Symptom-to-FRU Index
The
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.) |
