Chapter 7. Field replaceable units
This chapter describes the removal of field-replaceable server components.
Important: The field replaceable unit (FRU) procedures are intended for trained
servicers who are familiar with IBM products. See the parts listing in
“System” on page 94 to determine if the component being replaced is a
customer replaceable unit (CRU) or a FRU.

Complete the following steps to remove a microprocessor:
1. Shut down the operating system, turn off the blade server, and remove the
blade server from the BladeCenter unit (see “Removing the blade server from
the BladeCenter unit” on page 29).
2. Carefully lay the blade server on a flat, non-conductive surface.
3. Open the blade server cover (see “Opening the blade server cover” on page 34
for instructions).
4. Remove the bezel assembly (see “Removing the blade server bezel assembly”
on page 36 for instructions).
5. Identify the microprocessor to be removed.
Note: If you are replacing a failed microprocessor, verify that you have selected
the correct microprocessor for replacement (see “Light path diagnostics”
on page 75).
6. Remove the heat sink:
a. Loosen one captive screw fully; then, loosen the other captive screw.
Attention: Loosening one screw fully before loosening the other screw will
help to break the thermal bond that adheres the heat sink to the
microprocessor.
b. Gently pull the heat sink off of the microprocessor.
7. Rotate the locking lever on the microprocessor socket from its closed and
locked position until it stops or clicks in the fully open position (approximately
135° angle), as shown in Figure 28 on page 58.
