Chapter 4 Removing and Replacing Cold-Swappable Components 83
Removing a Memory Module
If a memory module (DIMM) fails, POST diagnostics alerts ALOM to light the
enclosure status Service Required LED.
Caution – DIMMs are made of electronic components that are extremely sensitive
to static electricity. Static electricity from your clothes or work environment can
destroy the DIMM. Do not remove a DIMM from its antistatic packaging until you
are ready to install it on the CPU/memory module. Handle the DIMM only by its
edges. Do not touch the components or any metal part. Always wear an antistatic
grounding strap when you handle the DIMM. For more information, see
“Avoiding
Electrostatic Discharge” on page 32 .
Caution –
The CPU/memory module and the DIMMs can be hot. Handle the
CPU/memory module and the DIMMs carefully to avoid injury.
1. Power off the system.
See “Powering Off the System” on page 26 .
2. Attach the antistatic wrist strap.
See “Avoiding Electrostatic Discharge” on page 32 .
3. Remove the top cover.
See “Removing the Top Cover” on page 30 .
4. Remove the appropriate CPU/memory module from the system.
See “Removing a CPU/Memory Module” on page 77 .
5. Identify the memory module to be removed.
