Processor option
The server supports up to four processors. With two or more processors installed, the server supports boot
functions through the processor installed in processor socket 1.
Server PPMs provide the proper power to each processor. Each PPM must be installed in the slot adjacent
to its processor.
CAUTION: To prevent thermal instability and damage to the server, do not separate the processor from the
heatsink. The processor, heatsink, and retaining clip make up a single assembly.
CAUTION: To prevent possible server malfunction, do not mix processors of different speeds or cache
sizes. Refer to the label on the processor heatsink for a description of the processor.
IMPORTANT: Populate the processors in the following order: 1, 2, 4, 3.
IMPORTANT: If upgrading processor speed or adding additional processors, update the system ROM
before installing the processor.
IMPORTANT: Processor socket 1 and PPM slot 1 must be populated at all times or the server does not
function.
IMPORTANT: Always install a PPM when you install a processor. The system fails to boot if the PPM is
missing.
IMPORTANT: To ensure proper cooling, be sure the processor baffle is installed at all times.
To install a processor:
1. Power down the server (on page 23 ).
2. Do one of the following:
— Unlock and remove the bezel ("
Unlock and remove the tower bezel " on page 25 ).
— Extend the server from the rack (on page 23 ).
3. Remove the access panel (on page 27 ).
