Removing and Replacing a Memory Module
The server comes with a single memory module installed in the primary (MEM 1) slot. The memory
module supports up to 384 MB of memory, a 64-bit memory interface, and 2-way interleaving. The
server’s overall performance can be increased by adding memory to the existing memory module or by
installing an additional memory module in the memory expansion (MEM 2) slot. Adding a second
memory module enables the server to support up to 768 MB of memory.
NOTE
Due to height limitations, do not install SIMMs taller than one inch. Installing SIMMs
taller than one inch can interfere with an adjacent CPU module or memory module.
Also, make sure to completely fill the primary memory module (MEM 1 slot) before
installing a second memory module in the memory expansion (MEM 2 slot).
The following procedure can be used to remove and replace any memory module.
1) Turn off the server.
2) Disconnect external devices, ac power, and monitor power.
3) Unlock and remove left side panel.
4) Remove memory module retaining bracket.
5) Carefully remove memory module from main logic board and place it on an antistatic surface.
6) Add additional server memory onto existing memory module.
Refer to
“Installing Additional Server Memory”
for more information.
7) Replace memory module and secure with retaining bracket.
8) Replace and lock left side panel.
9) Connect external devices and restore power.
10) Run the SCU to configure the server for the additional amount of memory.
