v
There must be at least one memory card with one pair of DIMMs installed for the
server to operate.
v When you install additional DIMMs on a memory card, be sure to install them in
pairs. All the DIMM pairs on each memory card must be of the same size and
type.
v
Add odd-numbered DIMMs to each available memory card first, and then add the
even-numbered pairs.
v
Install the DIMMs on each memory card in the order shown in the following table.
Each memory card must have at least one pair of DIMMs. See the User’s Guide
on the IBM Documentation CD for additional memory configuration installation
sequences.

If memory mirroring is enabled, you can hot-replace one memory card at a time
on each memory power bus.
If a problem with a DIMM is detected, light path diagnostics will light the
system-error LED on the front of the server, indicating that there is a problem
and guide you to the defective DIMM. When this occurs, first identify the
defective DIMM; then, remove and replace the DIMM.
The following illustration shows the LEDs on the memory card.
