Replacing the system board

Use this information to install the system board.

Note
  1. Before you replace the system board, make sure that you backup any features on demand (FoD) keys that were enabled. Remember to re-enable the features on demand (FoD) keys after installing the new system board. For more information on Features on Demand (FoD), including instructions for automating the activation and installation of the activation key by using ToolsCenter or Systems Director, see the Features on Demand User's Guide at the Lenovo Features on Demand website under the Help section.
  2. When you reassemble the components in the server, be sure to route all cables carefully so that they are not exposed to excessive pressure and so that they do not get pinched when you reinstall the system board. In addition, make sure the cables are inserted into the relevant cable clips.
  3. When you replace the system board, you must either update the server with the latest firmware or restore the pre-existing firmware that the customer provides on 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.

Important: 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 in Safety and Installation guidelines.
  2. Slide the system board into the chassis with a small angle toward to the hard disk bays. Make sure the system board is seated into the chassis flat and the no standoff is blocking the system board.

  3. Push the edge of the external input/output connectors of the system board away from the hard disk bays.

  4. Make sure the eight standoffs are aligned with the corresponding captive screw holes on the system board.

  5. Align the screw holes on the system board with the screw holes on the chassis and install the screws to secure the system board to the chassis.

  6. Reconnect the cables that you disconnected earlier to the system board.
  7. Reinstall the DIMMs onto the system board (see Replacing a memory module).
  8. Reinstall the microprocessors and heat sinks (see Replacing a microprocessor and heat sink).
  9. Install the socket covers that you removed from the microprocessor sockets on the new system board and place them on the microprocessor sockets of the old system board, if you have not done so.
  10. Reconnect the SAS signal cables and remote RAID battery cable to the ServeRAID adapter, if you removed them earlier.
  11. Reinstall the PCI riser-card assemblies with the adapters, if any were installed (see Replacing a PCI riser-card assembly).
  12. Reinstall the air baffle (see Replacing the air baffle).
  13. Reinstall the cover (see Replacing the server top cover).
  14. Reconnect the power cords and any cables that you removed.
  15. Turn on the peripheral devices and the server.

Important: Perform the following updates:

  • Either update the server with the latest RAID firmware or restore the pre-existing firmware from a diskette or CD image.
  • Update the UUID (see Updating the Universal Unique Identifier (UUID)).
  • Update the DMI/SMBIOS (see Updating the DMI/SMBIOS data).
  • If you purchased a Feature on Demand, make sure that you reactivate the feature using the instructions in the Feature on Demand documentation.
