Processor Option - HP ProLiant DL385 User Manual

58 HP ProLiant DL385 Server User Guide

Processor option

The server supports single- and dual-processor operation. With two processors
installed, the server supports boot functions through the processor installed in
processor socket 1.
The server PPMs are DC-to-DC converters that provide the proper power to each
processor. Each PPM must be installed in the slot adjacent to its processor.
To install a processor:
1. Power down the server ("Powering down the server" on page 35).
2. Extend the server from the rack, if applicable ("Extending the server from the
rack" on page 37).
3. Remove the access panel.
CAUTION: Always wear an antistatic wrist strap when working
inside the server.
CAUTION: To prevent possible server malfunction, do not mix
processors of different types.
IMPORTANT: If upgrading processor speed, 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 will not function properly.
IMPORTANT: Always install a PPM when you install a processor. The
system fails to boot if the PPM is missing.
