Chapter 4 Removing and Replacing Cold-Swappable Components 85
Installing a Memory Module
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. Locate the slot into which you are installing the memory module.
2. Rotate out the memory module ejector levers for that slot.
3. Holding the bottom edge of the module parallel to its socket, carefully align the
module so that each of its contacts is centered on a socket pin.
Ensure that the memory module is correctly oriented. A notch along the bottom of
the memory module corresponds to a tab on the socket.
4. Push firmly and evenly on both ends of the memory module until its bottom edge
is firmly seated in the socket.
You hear a click when the ejector levers lock into place.
5. Repeat Step 1 through Step 4 for all memory modules to be installed.
6. Install the CPU/memory module back into the system.
See “Installing a CPU/Memory Module” on page 80 .
7. Replace the top cover.
See “Installing the Top Cover” on page 31 .
8. Power on the system.
See “Powering On the System” on page 22 .
