Removing the system board assembly
When replacing the system board, you will replace the system board and blade
base as one assembly. After replacement, you must either update the blade server
with the latest firmware or restore the pre-existing firmware that the customer
provides on a diskette or CD image.
Note: See “System board layouts” on page 7 for more information on the locations
of the connectors, jumpers and LEDs on the system board.
To remove the system board assembly, complete the following steps:
1. Read the safety information that begins on page vii, and “Installation guidelines”
on page 75.
2. If the blade server is installed in a BladeCenter unit, remove it (see “Removing
the blade server from a BladeCenter unit” on page 77 for instructions).
3. Remove the blade server cover (see “Removing the blade server cover” on
page 80).
4. If a Memory and I/O Expansion Blade is installed, remove it (see “Removing an
expansion unit” on page 82).
5. If a Memory and I/O Expansion Blade is not installed, remove the power jumper
(see “Removing the power jumper” on page 99).
6. Remove the blade server bezel assembly (see “Removing the bezel assembly”
on page 84).
7. Remove all of the installed components in the following list from the system
board assembly; then, place them on a non-conductive surface or install them
on the new system board assembly.
