Replacing the system board

Note:
v 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.
v 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" on page 123, "Updating the Universal Unique Identifier (UUID)" on
