Introduction
If you plan to install more than one hardware option, 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 Chapter 9 (page 93) before installing hardware options into the server.
Processor options
The server supports a four- or eight-processor configuration.
CAUTION: The cell filler is required in cells 3 – 6 in a four-processor configuration.
CAUTION: All supported AMD Opteron quad-core processors 3.1 GHz or greater and all
supported AMD Opteron six-core processors require the system maintenance switch, located on
the I/O backplane, (SW1) position 5 to be in the On position.
HP recommends updating to the latest version of firmware. Earlier firmware versions might not
validate the required switch setting for these processors.
