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 that the customer
provides on a diskette or CD image. The vital product data (VPD) must also be
updated. Make sure that you have the latest firmware or a copy of the
pre-existing firmware before you proceed. See “Updating the firmware” on
page 93 and (see “Updating the DMI/SMBIOS data” on page 116) for more
information.
Attention: Installing the wrong firmware or device-driver update might cause
the server to malfunction. Before you install a firmware or device-driver
update, read any readme and change history files that are provided with the
downloaded update. These files contain important information about the
update and the procedure for installing the update, including any special
procedure for updating from an early firmware or device-driver version to the
latest version.

code is supported for the cluster solution before you update the code
