HP 9000 rp5400 Servers - Manual (Page 123)

Processor Support Module Replacement
Processor Support Modules (PSMs) (there can be two PSMs, numbered 0 and 1) reside on the
System Board and are accessed via the Top Service Bay. Looking into the Top Service Bay from
the front, PSMs are located on either side of the server, at the front.
To replace a PSM, perform the following steps:
1. Seat the PSM into its socket.
2. Tighten the two captive mounting screws that hold the PSM in place.
NOTE: For the rp5470, the mounting screws have been replaced by posts and the air baffle
is used to secure the PSM's.
The following graphic shows a PSM in the server.
Memory DIMM Removal
Memory DIMMs reside in slots (up to eight) located on the System Board. They are loaded in
DIMM pairs of equal size.
