Removal and Replacement

5.2.4 CPU and Memory Modules

Perform the following procedure to remove CPU or memory modules:
Before performing the following removal and replacement
procedures, switch off the circuit breakers on the back of the
LSB chassis and on the power controller.
Special instructions apply to extend the LSB chassis to prevent
personal injury (see Section 5.2.2).
1. Extend the LSB chassis for service (see Section 5.2.2).
2. Remove the top cover (see Section 5.2.3).
3. Put on an antistatic wriststrap.
An antistatic wriststrap must be worn when handling any module
to prevent damage to the module.
4. On the module being removed, pull the two black restraining clips up and to
the left (see Figure 5–4 (1) ). The clips snap when they open.
5. Pull both levers up at the same time until they are perpendicular to the top of
the module (see Figure 5–4 (2) ). This frees the module from the backplane.
6. Holding the levers, pull up on the module until it is out far enough to be able
to hold it underneath as it is removed.
7. When the module is free of the card cage, place it on an ESD pad in a safe
area, or pack it in the box that the new module was shipped in.
To replace a CPU or memory module, align the tracks of the module with the
tracks in the card cage slot and reverse steps 1 through 7.
