System Memory DIMMs
System memory DIMMs are located on the memory extender board.
WARNING
Ensure that the system is powered down and all power sources have been
disconnected from the server prior to removing or replacing system memory 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 could result in personal injury or damage to
equipment.
CAUTION
Observe all ESD safety precautions before attempting this procedure. Failure to follow ESD
safety precautions could result in damage to the server.
Removing System Memory DIMMs
To remove system memory, perform the following steps:
Step 1. If rack mounted, slide the HP Server out from the rack until it stops. (Refer to the hp9000 rp4440
Installation Guide for additional information.)
NOTE
If desired, the processor extender board may be removed without removing the HP
Server from the rack.
Step 2. Remove the front bezel. (Refer to “Front Bezel” on page 38.)
Step 3. Remove the front cover. (Refer to “Front and Top Covers” on page 39.)
Step 4. Remove the memory extender board. (Refer to “Memory Extender Board” on page 45.)
Step 5. Identify the DIMM to be removed and push the appropriate extraction levers found on either side of
the DIMM slot outward to the open position. The DIMM will eject from the slot.
Step 6. Remove the DIMM from the socket.
Installing Memory DIMMs
Your hp 9000 rp4440 Server comes with a sixteen DIMM memory extender board that is minimally
configured with 1 GB of memory [four 256 MB DIMMs loaded in quad 0 (slots 0A,0B,0C,and 0D)]. See
Figure 4-9, “16 DIMM Extender Board Slot IDs.”
An optional thirty-two DIMM memory extender board is available to replace the sixteen DIMM memory
extender board and must also be minimally configured with 1 GB in quad 0. See Figure 4-10, “32 DIMM
Extender Board Slot IDs.”
You may insert additional DIMMs into both sixteen and thirty-two DIMM boards. When adding DIMMs, you
must use a minimum of four like sized DIMMs in the next available quad.
