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.

NOTE: If you suspect a software mismatch is causing failures (solid or intermittent), be sure to see 'Configuration Conflicts'

Check the power supplies LEDs to ensure the power supplies are operating correctly, see 'Power Supply Checkout (LED Status Descriptions)'. If the LEDs indicate the power supplies are working correctly, return here and do the following:

1.  Power-off the computer.
2.  Remove or disconnect the following (one at a time) until you find the  failure (power-on the computer and reconfigure each time).
   •  Any external devices
   •  Surge suppressor device (on the computer)
   •  Modem, printer, mouse, or non-IBM devices
   •  Each adapter
   •  Drives
   •  Memory-Module Kits

   NOTE:  Minimum operating requirements vary for each computer. For example, an IML  drive in the drive startup sequence (IML systems only).

3.  Power-on the computer. If the problem remains, suspect the system board,  then the processor board in that order.

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)
