3550 Slot IDs
The following table describes the slot information displayed
on the screen. This information is also displayed during the test of the
3550 Expansion Unit when the test is successfully completed. "n" can be
any number greater than 2.

Serial and Parallel
Port Testing
Because the serial and parallel ports on the computer
are covered by the 3550 Expansion Unit when the computer is installed on
the 3550 Expansion Unit, answer "No" when you are asked if a wrap plug
is used.
Status
Indicator Testing
Test the status indicators on the 3550 Expansion Unit
by using the system status indicator test of the computer. The corresponding
indicators on the 3550 Expansion Unit turn on and off in the test, except
for the power-on indicator. This power-on indicator does not turn off due
to hardware restriction.
SCSI devices fail
or stop diagnostics
If the following SCSI devices fail
or stop diagnostics, suspect that the diagnostic programs are down level
before replacing SCSI devices.
- SCSI Tape Drive (error
code = 0211XXXX)
- SCSI CD-ROM Drive (error
code = 0215XXXX)
- SCSI Rewritable Optical
Drive (error code = 0217XXXX)
To continue the diagnostics of other devices,
remove these SCSI devices from the installed device list before starting
diagnostics.
Numeric Error Codes
Important:
1. Before replacing any SCSI devices, verify
that there are no duplicate SCSI ID settings.
2. If you have both an error message and an incorrect
audio response, diagnose the error message first.
3. If you can't run the adv. diags, but received
a POST error, diagnose the POST error
4. If you didn't receive an error message, look
for a description error symptoms in the first part of this index.
5. Check all power supply voltages before you
replace the system board of the 3550 Expansion Unit. (See "Power Systems
Checkout" )
6. If an error message is not listed, there is
a device installed that requires an additional diskette or service manual.
Refer to the diskette or the service manual for that device.

New Cover Kit
If the docking station serial number is below 97-C0001,
and the computer has intermittent problems that seem to go away when the
computer is reseated in the docking station, install the cover kit (part
number 66G9433).
Note: To check if the cover
kit has already been installed, look at the plug toward the left side of
the docking station (this plug connects to the AC adapter port at the left-rear
of the computer). If the plug has a one-eighth inch deep shoulder, the
cover kit has already been
installed. If the plug has a one-quarter inch deep shoulder, the cover
kit has not yet been installed.
