Note

Before you install, operate, or service a server, review the Regulatory Compliance and Safety Information for important safety information.

Warning

IMPORTANT SAFETY INSTRUCTIONS

This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents. Use the statement number provided at the end of each warning to locate its translation in the translated safety warnings that accompanied this device.

Statement 1071

Warning

To prevent the system from overheating, do not operate it in an area that exceeds the maximum recommended ambient temperature of: 35° C (95° F).

Statement 1047

Warning

The plug-socket combination must be accessible at all times, because it serves as the main disconnecting device.

Statement 1019

Warning

This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that the protective device is rated not greater than: 250 V, 15 A.

Statement 1005

Warning

Installation of the equipment must comply with local and national electrical codes.

Statement 1074

Warning

This unit is intended for installation in restricted access areas. A restricted access area can be accessed only through the use of a special tool, lock, and key, or other means of security.

Statement 1017

Caution

To ensure proper airflow it is necessary to rack the servers using rail kits. Physically placing the units on top of one another or “stacking” without the use of the rail kits blocks the air vents on top of the servers, which could result in overheating, higher fan speeds, and higher power consumption. We recommend that you mount your servers on rail kits when you are installing them into the rack because these rails provide the minimal spacing required between the servers. No additional spacing between the servers is required when you mount the units using rail kits.

Caution

Avoid uninterruptible power supply (UPS) types that use ferroresonant technology. These UPS types can become unstable with systems such as the Cisco UCS, which can have substantial current draw fluctuations from fluctuating data traffic patterns.

When you are installing a server, use the following guidelines:

- Plan your site configuration and prepare the site before installing the server. See the Cisco UCS Site Preparation Guide for the recommended site planning tasks.

- Ensure that there is adequate space around the server to allow for accessing the server and for adequate airflow. The airflow in this server is from front to back.

- Ensure that the air-conditioning meets the thermal requirements listed in the Environmental Specifications.

- Ensure that the cabinet or rack meets the requirements listed in the Rack Requirements.

- Ensure that the site power meets the power requirements listed in the Power Specifications. If available, you can use an uninterruptible power supply (UPS) to protect against power failures.

Rack Requirements

The rack must be of the following type:

- A standard 19-in. (48.3-cm) wide, four-post EIA rack, with mounting posts that conform to English universal hole spacing, per section 1 of ANSI/EIA-310-D-1992.

- The rack-post holes can be square 0.38-inch (9.6 mm), round 0.28-inch (7.1 mm), #12-24 UNC, or #10-32 UNC when you use the Cisco-supplied slide rails.

- The minimum vertical rack space per server must be one rack unit (RU), equal to 1.75 in. (44.45 mm).

Supported Cisco Slide Rail Kits

The server supports the following rail kit options:

- Cisco part UCSC-RAIL-M6= (ball-bearing slide rail kit)

- Cisco part UCSC-CMA-C220M6= (cable management arm)

Rack Installation Tools Required

The slide rails sold by Cisco Systems for this server do not require tools for installation.

Slide Rail and Cable Management Arm Dimensions

The slide rails for this server have an adjustment range of 24 to 36 inches (610 to 914 mm).

The optional cable management arm (CMA) adds additional length requirements:

- The additional distance from the rear of the server to the rear of the CMA is 5.4 inches (137.4 mm).

- The total length of the server including the CMA is 35.2 inches (894 mm).

Grounding Requirements

The switch is sensitive to variations in voltage supplied by the power sources. Overvoltage, undervoltage, and transients (or 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. You can connect the grounding pad on the switch either directly to the earth-ground connection or to a fully bonded and grounded rack.

When you properly install the chassis in a grounded rack, the switch is grounded because it has a metal-to-metal connection to the rack. Alternatively, you can ground the chassis by using a customer-supplied grounding cable that meets your local and national installation requirements (we recommend 6-AWG wire for U.S. installations) connected to the chassis with a grounding lug (provided in the switch accessory kit) and to the facility ground.

Note

You automatically ground AC power supplies when you connect them to AC power sources. For DC power supplies, you must connect a grounding wire when wiring the power supply to the DC power source.

Installing the Server in a Rack

This section describes how to install the server in a rack using the supported rail kit (UCSC-RAIL-M6) that is sold by Cisco.

Warning

To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety:

This unit should be mounted at the bottom of the rack if it is the only unit in the rack.

When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.

If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack.

Step 9

Continue with Setting Up the System With the Cisco IMC Configuration Utility.

Setting Up the System With the Cisco IMC Configuration Utility

Before you begin

The following procedure is performed after you connect to the system and open the Cisco IMC Configuration Utility.

Procedure

Step 1

Set the NIC mode to Dedicated. The dedicated management port is used to access Cisco IMC for server management.

Step 2

Choose whether to enable DHCP for dynamic network settings, or to enter static network settings.

Note

Before you enable DHCP, you must preconfigure your DHCP server with the range of MAC addresses for this server. The MAC address is printed on a label on the rear of the server. This server has a range of six MAC addresses assigned to Cisco IMC. The MAC address printed on the label is the beginning of the range of six contiguous MAC addresses.

The static IPv4 and IPv6 settings include the following:

- The Cisco IMC IP address.

For IPv6, valid values are 1 - 127.

- The gateway.

For IPv6, if you do not know the gateway, you can set it as none by entering :: (two colons).

- The preferred DNS server address.

For IPv6, you can set this as none by entering :: (two colons).

Step 3

(Optional) Make VLAN settings.

Step 4

Press F1 to go to the second settings window, then continue with the next step.

From the second window, you can press F2 to switch back to the first window.

Step 5

(Optional) Set a hostname for the server.

Step 6

(Optional) Enable dynamic DNS and set a dynamic DNS (DDNS) domain.

Step 7

(Optional) If you check the Factory Default check box, the server reverts to the factory defaults.

Step 8

(Optional) Set a default user password.

Note

The default password is either "password" or "Insieme123". The Strong Password feature is enabled.

Step 9

(Optional) Enable auto-negotiation of port settings or set the port speed and duplex mode manually.

Note

Auto-negotiation is applicable only when you use the Dedicated NIC mode. Auto-negotiation sets the port speed and duplex mode automatically based on the switch port to which the server is connected. If you disable auto-negotiation, you must set the port speed and duplex mode manually.

Step 10

(Optional) Reset port profiles and the port name.

Step 11

Press F5 to refresh the settings that you made. You might have to wait about 45 seconds until the new settings appear and the message, “Network settings configured” is displayed before you reboot the server in the next step.

Step 12

Press F10 to save your settings and reboot the server.

Note

If you chose to enable DHCP, the dynamically assigned IP and MAC addresses are displayed on the console screen during bootup.

What to do next

Use a browser and the IP address of the Cisco IMC to connect to the Cisco IMC management interface. The IP address is based upon the settings that you made (either a static address or the address assigned by your DHCP server).

Note

The factory default username for the server is admin. The default password is either "password" or "Insieme123".

To manage the server, see the Cisco UCS C-Series Rack-Mount Server Configuration Guide or the Cisco UCS C-Series Rack-Mount Server CLI Configuration Guide for instructions on using those interfaces for your Cisco IMC release. The links to the configuration guides are in the Cisco UCS C-Series Documentation Roadmap.

- To switch from host serial to Cisco IMC CLI, press Esc+9.

You must enter your Cisco IMC credentials to authenticate the connection.

- To switch from Cisco IMC CLI to host serial, press Esc+8.

Note

You cannot switch to Cisco IMC CLI if the serial-over-LAN (SOL) feature is enabled.

- After a session is created, it is shown in the CLI or web GUI by the name serial.

Smart Access USB

This server supports the Smart Access USB feature. The board management controller (BMC) in this server can accept a USB mass storage device and access the data on it. This feature allows you to use the front-panel USB device as a medium to transfer data between the BMC and the user without need for network connectivity. This can be useful, for example, when remote BMC interfaces are not yet available, or are not accessible due to network misconfiguration.

- This feature has the following requirements:

- The KVM cable (Cisco PID N20-BKVM) connected to the front panel KVM console connector.

- A USB storage device connected to one of the USB 2.0 connectors on the KVM cable. The USB device must draw less than 500 mA to avoid disconnect by the current-protection circuit.

Note

Any mouse or keyboard that is connected to the KVM cable is disconnected when you enable Smart Access USB.

- You can use USB 3.0-based devices, but they will operate at USB 2.0 speed.

- We recommend that the USB device have only one partition.

- The file system formats supported are: FAT16, FAT32, MSDOS, EXT2, EXT3, and EXT4. NTFS is not supported.

- The front-panel KVM connector has been designed to switch the USB port between Host OS and BMC.

- Smart Access USB can be enabled or disabled using any of the BMC user interfaces. For example, you can use the Cisco IMC Configuration Utility that is accessed by pressing F8 when prompted during bootup.

- Enabled: the front-panel USB device is connected to the BMC.

- Disabled: the front-panel USB device is connected to the host.

- In a case where no management network is available to connect remotely to Cisco IMC, a Device Firmware Update (DFU) shell over serial cable can be used to generate and download technical support files to the USB device that is attached to front panel USB port.

Hot Swap vs Hot Plug

Some components can be removed and replaced without shutting down and removing power from the server. This type of replacement has two varieties: hot-swap and hot-plug.

- Hot-swap replacement—You do not have to shut down the component in the software or operating system. This applies to the following components:

- SAS/SATA hard drives

- SAS/SATA solid state drives

- Cooling fan modules

- Power supplies (when redundant as 1+1)

- Hot-plug replacement—You must take the component offline before removing it for the following component:

- NVMe PCIe solid state drives

Removing and Replacing Components

Warning

Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place.

Statement 1029

Caution

When handling server components, handle them only by carrier edges and use an electrostatic discharge (ESD) wrist-strap or other grounding device to avoid damage.

Tip

You can press the unit identification button on the front panel or rear panel to turn on a flashing, blue unit identification LED on both the front and rear panels of the server. This button allows you to locate the specific server that you are servicing when you go to the opposite side of the rack. You can also activate these LEDs remotely by using the Cisco IMC interface.

Replacing SAS/SATA Hard Drives or Solid State Drives

Note

You do not have to shut down the server or drive to replace SAS/SATA hard drives or SSDs because they are hot-swappable. To replace an NVMe PCIe SSD drive, which must be shut down before removal, see Replacing a Front-Loading NVMe SSD.

- SAS/SATA Drive Population Guidelines

- 4K Sector Format SAS/SATA Drives Considerations

- Replacing a SAS/SATA Drive

SAS/SATA Drive Population Guidelines

The server is orderable in the following version:

- ND-NODE-L4 — Small form-factor (SFF) drives, with 10-drive backplane. Supports up to 10 2.5-inch SAS/SATA drives. Drive bays 1 and 2 support NVMe SSDs.

Drive bay numbering is shown in the following figures.

Drive Bay Numbering

Observe these drive population guidelines for optimum performance:

- When populating drives, add drives to the lowest-numbered bays first.

- Keep an empty drive blanking tray in any unused bays to ensure proper airflow.

- You can mix SAS/SATA hard drives and SAS/SATA SSDs in the same server. However, you cannot configure a logical volume (virtual drive) that contains a mix of hard drives and SSDs. That is, when you create a logical volume, it must contain all SAS/SATA hard drives or all SAS/SATA SSDs.

4K Sector Format SAS/SATA Drives Considerations

- You must boot 4K sector format drives in UEFI mode, not legacy mode. UEFI mode is the system default. Only if the mode has been changed and must be changed back to UEFI mode, see the following procedure.

- Do not configure 4K sector format and 512-byte sector format drives as part of the same RAID volume.

- For operating system support on 4K sector drives, see the interoperability matrix tool for your server: Hardware and Software Interoperability Matrix Tools

Procedure

Replacing a SAS/SATA Drive

Drive Bay Numbering

Front-Loading NVME SSD Requirements and Restrictions

Observe these requirements:

- Hot-plug support must be enabled in the system BIOS. If you ordered the system with NVMe drives, hot-plug support is enabled at the factory.

- The NVMe-optimized, SFF 10-drive version, supports NVMe drives only.

Observe these restrictions:

- NVMe SFF 2.5-inch SSDs support booting only in UEFI mode. Legacy boot is not supported. For instructions on setting up UEFI boot, see 4K Sector Format SAS/SATA Drives Considerations.

- You cannot control NVMe PCIe SSDs with a SAS RAID controller because NVMe SSDs interface with the server via the PCIe bus.

- UEFI boot is supported in all supported operating systems. Hot-insertion and hot-removal are supported in all supported operating systems except VMWare ESXi.

Enabling Hot-Plug Support in the System BIOS

Hot-plug (OS-informed hot-insertion and hot-removal) is disabled in the system BIOS by default.

- If the system was ordered with NVMe PCIe SSDs, the setting was enabled at the factory. No action is required.

- If you are adding NVMe PCIe SSDs after-factory, you must enable hot-plug support in the BIOS. See the following procedures.

Enabling Hot-Plug Support Using the BIOS Setup Utility

Replacing a CPU and Heatsink

Caution

CPUs and their sockets are fragile and must be handled with extreme care to avoid damaging pins. The CPUs must be installed with heatsinks and thermal interface material to ensure cooling. Failure to install a CPU correctly might result in damage to the server.

Procedure

Step 1

Remove the existing CPU/heatsink assembly from the server:

1. Shut down and remove power from the server as described in Shutting Down and Removing Power From the Server.

2. Slide the server out the front of the rack far enough so that you can remove the top cover. You might have to detach cables from the rear panel to provide clearance.

Caution

If you cannot safely view and access the component, remove the server from the rack.

3. Remove the top cover from the server as described in Removing the Server Top Cover.

4. Use the T-20 Torx driver that is supplied with the replacement CPU to loosen the four captive nuts that secure the assembly to the motherboard standoffs.

Note

Alternate loosening the heatsink nuts evenly so that the heatsink remains level as it is raised. Loosen the heatsink nuts in the order shown on the heatsink label: 4, 3, 2, 1, 6, 5.

5. Remove the heatsink.

6. Loosening the three socket frame screws.

7. Open the socket frame.

8. Open the rail frame.

9. Take out the CPU with carrier frame.

Step 2

Install the new CPU:

Caution

The CPU contacts and pins are extremely fragile. In this step, use extreme care to avoid touching or damaging the CPU contacts or the CPU socket pins.

1. Grasping the CPU only by the handling tab on its carrier frame, carefully slide it down into the open rail frame.

2. Gently close the rail frame down to the flat, closed position.

3. Gently close the socket frame down to the flat, closed position.

4. Tighten the three screws on the socket frame in this order: 1, 2, 3.

Step 3

Apply new TIM to the heatsink:

Note

The heatsink must have new TIM on the heatsink-to-CPU surface to ensure proper cooling and performance.

- If you are installing a new heatsink, it is shipped with a pre-applied pad of TIM. Go to step 5.

- If you are reusing a heatsink, you must remove the old TIM from the heatsink and then apply new TIM to the CPU surface from the supplied syringe. Continue with step a below.

1. Apply the cleaning solution that is included with the heatsink cleaning kit (UCSX-HSCK=) to the old TIM on the heatsink and let it soak for a least 15 seconds.

2. Wipe all of the TIM off the heatsink using the soft cloth that is included with the heatsink cleaning kit. Be careful to avoid scratching the heatsink surface.

3. Using the syringe of TIM provided with the new CPU (UCS-CPU-TIM=), apply 4 cubic centimeters of thermal interface material to the top of the CPU. Use the pattern shown below to ensure even coverage.

Thermal Interface Material Application Pattern

Caution

Use only the correct heatsink for your CPUs to ensure proper cooling.

Step 4

Install the heatsink to the CPU:

1. Align the heatsink over the CPU socket. Align the triangle-mark on the heatsink with the triangle-mark on the socket frame.

2. Use a T-20 Torx driver to tighten the six captive screws that secure the heatsink.

Caution

Alternate tightening the heatsink screws evenly so that the heatsink remains level while it is lowered. Tighten the heatsink screws in the order shown on the heatsink label (1, 2, 3, 4, 5, 6).

Step 5

Reconnect any cables that you removed.

Step 6

Power on the server.

Additional CPU-Related Parts to Order with RMA Replacement CPUs

When a return material authorization (RMA) of the CPU is done on a Cisco UCS C-Series server, additional parts might not be included with the CPU spare. The TAC engineer might need to add the additional parts to the RMA to help ensure a successful replacement.

Note

The following items apply to CPU replacement scenarios. If you are replacing a system chassis and moving existing CPUs to the new motherboard, you do not have to separate the heatsink from the CPU.

Scenario 1—You are reusing the existing heatsinks or moving CPUs and heatsinks to a new node:

- Heatsink cleaning kit (UCSX-HSCK=)

One cleaning kit can clean up to four CPUs.

- Thermal interface material (TIM) kit (UCS-CPU-TIM=)

One TIM kit covers one CPU.

Scenario 2—You are replacing the existing heatsinks:

- Heatsink: UCSC-HSHP-225M6=

New heatsinks have a pre-applied pad of TIM.

- Heatsink cleaning kit (UCSX-HSCK=)

One cleaning kit can clean up to four CPUs.

A CPU heatsink cleaning kit is good for up to four CPU and heatsink cleanings. The cleaning kit contains two bottles of solution, one to clean the CPU and heatsink of old TIM and the other to prepare the surface of the heatsink.

New heatsink spares come with a pre-applied pad of TIM. It is important to clean any old TIM off of the CPU surface prior to installing the heatsinks. Therefore, even when you are ordering new heatsinks, you must order the heatsink cleaning kit.

Replacing Memory DIMMs

Caution

DIMMs and their sockets are fragile and must be handled with care to avoid damage during installation.

Caution

Cisco does not support third-party DIMMs. Using non-Cisco DIMMs in the server might result in system problems or damage to the motherboard.

Note

To ensure the best server performance, it is important that you are familiar with memory performance guidelines and population rules before you install or replace DIMMs.

- DIMM Population Rules and Memory Performance Guidelines

- Replacing DIMMs

DIMM Population Rules and Memory Performance Guidelines

This topic describes the rules and guidelines for maximum memory performance.

DIMM Slot Numbering

The following figure shows the numbering of the DIMM slots on the motherboard.

DIMM Slot Numbering

DIMM Population Rules

Observe the following guidelines when installing or replacing DIMMs for maximum performance:

- Each CPU supports eight memory channels, A through H.

- CPU 1 supports channels P1 A1, P1 A2, P1 B1, P1 B2, P1 C1, P1 C2, P1 D1, P1 D2, P1 E1, P1 E2, P1 F1, P1 F2, P1 G1, P1 G2, P1 H1, and P1 H2.

- CPU 2 supports channels P2 A1, P2 A2, P2 B1, P2 B2, P2 C1, P2 C2, P2 D1, P2 D2, P2 E1, P2 E2, P2 F1, P2 F2, P2 G1, P2 G2, P2 H1, and P2 H2.

- Each channel has two DIMM sockets (for example, channel A = slots A1, A2).

- When both CPUs are installed, populate the DIMM slots of each CPU identically.

- In a single-CPU configuration, populate the channels for CPU1 only (P1 A1 through P1 H2).

- For optimal performance, populate DIMMs in the order shown in the following table, depending on the number of CPUs and the number of DIMMs per CPU. If your server has two CPUs, balance DIMMs evenly across the two CPUs as shown in the table.

Note

The sections below list recommended configurations. Using 5, 7, 9, 10, or 11 DIMMs per CPU is not recommended.

Memory Population Order

Memory slots are color coded, blue and black. The color coded channel population order is blue slots first, then black.

The following tables show the memory population order for each memory option.

All populated (A1,A2) through (H1, H2)

- The maximum combined memory allowed in the 16 DIMM slots controlled by any one CPU is 16 x 256 GB.

- Memory mirroring reduces the amount of memory available by 50 percent because only one of the two populated channels provides data. When memory mirroring is enabled, you must install DIMMs in even numbers of channels.

- NVIDIA M-Series GPUs can support only less-than 1 TB memory in the server.

- NVIDIA P-Series GPUs can support 1 TB or more memory in the server.

- AMD FirePro S7150 X2 GPUs can support only less-than 1 TB memory in the server.

- Observe the DIMM mixing rules shown in the following table.

DIMM Mixing Rules

DIMM Parameter

DIMMs in the Same Channel

DIMMs in the Same Bank

DIMM Capacity

For example, 8GB, 16GB, 32GB, 64GB, 128GB

You can mix different capacity DIMMs in the same channel (for example, A1, A2).

You cannot mix DIMMs with different capacities and Revisions in the same bank (for example A1, B1). The Revision value depends on the manufactures. Two DIMMs with the same PID can have different Revisions.

DIMM speed

For example, 2666 GHz

You can mix speeds, but DIMMs will run at the speed of the slowest DIMMs/CPUs installed in the channel.

You cannot mix DIMMs with different speeds and Revisions in the same bank (for example A1, B1). The Revision value depends on the manufactures. Two DIMMs with the same PID can have different Revisions.

DIMM type

RDIMMs or LRDIMMs

You cannot mix DIMM types in a channel.

You cannot mix DIMM types in a bank.

Memory Mirroring

The CPUs in the server support memory mirroring only when an even number of channels are populated with DIMMs. If one or three channels are populated with DIMMs, memory mirroring is automatically disabled.

Memory mirroring reduces the amount of memory available by 50 percent because only one of the two populated channels provides data. The second, duplicate channel provides redundancy.

Replacing DIMMs

Identifying a Faulty DIMM

Each DIMM socket has a corresponding DIMM fault LED, directly in front of the DIMM socket. See Internal Diagnostic LEDs for the locations of these LEDs. When the server is in standby power mode, these LEDs light amber to indicate a faulty DIMM.

Procedure

Step 1

Remove an existing DIMM:

1. Shut down and remove power from the server as described in Shutting Down and Removing Power From the Server.

2. Slide the server out the front of the rack far enough so that you can remove the top cover. You might have to detach cables from the rear panel to provide clearance.

Caution

If you cannot safely view and access the component, remove the server from the rack.

3. Remove the top cover from the server as described in Removing the Server Top Cover.

4. Remove the air baffle that covers the front ends of the DIMM slots to provide clearance.

5. Locate the DIMM that you are removing, and then open the ejector levers at each end of its DIMM slot.

Step 2

Note

Before installing DIMMs, see the memory population rules for this server: DIMM Population Rules and Memory Performance Guidelines.

1. Align the new DIMM with the empty slot on the motherboard. Use the alignment feature in the DIMM slot to correctly orient the DIMM.

2. Push down evenly on the top corners of the DIMM until it is fully seated and the ejector levers on both ends lock into place.

3. Replace the top cover to the server.

4. Replace the server in the rack, replace cables, and then fully power on the server by pressing the Power button.

Replacing a Mini-Storage Module

The mini-storage module plugs into a motherboard socket to provide additional internal storage. The module is available in two different versions:

- M.2 SSD Carrier—provides two M.2 form-factor SSD sockets.

Note

The Cisco IMC firmware does not include an out-of-band management interface for the M.2 drives installed in the M.2 version of this mini-storage module (UCS-MSTOR-M2). The M.2 drives are not listed in Cisco IMC inventory, nor can they be managed by Cisco IMC. This is expected behavior.

Replacing Power Supplies

The server can have one or two Titanium 80PLUS rated power supplies. When two power supplies are installed they are redundant as 1+1 by default, but they also support cold redundancy mode. Cold redundancy (CR) suspends power delivery on one or more power supplies and forces the remainder of the load to be supplied by the active PSU(s). As a result, total power efficiency is improved by best utilizing the PSU efficiency when compared to load characteristics.

- See also Power Specifications for more information about the power supplies.

- See also Rear-Panel LEDs for information about the power supply LEDs.

Replacing a SAS Storage Controller Card (RAID or HBA)

For hardware-based storage control, the server can use a Cisco modular SAS RAID controller or SAS HBA that plugs into a dedicated, vertical socket on the motherboard.

- Storage Controller Card Firmware Compatibility

- Replacing a SAS Storage Controller Card (RAID or HBA)

Storage Controller Card Firmware Compatibility

Firmware on the storage controller (RAID or HBA) must be verified for compatibility with the current Cisco IMC and BIOS versions that are installed on the server. If not compatible, upgrade or downgrade the storage controller firmware using the Host Upgrade Utility (HUU) for your firmware release to bring it to a compatible level.

Note

For servers running in standalone mode only: After you replace controller hardware (UCSC-RAID-M6, UCSC-RAID-M6HD, UCSC-SAS-M6, or UCSC-SAS-M6HD), you must run the Cisco UCS Host Upgrade Utility (HUU) to update the controller firmware, even if the firmware Current Version is the same as the Update Version. This is necessary to program the controller's suboem-id to the correct value for the server SKU. If you do not do this, drive enumeration might not display correctly in the software. This issue does not affect servers controlled in UCSM mode.

See the HUU guide for your Cisco IMC release for instructions on downloading and using the utility to bring server components to compatible levels: HUU Guides.
