FRU Removal and Replacement

Memory Modules

The position of the failing dual-inline memory modules (DIMMs) are reported by the
SROM power-up scripts ("Console Event Log," Chapter 2) or can be determined using the
procedures described with the memexer command (Chapter 3).
Note the following memory configuration rules when replacing memory:
•
At least one memory bank must contain a memory option.
•
A memory option consists of four DIMMs (0, 1, 2, and 3).
•
All DIMMs in a bank must be of the same capacity and part number.
STEP 1: RECORD THE POSITION OF THE FAILING DIMM.
STEP 2: LOCATE THE FAILING DIMM ON THE MOTHERBOARD.
STEP 3: REPLACE THE FAILING DIMMS.
