HP Integrity rx3600 Server User Service Guide

Removing and Replacing the Memory Carrier Assembly
The memory carrier assembly encloses the system DIMMs. There are two different memory carrier
assemblies available for this server:
• 8-DIMM memory carrier assembly
• 24-DIMM memory carrier assembly
The 8- and 24-DIMM memory carrier assemblies have two sides, 0 and 1, each of which contain
a memory board. System DIMMs seat onto the memory boards.
Table 73 lists the supported memory carrier assembly configurations.

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 removing and replacing the memory
carrier. Failure to follow ESD safety precautions can result in damage to the server.
Removing the Memory Carrier Assembly
To remove the memory carrier assembly, follow these steps:
1. Power off the server and disconnect the power cables. See “Powering Off the Server”
(page 82).
2. If rack installed, slide the server out from the rack until it stops. See “Extending the Server from
the Rack” (page 164).
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 167).
NOTE: You do not need to fully remove the top cover to service this component; however,
the top cover release lever must be open.
4. Press the button located in the center of the memory carrier assembly to release the extraction
handles (Figure 62).
CAUTION: Manipulate the extraction handles with care; failure to observe this caution can
result in damage to the extraction handles.
5. Pull up on the extraction handles, and rotate them outward approximately 90 degrees
(Figure 62).
NOTE: The extraction handles latch into the open position with an audible click.
