Installing Memory Modules
You can increase the amount of memory in your server by installing memory
modules. Your server uses 168-pin, 3.3 volt, Error Correcting Code (ECC) dual
inline memory modules (DIMMs) to increase server memory.
You install memory modules into connectors inside the server. You can install up to
1024MB of ECC memory. (1MB equals approximately 1 000 000 bytes.) The
memory module sizes for your server include 256MB, 128MB, 64MB, 32MB, and
16MB. The available speed for these memory modules is 60 ns.
Before you begin:
Read “Safety Considerations” on page 4-2 and “Handling Static Sensitive
Devices” on page 4-3.
Remove the server and cover (see “Removing the Cover” on page 4-4).
Note: When installing memory modules, install the new modules into the first
available connector, starting at slot 4.
1. Locate the memory module connectors.
To locate the four memory module connectors, use the following figure:
2. Remove any adapters that are blocking the memory module connectors (see
“Removing Adapters” on page 4-26).
