Installing a processor in HP ProLiant ML150 Generation 3 and
Generation 5 Servers
HP ProLiant ML150 Generation 3 and Generation 5 Servers support 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 embedded PPMs as DC-to-DC converters to provide the proper power to each processor.
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:
Processor socket 1 must be populated at all times or the server does not function.
To install a processor:
1.
Power down the server (on page

).
2.
Extend the server from the rack.
3.
Remove the access panel ("
