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

 

 

 

 

 

 

 

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.
