Reconnect the power cables and power on the server. See
Removing and Replacing System Memory
System memory, or DIMMs, are located on a pair of memory boards inside the memory carrier
assembly.
WARNING!
Ensure that the system is powered off and all power sources have been
disconnected from the server prior to performing this procedure.
Voltages are present at various locations within the server whenever an AC power source is
connected. This voltage is present even when the main power switch is in the off position.
Failure to observe this warning can result in personal injury or damage to equipment.
CAUTION:
Observe all ESD safety precautions before attempting this procedure. Failure to
follow ESD safety precautions can result in damage to the server.
Removing System Memory
To remove system memory, follow these steps:
1.
Power off the server and disconnect the power cables. See
2.
If rack installed, slide the server out from the rack until it stops. See

3.
Unlatch the cover release lever on the top cover and remove the memory carrier assembly
cover. See
“Removing the Memory Carrier Assembly Cover” (page 179)
.
NOTE:
You do not need to fully remove the top cover to service this component; however,
the top cover release lever must be open. You must remove the memory carrier because it
attaches directly to the processor board.
4.
Remove the memory carrier assembly. See
“Removing the Memory Carrier Assembly”
NOTE:
To avoid damage to the extraction handles, Hewlett Packard Enterprise
recommends rotating the handles inward and snapping them into the locked position when
servicing the system DIMMs or any time the carrier is out of the chassis. Before replacing
the memory carrier assembly, press the button to release the extraction handles. Use the
handles to replace the memory carrier into the chassis.
5.
Locate the DIMM you need to remove. Use
