Undetermined Problems

Undetermined Problems

You are here because the diagnostic tests did not identify the failure, the Devices List is incorrect, or the system is inoperative.


  1.  If you suspect a software mismatch is causing  failures (solid or intermittent), be sure to see 'Resolving Configuration Conflicts'
  2.  A corrupt CMOS can cause undetermined  problems.

Check the LEDs on all the power supplies, see 'Power Supply LED Errors'. If the LEDs indicate the power supplies are working correctly, return here and do the following:

  1.  Power-off the computer.
  2.  Be sure the system is cabled correctly.
  3.  Remove or disconnect the following (one at a time)  until you find the failure (power-on the computer and  reconfigure each time).

    Note:  Minimum operating requirements are:

     Power Supply
     Power Backplane
     Power AC Inlet Box
     System Board (With pins 2 and 3 of J32  connected together to bypass the power  switch (button). The default is pins 1 and  2.)
     Processor Board (Verify that the J10 and  J17 connectors are are installed correctly.)
     Memory-Module Kits (Minimum requirement  = 1 bank of 64 MB DIMMs)

  4.  Power-on the computer. If the problem remains,  suspect the following FRUs in the order listed:

Note: If the problem goes away when you remove an adapter from the system, and replacing that adapter does not correct the problem, suspect the system board then the processor board(s)
