Installing the system-board assembly

Use this information to install the system-board assembly.

Note

This procedure should be performed only by trained service technicians.

Before you install the system-board assembly, complete the following steps:

Read Safety and Installation guidelines.
If the compute node is installed in an Flex System chassis, remove it (see Removing a compute node from a chassis for instructions).
Carefully lay the compute node on a flat, static-protective surface, orienting the compute node with the bezel pointing toward you.
Obtain the following for use during the replacement procedure (see Parts listing, Types 2585 and 7906).
- Alcohol wipes
- Bezel
- RFID tag (required only if the compute node came with a RFID tag attached to the bezel)
- Thermal grease

Important

When you replace the system board, you must update the compute node with the latest firmware or restore the preexisting firmware. Make sure that you have the latest firmware or a copy of the preexisting firmware before you proceed. See Updating firmware and device drivers for more information.

To install the system-board assembly, complete the following steps.

Install all of the components in the following list that you removed from the old system-board assembly onto the new system-board assembly:
- DIMMs and air baffles (see Installing a DIMM).
- I/O expansion adapters (see Installing an I/O expansion adapter).
- Fabric connector. (see Installing a fabric connector).
- ServeRAID controller. (see Installing a ServeRAID controller).
- Hard disk drives and hard disk drive fillers (see Installing a hot-swap hard disk drive).
- Microprocessors, heat sinks, and microprocessor heat-sink fillers. Use the microprocessor installation tool that comes with the replacement microprocessor to remove each microprocessor from the system-board assembly and install each one immediately in the new system-board assembly (see Removing a microprocessor and heat sink and Installing a microprocessor and heat sink).
- Hard disk drive backplane (see Installing the hard disk drive backplane).
If you are installing a new system-board assembly and did not install the old bezel on the new system-board assembly, carefully remove the bezel from the old system-board assembly and install it on the new system-board assembly (see Removing the bezel and Installing the bezel). If the old bezel will not attach securely to the new system-board assembly, remove the Tag from the lower right corner of the old bezel and install it on the lower right corner of the new bezel that shipped with the new system-board assembly; then, install the new bezel on the new system-board assembly.

After you install the system-board assembly, complete the following steps:

Install the cover onto the compute node (see Installing the compute node cover for instructions).
Install the compute node into the chassis (see Installing a compute node in a chassis for instructions).
Use the CMM Web Interface to restore the IP address of the compute node IMM. See Starting the web interface for more information.
Note
If you configured static IP addresses, you will not be able to access the node remotely or from the FSM until the IP address of the IMM is restored.
If any Features on Demand (FOD) features are installed in the compute node, see the instructions in the Features on Demand User's Guide to reactivate these features. To download this document, go to the Lenovo Features on Demand website, log in, and click Help.
Update the Universal Unique Identifier (UUID) and the Vital Product Data (VPD). Use the Advanced Settings Utility to update the UUID and VPD in the UEFI-based compute node (see Updating the Universally Unique Identifier and DMI/SMBIOS data).
Update the compute node with the latest firmware or restore the preexisting firmware (see Updating firmware and device drivers for more information).
