Undetermined problems
You are here because the diagnostic tests did not identify
the failure, the Devices List is incorrect, or the system is
inoperative.
Notes
If you suspect a software mismatch is causing failures
(solid or intermittent), be sure to see “Configuration
conflicts” on page 20.
Check power supply. 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 (Minimum requirement = 1
bank of 64 MB DIMMs)
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 following FRUs in the order listed:
System Board
Processor Board
Front Panel
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).
