Removing the system-board components for base-assembly replacement

Use this information to remove the system-board components as part of the procedure to replace the base assembly.

Notes
  1. This procedure should be performed only by trained service technicians.
  2. The base assembly includes the chassis and system board.
  3. If possible, back up all compute node settings, including the settings for any options installed in the compute node. You can backup and restore system settings using the Advanced Setup Utility (ASU) (see the Advanced Settings Utility (ASU) for Lenovo x86 servers website for information and instructions).
Before you remove the system-board components, complete the following steps:
  1. Read Safety and Installation guidelines.
  2. If the compute node is installed in a Lenovo Flex System chassis, remove it (see Removing a compute node from a chassis for instructions).
  3. Carefully lay the compute node on a flat, static-protective surface, orienting the compute node with the bezel pointing toward you.
  4. Obtain the following items for use during the replacement procedure (see Parts listing, Types 7196 and 4258):
    • Alcohol wipes
    • Thermal grease
    • RFID tag (required only if the compute node came with a RFID tag attached to the bezel)
Important
When you replace the base assembly, 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.

See System-board layouts for more information about the locations of the connectors, jumpers, and LEDs on the system board.

To remove the components from the system-board assembly, complete the following steps:


remove the components from the system-board assembly

  1. Remove the cover (see Removing the compute node cover).
  2. Remove all of the installed components in the following list from the system-board assembly; then, place them on a static-protective surface or install them on the new system-board assembly.
  3. Remove the left- and right-bezels (see Removing the bezel).

If you are instructed to return the base assembly, follow all packaging instructions, and use any packaging materials for shipping that are supplied to you.
