Overall Procedure
1. Check that the computer is correctly docked
to Dock II.
2. If possible, make sure that there are no hardware
setting conflicts, such as in interrupt levels, memory
addresses, DMA channels, and I/O addresses.
3. Check that the SCSI ID is set correctly.
4. Test and correct any computer problem before you
test it with Dock II. Use the computer documentation
to resolve any computer problems.
5. Test the computer with the external keyboard,
external display, mouse, and parallel and serial
device connectors. (Use the keyboard/mouse
connector to test the external keyboard and mouse.)
If no problems are found, connect the external
keyboard, mouse, parallel and serial devices to Dock
II, then connect Dock II to the computer and test it.
6. If external devices are attached to Dock II, such as an
audio amplifier, check the device by referring to the
manual shipped with the device.
7. If the user did not bring the computer with
Dock II when service is needed, use a computer that
works correctly with Dock II.
How to Diagnose Combined FRUs: If an
adapter or device consists of more than one FRU, an error
code can be caused by any of the FRUs. Before replacing
the adapter or device, remove the FRUs, one by one, to
see if the symptom changes.
