Problem determination tips

Because of the variety of hardware and software combinations that can you can
encounter, use the following information to assist you in problem determination. If
possible, have this information available when requesting assistance from Service
Support and Engineering functions.

v Each adapter
v Drives
v Memory modules (minimum requirement = 256 MB (two banks of 128 MB
DIMMs))
The following minimum configuration is required for the computer to operate:
a. One power supply
b. System board
c. One microprocessor and VRM
d. Memory module (with a minimum of two 128 MB DIMMs)
following order:
v Power supply
v System board
replacing that adapter does not correct the problem, suspect the system board.
tests, suspect a network cabling problem external to the computer.
– Do diagnostics fail?
– What, when, where? Single or multiple computers?
– Is the failure repeatable?
– Has this configuration ever worked?
– If it has been working, what changes were made before it failed?
– Is this the original reported failure?
– Print (print screen) configuration currently in use
– BIOS code level
v Are exactly the same machine type and models
v Have the same BIOS code level
