Removing the system-board assembly - BladeCenter HX5
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
279.
When you replace the system board, you 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.
Note: See "System board layouts" on page 12 for more information about the locations of the connectors,
jumpers, and LEDs on the system board.
To remove the system-board assembly, complete the following steps:
Step 1.
Before you begin, read "Safety" on page v and "Installation guidelines" on page 65.
Step 2.
If the blade server is installed in a BladeCenter chassis, remove it (see "Removing the blade server
from the BladeCenter chassis" on page 66 for instructions).
Step 3.
Carefully lay the blade server on a flat, static-protective surface.
Step 4.
If an optional expansion unit is installed, remove the expansion unit (see "Removing an expansion
unit" on page 96 for instructions).
Note: Optional expansion units are not supported when a IBM MAX5 expansion blade is installed.
Step 5.
If you are removing the system-board assembly from a blade server that is the bottom blade server
in a scalable blade complex, disassemble the blade complex (see "Disassembling a scalable blade
complex" on page 68 for instructions).
Step 6.
If an IBM MAX5 expansion blade is installed, remove it (see "Removing an IBM MAX5 expansion
blade" on page 87 for instructions).
Step 7.
Open the blade server cover (see "Removing the blade server cover" on page 71 for instructions).
Step 8.
Remove the access panel if you have the standard heat sinks installed.
Note: If you have the tall heat sinks installed, you do not need to remove the access panel.
