Cause(s)
• DC-to-DC converters not
plugged in or bent pins.
• Boards not fully seated.
• Bent pin on board set or DC-to-
DC converters.
• Short on one of the boards due
to conductive item touching it.
• Boards, power pods, or
processors not fully seated.
• Wrong stepping of processor
in system for the BIOS.
• System speed set higher than
processors installed support.
• Memory not stuffed in
documented order or
unsupported/validated DIMMS
used.
• Processors or power pods not
fully seated.
• Power cable from processor
board to power pod not fully
seated.
• Power pod not fully engaged
into processor.
• Bent pin(s) on processor(s).
• Seating of processor, DC-to-DC
converters, or any board.
• Bad power pod or DC-to-DC
converter.
• Memory board or DIMM not
functional.
• Drive not fully seated.
• IDE cable or power cable not
connected to drives.
Solution(s)
• Check seating on all boards and DC-to-DC
converters.
• Check the interconnect LED on the top
cover.
• Check to make sure that you haven't
dropped a screw or other conductive item
into the system during the upgrade.
• Check the connections on all boards and
DC-to-DC converters. (Begin with those
connections that gave you the most trouble
during installation. That is typically where a
pin may have gotten bent.)
• Check for bent pins on VHDM connectors.
• Check for bent pins on processors.
• Check seating on all boards, DC-to-DC
converters, power pods and processors.
• Make sure you have the FSB to CPU core
ratio set appropriately for the processors
you're using.
• Check the BIOS release notes to ensure the
BIOS installed on the platform supports
the stepping and family of the processors
currently installed.
• Check that you have stuffed the memory
banks in the proper order. See system
documentation for proper stuffing options.
• Use only validated DIMMS at least until
you've made sure your upgrade has gone
successfully prior to testing an unknown.
• Check seating on processors and
power pods.
• Verify that you do not have any bent
processor pins.
• Check the power cable from processor
board to power pod connections.
• Check seating on all boards, DC-to-DC
converters, and processors. Check for bent
pins on all connectors.
• Replace power pod.
• Replace DC-to-DC converters.
• Check seating of memory board and
DIMMs.
• Replace DIMMs.
• Ensure proper population of DIMM banks.
• Check seating of HDD.
• Check seating of drive into adapter board.
• Check that BIOS setup has these devices
enable.
