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.
The server PPMs are DC-to-DC converters that provide the proper power to each processor. Each PPM
must be installed in the slot adjacent to its processor.
CAUTION: Always wear an antistatic wrist strap when working inside the server.
CAUTION: To prevent possible server malfunction, do not mix processors of different types.
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.
IMPORTANT: Always install a PPM when you install a processor. The system fails to boot if the PPM is
missing.
