Note - The DDR3 DIMMs are customer-replaceable units (CRUs) and do not require an authorized service provider for replacement.
Faulty DIMMs are identified with a corresponding amber LED on the motherboard.
If the DIMM fault LED is off, the DIMM is operating properly.
If the DIMM fault LED is on (amber), the DIMM is faulty and should be replaced.
Figure 58 Identifying Faulty DIMMs
Rotate both DIMM socket ejectors outward as far as they will go.
The DIMM is partially ejected from the socket.
Carefully lift the DIMM straight up to remove it from the socket.

Note - With one exception, DIMM filler panels are optional and not required. The exception is processor 1 (P1) DIMM socket D7 in single-processor systems, which is required to support proper air flow for cooling.
