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 the 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 21 lists the supported memory carrier assembly configurations.

Memory Boards InstalledMemory Carrier Configuration

Two 12-DIMM memory boards24-DIMM memory carrier
WARNING! Ensure that the system is powered off and all power sources have been disconnected
from the server prior to moving DIMMs.
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 the Memory Carrier Assembly
To remove the memory carrier assembly, follow these steps:
1. Unlatch the cover release lever on the top cover and remove the memory carrier assembly
cover. See “Removing the Memory Carrier Assembly Cover” (page 46).
NOTE: You do not need to fully remove the top cover to service this component; however,
the top cover release lever must be open.
2. Press the button located in the center of the memory carrier assembly to release the extraction
handles (Figure 21).
CAUTION: Manipulate the extraction handles with care. Failure to observe this caution can
result in damage to the extraction handles.
3. Pull up on the extraction handles and rotate them outward 90 degrees (Figure 21). The handles
latch into the open position with an audible click.
4. Lift the memory carrier assembly out of the chassis (Figure 21).
NOTE: To avoid damage to the handles, HP recommends rotating the handles inward and
snapping them into place when servicing the system DIMMs, or any time the carrier is out of
the chassis. Before replacing the memory carrier, press the button to release the extraction
handles. Use the handles to replace the memory carrier into the chassis.
