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:

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

  1.  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).
  2.  If you suspect a networking problem and all the system tests pass,  suspect a network cabling problem external to the system.
