Hardware options installation
Introduction
If more than one option is being installed, read the installation instructions for all the hardware options
and identify similar steps to streamline the installation process.
WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives and the
internal system components to cool before touching them.
CAUTION: To prevent damage to electrical components, properly ground the server before
beginning any installation procedure. Improper grounding can cause electrostatic discharge.
Review "Electrostatic Discharge (on page 110)" before installing hardware options into the server.
Processor options
The server supports up to four processors. Observe the following processor installation guidelines:
• Processor socket 1 must be populated at all times so that the server functions properly.
• Processors must be installed in the following order: processor 1, processor 2, processor 3, and
processor 4.
• When either optional I/O expansion board in installed in a two-processor configuration, the second
processor must be installed in socket 3.
Installing a processor
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: If installing a processor with a faster speed, update the system ROM before
installing the processor.
