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.
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 will attempt to boot from processor 2 and provide a processor failure message.
The server uses PPMs to provide power to each processor. The corresponding PPM must be installed for
each processor or the system cannot boot.
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 single- and
dual-core processors or processors with different speeds or cache sizes.
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 does not
function properly.
