Replacing the system board

Use this information to replace the system board.

Note

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. 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.
3. When you replace the system board, make sure that you remove the Integrated Management Module II (IMM2) 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
4. Reactivate any Features on Demand features after replacing the system board. Instructions for automating the activation of features and installing activation keys is in the Features on Demand User's Guide. To download the document, go to the Lenovo Features on Demand website, log in, and click Help.
5. 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.

Read the safety information in Safety and Installation guidelines.

If you are replacing a server component in the server, you need to slide the server out from the rack enclosure, turn off the server and peripheral devices, and disconnect the power cords and all external cables.

To replace the system board, complete the following steps.

1. Touch the static-protective package that contains the system board to any unpainted metal surface on the server; then, remove the system board from the package.
   Note

   When you are holding or replacing the system board in the server, avoid touching the cable clips on the side of the chassis and the connectors on the system board. Be careful not to damage any surrounding components inside the chassis.
2. Align the system board with the chassis and replace the nine screws that you removed.

3. Install any of the following components that you removed from the system board:
   Note

   Make sure that none of the server cables are caught under the system board.

   • Microprocessor and heat sink (see Replacing a microprocessor and heat sink)
   • DIMMs (see Installing a DIMM)
   • Adapters (see Replacing an adapter)
   • Remote RAID battery holder (see Replacing the RAID adapter battery or flash power module holder)
4. Reconnect any cables to the system board that you disconnected during removal (see System-board internal connectors and Internal cable routing and connectors).
5. Reinstall the PCI riser-card assembly (see Replacing the PCI riser-card assembly).
6. Reinstall the air baffle (see Replacing the air baffle).
7. Reinstall the cover (see Replacing the cover).
8. Slide the server into the rack.
9. Reconnect the external cables and power cords; then, turn on the attached devices and turn on the server.
10. Start the Setup utility and reset the configuration.
    1. Set the system date and time.
    2. Set the power-on password.
    3. Reconfigure the server.

    See Using the Setup utility for details.

11. Either update the server with the latest RAID firmware or restore the pre-existing firmware from a diskette or CD image.
12. Update the UUID (see Updating the Universal Unique Identifier (UUID)).
13. Update the DMI/SMBIOS (see Updating the DMI/SMBIOS data).
14. Reactivate any Features on Demand features.
