6.
If rack installed, slide the server completely into the rack. See
“Inserting the Server into the
Rack” (page 177)
.
7.
Reconnect the power cables and power on the server. See
“Powering On the Server” (page 90)
.
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
“Powering Off the Server”
(page 90)
.
2.
If rack installed, slide the server out from the rack until it stops. See
“Extending the Server from
the Rack” (page 176)
.
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”
(page 203)
.
NOTE:
To avoid damage to the extraction handles, HP 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
Figure 70: “48-DIMM Memory Carrier Board Slot
IDs”
,.
6.
Lay the memory carrier assembly on side 0 or side 1 so that the memory board containing
the DIMMs that require servicing faces upward (
Figure 68
).
7.
Remove the memory carrier assembly side cover.
a.
Press the release tabs (
Figure 68
) on both sides of the extraction handle release button
until the side cover releases from the top center of the assembly.
b.
Rotate the side cover slightly to free the tabs from the retaining slots at the base of the
assembly (
Figure 69
).
c.
Lift the side cover off the assembly.
