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.
Always use the recommended minimum configuration above before removing any processors. If you are
unable to isolate the issue with the configuration above, you will then remove all but one of the processors.
CAUTION: Before removing or replacing any processors, be sure to follow the guidelines
provided in "Performing processor procedures in the troubleshooting process (on page 89 )."
Failure to follow the recommended guidelines can cause damage to the system board, requiring
replacement of the system board.
Loose connections
Action:
• Be sure all power cords are securely connected.
• Be sure all cables are properly aligned and securely connected for all external and internal
components.
• Remove and check all data and power cables for damage. Be sure no cables have bent pins or
damaged connectors.
• If a fixed cable tray is available for the server, be sure the cords and cables connected to the server are
routed correctly through the tray.
• Be sure each device is properly seated. Avoid bending or flexing circuit boards when reseating
components.
• If a device has latches, be sure they are completely closed and locked.
• Check any interlock or interconnect LEDs that may indicate a component is not connected properly.
