Installing/Removing Memory Modules 8–3
Publication 6181-UM001D-EN-P
Internal RAC6181 Computer components may be damaged by
Electrostatic Discharge (ESD). Make sure you wear a grounding strap
whenever handling circuit boards, memory modules or other internal
components.
ATTENTION: Wear a wrist strap (well grounded) and
perform work in a static-safe environment. Electrostatic
discharge can damage the RAC6181 Computer and
components.
Also observe the following precautions:
•
Always handle the memory cards by the ends not by the memory
module contacts.
•
Store memory in a sealed anti–static bag when it is not installed.
•
Never install or remove memory with the power turned on.
This section gives instructions on how to change an installed memory
module in the RAC6181 Pentium processor board. These instructions
also apply to changing SODIMM memory on the 6181 Pentium III
processor board.
To add or remove memory:
1. Disconnect power from the RAC6181 Computer.
ATTENTION: Disconnect all power from the RAC6181
Computer before adding/removing components. Failure
to disconnect power could result in severe electrical shock
or damage to the RAC6181 Computer.
2. Remove the top cover of the RAC6181 Computer. Refer to
“Removing the Back Cover and Top Cover” on page 4-3 for
instructions.
Important : If you have a 2-slot chassis with a Pentium III CPU, you
must remove the CPU card to install SODIMM memory
modules. Refer to “Adding/Removing CPU and Add-in
Cards” on page 4-4 for complete instructions.
3. The memory module is located at the top of the CPU card, just
below the top cover. Remove the existing memory module from the
CPU card.
a. DIMM modules: remove by pressing down on the retaining
latch.
b. SODIMM modules: remove by pulling the edges of the
connector away from the SODIMM until the SODIMM pops up.
