Symptom-to-FRU Index

The Symptom-to-FRU Index lists error symptoms and

possible causes. The most likely cause is listed first.

Note

Replace the FRUs one at a time in the sequence shown in the FRUs of the SelectaDock Sequence of Action column. If a replaced part did not resolve the problem, put the original part back in the SelectaDock Docking System. Do not replace nondefective parts.

Always	begin	with “General	Preparation” on			page 3. This
index also can be used			to help	you	decide		which FRUs to
have available when servicing the SelectaDock Docking
System.
Numeric	error	codes show	the errors detected in the POST
or system operationX s, . when			included	in	the	error	code,
can be	any	number.

FRU codes are used for errors detected by diagnostic tests.

If no error codes are available, use narrative symptoms.

If the symptom is not listed or you cannot correct the problem using this index, go to “Undetermined Problems”

on page 30.

If you cannot correct the problem using this index, go to “Undetermined Problems” on page 30.

Important

1.Before replacing any SCSI device, verify there are no duplicate SCSI ID settings.

2.Make sure there are no conflicts of hardware settings, such as, interrupt level, memory address, DMA channel, and I/O address.

3.If you have both an error message and an incorrect audio response, diagnose the error message first.

4.If you cannot run the advanced diagnostic tests, but did receive a POST error message, diagnose the POST error message.

5. If you		did	not	receive an	error	message, look	for
a description			of your error symptoms in the first
part	of	this	index.
6. Check all power supply voltages before you
replace		the	main	card, riser	card,	and audio	card
of the SelectaDock Docking System. (See
“Power	Supply”		on	page 6.)
