series fixed-configuration switches. AC power supplies, connectors, and cords for these switches are also covered.

Console and Aux Port Cables

Different Catalyst Supervisor Engines use either a rolled or a straight-through cable in order to connect a terminal or modem to the console port. Refer to these documents for information on how to connect a terminal or modem to the console port of Catalyst series switches:

- Connecting a Terminal to the Console Port on Catalyst Switches

- Connecting a Modem to the Console Port on Catalyst Switches

Auxiliary (AUX) ports on Layer 3 (L3) switches or modules behave much the same way as AUX ports on routers and are used to connect modems. Refer to Modem-Router Connection Guide  for information on how to connect a modem to an AUX port.

Which RJ-45 Ethernet Cable Do I Use?

A common question that concerns RJ-45 unshielded twisted pair (UTP) Ethernet cable concerns how to distinguish between rolled, straight-through, and crossover cables, and when to use them. Use the comparison guide found in the Configure Cable Requirements for Console and AUX Ports  in order to see the difference between these cables.

Cables to Hubs, Switches, Routers, and Workstations

Crossover and straight-through cables are used in order to connect switch ports or interfaces to network devices. Consult this table in order to see when to use each of these cable types. Find the device in the left-hand column and match it up with another device in the top row. The intersection of these two devices gives you the cable type used to connect them together.

Note: The ports on Catalyst switches that run Cisco IOS® Software (Native) can be configured to act as Layer 2 (L2) or Layer 3 (L3) ports. When you connect the RJ-45 cable from a Layer 3 port, which acts as a router port, to other devices, use the previous table. In summary, the cables used do not change, regardless of whether the port is configured to be in Layer 2 (switch port) or Layer 3 (router port) mode.

Most Common Cable Connectors

These diagrams show some of the most common cable types and connectors used on Catalyst switches.

RJ-45

RJ-21 Telco

This is used in order to connect to 10/100 or 10/100/1000 Ethernet ports and 1000Base-T Gigabit Interface Converter (GBIC) or small form factor pluggable (SFP) GBIC ports. 10/100/1000 Ethernet ports must use four twisted-pair Category 5, 5e or 6 cables.

This is used in order to connect to 10/100BASE-TX RJ-21 telco interfaces. Use Category 5 UTP cables with male RJ-21.

MT-RJ Fiber-Optic

SC Fiber-Optic

This is used in order to connect to 100Base-FX fiber-optic ports. Use multimode fiber (MMF) cables with MT-RJ connectors.

This is used in order to connect to 100Base-FX, 1000Base-SX, Long Wavelength/Long Haul (LX/LH) and ZX fiber-optic ports or GBICs. Use MMF or single-mode fiber (SMF) fiber-optic cable.

LC Fiber-Optic

GigaStack

This is used in order to connect to SFP fiber-optic module ports.

This is used in order to connect to GigaStack GBIC ports. Cisco GigaStack technology uses proprietary GBICs and cables.

StackWise

This is used in order to connect to StackWise ports on the rear panel of Catalyst 3750 switches. Cisco StackWise technology uses proprietary connectors and cables.

GBIC and SFP Connectors

Many Catalyst switches, Supervisor Engines and switching modules have removable Gigabit Interface Converters (GBICs) or small form factor pluggable (SFP)-type connectors. These diagrams show some of the most common GBIC and SFP connectors used on Catalyst switches.

Note: A Catalyst 2950 switch is used for demonstration purposes.

1000Base-X

AC Power Supplies, Connectors, and Cords for Catalyst Switches

In this section you see the summary of AC power supplies, power connectors, and cords for Catalyst 6500/6000, 5500/5000 and 4500/4000 series, and Catalyst 3750, 2950, 2940, and 2900/3500XL series switches. Refer to the Power Installation Guidelines in the tables that correspond in the next section for international power requirements, DC power requirements, and other technical specifications.

Different Modules require different amount of power. Inline Power modules supplies the power to the IP phones. Cisco has inline power module to power the IP phones. You have to choose the correct power supply in order to support the various line cards, modules and Supervisor Engines on the switch. Cisco offers a tool called the Cisco Power Calculator  which can be used in order to choose the correct power supply for your switch. Launch the Cisco Power Calculator  and fill out the Product family, Supervisor Engine, Input voltage, line cards and the number of PoE devices. IP phones are the example for PoE devices and most of the IP phones belong to IEEE 802.3af Device - Class 2 (7W). Then the power calculator shows the results of different choices of power supplies. From that, you can choose the required power supply. The power supplies successfully operate at their greatest capacity if the input voltage is between 200 and 240 volts AC.

Catalyst 6500/6000 Series Switch Power Supplies and Cables

This table is a quick reference for the available power supplies and cables in North American standard. Refer to Catalyst 6500 Power Supply Specifications  for the detailed specifications you can. These few points are important to know:

- The 950W (PWR-950-AC), 950W DC (PWR-950-DC) and 1400W AC (PWR-1400-AC) are used only with the Catalyst 6503 and Catalyst 6503-E Switches.

- The Power supplies 1000W and 1300W can be used only with Catalyst 6506, 6509, and 6509-NEB-A switches. The Supervisor Engines SUP32 and SUP720 are incompatible when 1000W and 1300W power supplies are used.

- With a fully populated Catalyst 6513 switch, two 2500 W power supplies are not fully redundant.

- If you operate the 2500 W power supply at the low range input (100 to 120 VAC), it is not redundant in a fully populated Catalyst 6509, Catalyst 6509-E, Catalyst 6509-NEB, or Catalyst 6509-NEB-A switch.

- The Power supplies 2500W, 2700W, and 3000W can operate at two different voltage levels (110Vac and 220Vac). The Power supply output depends on the supplied input AC power. This table shows the power ouput:

Power Supply

Power Output at 110Vac, 16A

Power Output at 220Vac, 16A

1300W

2500W

2700W

1350W

2700W

3000W

1400W

3000W

- The AC power cords are hardwired to the 4000W Power supplies (WS-CAC-4000W-US=). It supports only NEMA L6-30.

- The 6000W power supply cannot be installed in the Catalyst 6503, Catalyst 6503-E, and Catalyst 6504-E switch chassis.

- When 6000W power supply is used with the chassis Catalyst 6506, 6509, 6509-NEB, and 6509-NEB-A, it operates at 4000W maximum output. It operates at 6000W maximum output when it is used with Catalyst 6506-E, 6509-E, and 6513.

- 6000W power supply has two AC Power inputs. These are the various combinations of AC inputs and the corresponding net power output:

Note: If you have 110Vac power inputs, you have to connect both the AC inputs of the 6000W power supply in order to power on the switch.

- The Catalyst 6500 series switches allow you to mix AC-input and DC-input power supplies in the same chassis.

The modules have different power requirements, and some configurations require more power than a single power supply can provide. The power management feature allows you to power all installed modules with two power supplies. But, redundancy is not supported in this configuration because the total power drawn from both power supplies is at no time greater than the capability of one supply. Refer to the Power Management and Environmental Monitoring  chapter of the Catalyst 6500 Software Configuration Guide for the detailed explanation of power redundancy.

Note: This document does not discuss the total power available with the currently shipped power supplies for Catalyst 6500/6000 series switches or the amount drawn from each Catalyst 6500/6000 series line card. Refer to the document Power Management for Catalyst 6000 Series Switches for this information.
