Undetermined Problems

Use	the following procedure			when	the	diagnostic	tests	do
not identify the failing adapter					or	device.
Check	that	all cables,	wires,	and	connectors are		connected
so that they do not			cause	a short		circuit. If	any	problems
are	found,	reconnect	or replace		them.

Check the power supply for correct operation (see “Power Supply” on page 6). If the power supply is operating correctly, return here and continue with the following procedure:

1.Power-off the computer.

2.Remove or disconnect the following adapters or devices one at a time from the SelectaDock Docking System. (Do not isolate adapters or devices that are known to be good.)

a.Non-IBM devices.

b. A modem, printer, mouse, external keyboard, external display, external diskette drive, numeric keypad, or other external devices.

c.Any adapter.

Note

Removing an adapter or device may cause configuration errors. Ignore error code 174.

d.SCSI device.

e. Hard disk drive.

3.Power-on the system and check if the problem has changed.

4.If the symptom remains, repeat steps 1 through 3

until you find the failing adapter or device, or until all adapters or devices have been removed.

5.If all adapters or devices have been removed and the problem remains, replace the following the

SelectaDock Docking System FRUs one at a time.

	Note
	Note
If a replaced FRUs do not		resolve	the problem,
put the original FRU back in		the	SelectaDock
Docking System. Do not replace nondefective
FRUs.

a.Riser card

b.Main card

c. SelectaDock Docking System audio card

If the problem goes away when you remove an adapter,

but replacing the adapter does not correct the problem,

replace		the main card	of the SelectaDock Docking System.
