DIMM Population Scenarios
Note - In single-processor systems, the DIMM slots associated with processor 1 (P1) are
nonfunctional and should not be populated with DIMMs.

DIMM Population Scenarios
There are two scenarios in which you are required to populate DIMMs:
■
A DIMM fails and needs to be replaced.
In this scenario, you can use the Fault Remind button to determine the failed DIMM, then
remove the failed DIMM and replace it. To ensure that system performance is maintained,
you must replace the failed DIMM with a DIMM of the same size (in gigabytes) and type
(quad-rank or dual-rank). In this scenario, you should not change the DIMM configuration.
