3. Install the bezel assembly (see "Installing the bezel assembly" on page 40). 4. Install the optional expansion unit, if you removed one from the blade server to replace the microprocessor and heat sink (see "Installing an optional expansion unit" on page 38). 5. Install the blade server cover (see "Installing the blade server cover" on page 36). 6. Install the blade server into the BladeCenter unit (see "Installing the blade server in a BladeCenter unit" on page 34). Removing the system-board assembly Use this information to remove the system-board assembly from the blade server. Attention: The system-board assembly is a field-replaceable unit (FRU) and must be replaced by a trained service technician. To contact an IBM service representative, see "Hardware service and support" on page 177. When you replace 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 10 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. Before you begin, read "Safety" on page v and "Installation guidelines" on page 31. 2. If the blade server is installed in a BladeCenter unit, remove it (see "Removing the blade server from the BladeCenter unit" on page 33 for instructions). 3. Carefully lay the blade server on a flat, static-protective surface. 4. Remove the blade server cover (see "Removing the blade server cover" on page 35). 5. If an optional expansion unit is installed, remove the expansion unit (see "Removing an optional expansion unit" on page 37). 6. Remove the blade server bezel assembly (see "Removing the bezel assembly" on page 39). 7. Remove all of the installed components in the following list from the system-board assembly; then, place them on a static-protective surface or install them on the new system-board assembly. v cKVM card.

Removing the system-board assembly
Use this information to remove the system-board assembly from the blade server.
Attention:
The system-board assembly is a field-replaceable unit (FRU) and must
be replaced by a trained service technician. To contact an IBM service
representative, see “Hardware service and support” on page 177.
When you replace 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 10 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.
Before you begin, read “Safety” on page v and “Installation guidelines” on
page 31.
2.
If the blade server is installed in a BladeCenter unit, remove it (see “Removing
the blade server from the BladeCenter unit” on page 33 for instructions).
3.
Carefully lay the blade server on a flat, static-protective surface.
4.
Remove the blade server cover (see “Removing the blade server cover” on page
35).
5.
If an optional expansion unit is installed, remove the expansion unit (see
“Removing an optional expansion unit” on page 37).
6.
Remove the blade server bezel assembly (see “Removing the bezel assembly”
on page 39).
7.
Remove all of the installed components in the following list from the
system-board assembly; then, place them on a static-protective surface or install
them on the new system-board assembly.
