Identify and Remove Faulty DIMMs
- Prepare the server for service.
- If there are full-length PCIe2 cards installed in PCIe slots 4 and 5, remove the PCI mezzanine, if necessary.
- Remove the air duct.
See Remove the Air Duct.
- When removing DIMMs from slots D4 through D8 next to CPU P0, remove the media bay assembly.
- Press the
fault remind
button on the motherboard
to
identify
the location of the faulty DIMMs.
- Note the location of faulty DIMMs.
Faulty DIMMs are identified when a corresponding amber service action required LED lights next to the DIMM.
If the DIMM service action required LED is off: DIMM is operating properly.
If the DIMM service action required LED is on (amber): DIMM is faulty and should be replaced.

- Remove the faulty DIMM by rotating
both DIMM slot ejectors outward until the DIMM partially ejects
from its socket.
Carefully lift the DIMM out of its socket.

- Replace each faulty DIMM with
either another DIMM of the same rank size (quad rank, dual rank,
or single rank) or a DIMM filler panel.
For DIMM replacement instructions, see Install DIMMs.
Caution - If you are not immediately inserting a replacement DIMM into the empty DIMM socket, you should insert a DIMM filler panel in the socket to ensure adequate cooling and reduce the possibility of a system shutdown.
