Processor options
The server supports up to four processors.
Observe the following processor installation guidelines:
• Processor socket 1 must be populated.
• HP recommends installing processors in pairs.
When configuring the server, see the following table to determine which processors must be populated to
ensure which expansion slots can be used.
Processor Expansion slots
1 Expansion slots 10 and 11
2 Expansion slots 7–9
3 Expansion slots 4–6
4 Expansion slots 1–3
Installing a processor option
The processors and memory are stored in a module at the front of the server. Access to the processor
memory module is provided through the front panel, eliminating the need to extend the server from the
rack to install new or replace existing processors or upgrade the memory.
WARNING: Use caution when installing the processor memory module or removing the
processor memory module. The processor memory module is very heavy when fully
populated.
CAUTION: To help avoid damage to the processor and system board, do not install the
processor without using the processor installation tool.
CAUTION: To prevent possible server malfunction and damage to the equipment,
multiprocessor configurations must contain processors with the same part number.
IMPORTANT: When either optional I/O expansion board is installed in a two-processor
configuration, processor 2 and the I/O enabler must be installed.
To install the component:
1. Update the system ROM.
Locate and download the latest ROM version from the HP website (http://www.hp.com/support
).
Follow the instructions on the website to update the system ROM.
2. Power down the server (on page 25).
3. Remove the processor memory drawer (on page 27).
CAUTION: To prevent damage to the processor memory drawer cover, be sure the handle of
the processor memory drawer is fully open before removing the cover.
