Processors

Processors

The server requires a minimum of one Intel® Xeon™ MP processor or one Intel Xeon MP processor with iL3 cache. The processors must be installed in sequential order, from CPU socket 1 through CPU socket 4. Each processor socket must have either a processor and heat sink, or a thermal blank installed

The server automatically detects the processors each time you turn on the server. Whenever you install new processors, you should first install the most current version of the BIOS. For more information, see “Updating the BIOS” on page 155.

Special handling of Intel Xeon processors

Intel Xeon processors require special handling procedures. Make sure you follow these guidelines whenever you handle the processors:

■Follow the instructions in “Preventing static electricity discharge” on page 65.

■Ground yourself with a grounding heel or wrist strap and, if possible, an anti-static smock.

■When a processor is removed from the packaging, it should only be placed on a clean, ESD-protected work surface with its pins facing down, or installed in the server.

■When removing a processor from its packaging, keep the package flat on the surface so that the processor does not fall out.

■Hold the processor by the sides, with the pins facing down.

■Do not touch the cartridge pin array or PCB components.

■Do not stack processors on top of each other.

Installation and removal of processors

Warning

Caution

Processors and heat sinks may be hot if the computer has been running. Also, there may be sharp edges on the heat sinks. Consider wearing protective gloves.

A heat sink must be installed on the processor. Installing a processor without a heat sink could damage the processor.

Thermal blanks must be present in all processor sockets where no processor is installed. If a processor is removed, a thermal blank must be installed in the empty socket.
