Replacing the system board

Use this information to replace the system board.

Attention
  1. When you reassemble the components in the server, be sure to route all cables carefully so that they are not exposed to excessive pressure.
  2. Before removing any components or disconnecting any cables, keep note of their respective locations and how they are connected to the system board.
  3. When you replace the system board, you must either update the server with the latest firmware or restore the pre-existing firmware from a diskette or CD image. Make sure that you have the latest firmware or a copy of the pre-existing firmware before you proceed. See Updating the firmware, Updating the Universal Unique Identifier (UUID), and Updating the DMI/SMBIOS data for more information.
  4. When you replace the system board, make sure that you remove the Integrated Management Module Advanced Upgrade and place it on the new system board. For information about the Advanced Upgrade, see Using the remote presence and blue-screen capture features.
  5. Reactivate any Features on Demand features. Instructions for automating the activation of features and installing activation keys is in the IBM Features on Demand User's Guide. To download the document, go to the Lenovo Features on Demand website, log in, and click Help.
  6. Some cluster solutions require specific code levels or coordinated code updates. If the device is part of a cluster solution, verify that the latest level of code is supported for the cluster solution before you update the code.

To install the system board, complete the following steps:

  1. Read the safety information that begins on Safety, Handling static-sensitive devices, and Installation guidelines.
  2. Align the system board at an angle, as shown in the illustration; then, rotate and lower it flat and slide it back toward the rear of the server. Make sure that the rear connectors extend through the rear of the chassis.

  3. Reconnect to the system board the cables that you disconnected. See Internal cable routing and connectors.
  4. Rotate the system-board thumbscrews toward the rear of the server until the latch clicks into place.
  5. Install the fan bracket (see Replacing the fan bracket).
  6. Install the hot-swap fans (see Replacing a hot-swap fan).
    Note
    Remember to insert the hot-swap drive backplane cables in between the hot-swap fans as shown in the illustration. Do not leave the cables on top of the hot-swap fans.

  7. Install the system battery (see Replacing the system battery).
  8. (Trained technician only) Install the microprocessor and heat sink (see Replacing a microprocessor and heat sink).
  9. Install the USB embedded hypervisor flash device (see Replacing a USB embedded hypervisor flash device).
  10. Install the memory modules (see Installing a memory module).
  11. Install the ServeRAID memory module (see Replacing the ServeRAID adapter memory module).
  12. Install the dual-port network adapter (see Replacing the dual-port network adapter).
  13. Install the air baffle (see Replacing the air baffle).
  14. Install the PCI riser-card assemblies and adapters, if any were installed (see Replacing an adapter and Replacing a PCI riser-card assembly).
  15. Install the rear two hard-disk-drive kit, if any (see Replacing the rear two hard-disk-drive kit).
  16. Install the cover (see Replacing the cover).
  17. Push the power supplies back into the server.
  18. Slide the server into the rack.
  19. Reconnect the power cords and any cables that you removed.
  20. Turn on the peripheral devices and the server.
  21. Start the Setup utility and reset the configuration.
    • Set the system date and time.
    • Set the power-on password.
    • Reconfigure the server.
    See Using the Setup utility for more details.
  22. Either update the server with the latest RAID firmware or restore the pre-existing firmware from a diskette or CD image.
  23. Update the UUID (see Updating the Universal Unique Identifier (UUID)).
  24. Update the DMI/SMBIOS (see Updating the DMI/SMBIOS data).
  25. Reactivate any Features on Demand features.
