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
workstation 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 13.
2. If the blade workstation is installed in a BladeCenter unit, remove it (see
“Removing the blade workstation from a BladeCenter unit” on page 16 for
instructions).
3. Remove the blade workstation cover (see “Removing the blade workstation
cover” on page 19).
4. Remove the blade workstation bezel assembly (see “Removing the bezel
assembly” on page 21).
5. 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.
