Chapter 7
Installing Additional Processors
76
l
Use only HP recommended processor modules for the HP NetServer
LXr 8500.
l
Additional processors must match existing processor module or be
changed. It is not acceptable to mix processor modules (Pentium II or III)
with various speeds, cache sizes, and product numbers. Your HP reseller
can advise you about matching processor modules. See Figures 7-4 and 7-5
for the appropriate jumper settings.
l
Use processor expansion kits with the same HP product number when
installing more than one processor module. This ensures the same
processor type, clock speed and cache size.
l
The HP NetServer LXr 8500 does not require additional voltage regulator
modules (VRMs) when adding additional processors. The processor
boards have the required VRMS installed on the board.
NOTE
Before installing additional processors, you must first
determine the slot availability for processor installation. Refer
to Tables 7-1 and 7-2 for processor requirements.
