HP Rp3440-4 - 9000 - 0 MB RAM Installation Manual page 49

In order to use the chip spare functionality, only DIMMs built with x4 SDRAM parts can be used, and these
DIMMs must be loaded in quads (two DIMMs per memory cell, loaded in the same location in each memory
cell).
System Firmware Requirements
If you are using 4 GB DIMMs in a HP 9000 rp3440 server, system firmware must be greater than revision
44.24. Use the BCH FV command, or the iLO MP SR command to display the system firmware revision status.
If necessary, use the iLO MP SR command to upgrade system firmware. (Detailed instructions are downloaded
with the upgrade.)
Installation Procedure
To install DIMMs, follow these steps:
Step 1. Power off the server and disconnect all power and external cables.
Step 2. Remove the server cover. (See "Removing and Replacing Server Covers and Bezels" on page 25.)
Step 3. Remove the memory airflow guide. (See "Removing the Memory Airflow Guide" on page 41.)
CAUTION
Step 4. Locate the slot into which the DIMM will be installed. Holding the memory module by its left and
right edges, insert the module into the socket (Figure 1-36.)
NOTE
Step 5. Evenly push down firmly on each end of the DIMM until it seats in the socket. Ensure the
extraction levers are in the closed position.
Chapter 1
To ensure that memory modules are not damaged during removal or installation,
power off the server and unplug the power cord from the ac power outlet. Wait until
the LED on the back of the power supply turns off before removing or installing
memory.
The memory modules are keyed and can only be inserted in one direction. When the
module is correctly seated, the retainer clips will return to their fully upright
position. Snap the clips firmly into place to ensure that the DIMMs are seated
properly.
