CAUTION:
The cell filler is required to be place in cells 3 – 6 in a four-processor configuration.
CAUTION:
Before starting this procedure, read the information about protecting against
electrostatic discharge (
“Preventing electrostatic discharge” (page 23)
).
CAUTION:
To prevent possible server malfunction and damage to the equipment, multiprocessor
configurations must contain processors with the same part number.
CAUTION:
All supported AMD Opteron quad-core processors 3.1 GHz or greater and all
supported AMD Opteron six-core processors require the system maintenance switch, located on
the I/O backplane, (SW1) position 5 to be in the On position.
HP recommends updating to the latest version of firmware. Earlier firmware versions might not
validate the required switch setting for these processors.
NOTE:
Six-core AMD Opteron Processors might show a 1 MB reduction in available L3 cache
when performance enhancing HT Assist is enabled because HT Assist requires 1MB of L3 cache
per CPU to operate.
To replace a processor:
1.
Power down the server (
“Power down the server” (page 25)
).
2.
Remove the processor memory cell (
“Processor memory cell” (page 29)
).
3.
Remove the processor memory cell airflow baffle (
“Processor memory cell airflow baffle”
WARNING!
