Performing processor procedures in the troubleshooting process

Before performing any troubleshooting steps that involve processors, review the following guidelines:

Be sure that only authorized personnel perform the troubleshooting steps that involve installing,
removing, or replacing a processor.

Always locate the documentation for your processor model before performing any steps that require
installing, removing, or replacing a processor. If you cannot locate the hard copy of the instructions that

shipped with the processor, see the processor ("

Processor option

" on page

29

) instructions in this

document.

Some processor models require the use of a processor installation tool, and specific steps are
documented to ensure that you do not damage the processor or processor socket on the system board.

For server models that have pins inside the processor socket, remember that THE PINS ON THE SYSTEM
BOARD ARE VERY FRAGILE AND EASILY DAMAGED. If you damage the socket, you must replace the

system board.

Depending on the server blade model, the contacts may be on the processor or they may be inside the
processor socket. Never touch the contacts. THE PINS ON THE SYSTEM BOARD ARE VERY FRAGILE AND

EASILY DAMAGED. If the contacts inside the processor socket are damaged, the system board must be

replaced.

Always complete all other troubleshooting procedures before removing or replacing a processor.

Breaking the server down to the minimum hardware configuration

During the troubleshooting process, you may be asked to break the server down to the minimum hardware

configuration. A minimum configuration consists of only the components needed to boot the server and
successfully pass POST.
When requested to break the server down to the minimum configuration, uninstall the following components,

if installed:

All additional DIMMs
Leave only the minimum required to boot the server—either one DIMM or a pair of DIMMs. For more
information, see the memory guidelines in the server user guide.

All additional cooling fans, if applicable
For the minimum fan configuration, see the server user guide.

All additional power supplies, if applicable (leave one installed)

All hard drives

All optical drives (DVD-ROM, CD-ROM, and so forth)

All optional mezzanine cards

All expansion boards

Before removing the components, be sure to determine the minimum configuration for each component and

follow all guidelines in the server user guide.
