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 Resource Conflicts'.
  2.  A corrupt CMOS can cause undetermined problems.

Check the LEDs on all the power supplies. 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).


     Minimum operating requirements are:

     Power Supply
     Power AC Inlet Box
     System Board (Use switch 7 on the switch
     block on the system board to bypass the  power switch button. Also, verify that the  J10 connector is 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.
