46 HP ProLiant ML350 Generation 4p 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. However, if processor 1 fails, the system automatically boots
from processor 2 and provides a processor failure message.
The server uses PPMs as DC-to-DC converters to provide the proper power to
each processor. Processor 1 uses an embedded PPM. Processor 2 uses a PPM that
must be installed in the adjacent slot.
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 and
damage to the equipment, do not mix processors of different types.
IMPORTANT: If upgrading processor speed, update the system ROM
before installing the processor.
IMPORTANT: PPM 2 must be installed when processor 2 is installed.
The system fails to boot if the PPM is missing.
To install a processor:
1. Power down the server ("Powering Down the Server" on page 25 ).
2. Extend the server from the rack, if applicable ("Extending the Server from
the Rack" on page 26 ).
3. Remove the front bezel, if necessary ("Removing the Front Bezel (Tower
Model)" on page 27 ).
4. Remove the access panel ("Removing Access Panel" on page 27 ).
5. Open the processor locking lever.
