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 227.
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 14 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 49.
2. If the blade server is installed in a BladeCenter unit, remove it (see “Removing
the blade server from the BladeCenter unit” on page 52 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
55).
5.
If an optional expansion unit is installed, remove the expansion unit (see
“Removing an optional expansion unit” on page 57).
6. Remove all of the installed components in the following list from the
system-board assembly; then, place them on a static-protective surface or
immediately install them on the new system-board assembly.

Microprocessors and heat sinks. See “Removing a microprocessor and heat
sink” on page 85.
7.
Remove the dust cover over the microprocessor sockets of the new
system-board assembly and place them over the microprocessor sockets of the
old system-board assembly (see “System-board layouts” on page 14).

instructions, and use any packaging materials for shipping that are supplied to
you.
