HP ProLiant DL560 Server User Guide
The server uses Processor Power Modules (PPMs) as DC-to-DC converters to
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: If upgrading processor speed, update the system ROM
before installing the processor.
IMPORTANT: Always install a PPM when you install a processor. The
system fails to boot if the PPM is missing.
IMPORTANT: Processor socket 1 and PPM slot 1 must be populated
at all times or the server will not function properly.
To install a processor:
1. Power down the server ("Powering Down the Server" on page 29).
2. Extend the server from the rack, if applicable ("Extending the Server from
3. Remove the access panel ("Removing the Access Panel" on page 32).
