Step 5.
At the same time, push the appropriate extraction levers found on either side of the DIMM
connector outward to the open position. The DIMM ejects from the connector.
Step 6.
Remove the DIMM from the socket. If the removed memory is functional, store it in a static-free
container for future use.
Installing System Memory
Memory modules must be loaded in the correct order:
•
In the HP 9000 rp3410 server, the first four DIMMs must be installed as ordered pairs of equal size. The
DIMM in socket 0A must match the DIMM in socket 0B. If a second pair is added (sockets 1A and 1B), the
DIMMs must match the DIMMs in sockets 0A and 0B. Additional DIMMs (DIMM sockets 5 through 12)
must be installed as quads (identical groups of four—two matched pairs). This requirement is
summarized as:
•
0A and 0B must be an identical pair
•
1A and 1B must be identical to the pair in sockets 0A and 0B
•
2A, 2B and 3A, 3B must be an identical quad (2 pairs)
•
4A, 4B and 5A, 5B must be an identical quad (2 pairs)
•
In the HP 9000 rp3440 server, DIMMs must be installed in matched quads. Two matched memory card
pairs of equal size (that is, four identical DIMMs) must be installed, one pair per memory cell, as listed
below:
•
0A, 0B and 1A, 1B must be an identical quad (2 pairs)
•
2A, 2B and 3A, 3B must be an identical quad (2 pairs)
•
4A, 4B and 5A, 5B must be an identical quad (2 pairs)
NOTE
DIMMs match if they have the same HP part number.
Module sizes can be mixed, as long as DIMMs in each quad match. For example:
•
On HP 9000 rp3410 servers, it is acceptable to load four 256 MB DIMMs in sockets 0A, 0B, 1A, and 1B
and four 512 MB or 1 GB DIMMs in sockets 2A, 2B, 3A, and 3B
•
On HP 9000 rp3440 servers, it is acceptable to load a quad of 256 MB DIMMs in sockets 0A, 0B, 1A and
1B, and a quad of larger DIMMs in sockets 2A, 2B, 3A and 3B
To install DIMMs, follow these steps:
Step 1.
Power off the server and disconnect power and external cables.
CAUTION
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.
Step 2.
Remove the top cover.
Step 3.
Remove the memory airflow guide. (See “Removing the Memory Airflow Guide” on page 171.)
