PC Test Card LED: The green LED on the PC test
card (P/N35G4703) lights when the PCMCIA test is
running. If the LED does not go on, check that the card is
installed correctly by reseating the card. If it still does not
light after reseating, try using another slot for the test. If
the LED still does not go on and the test fails, replace the
FRU shown in the diagnostic error code.
Errors during the POST: If the POST detects an
error, a 3-to-8-digit error code is displayed.
Memory Errors: If the POST detects a memory error
in the first 640 KB of system memory, all the first bank
memory is deallocated and the test continues with the
second 640 KB of memory. If the total amount of
error-free memory becomes less than 2 MB, a 2XX POST
error occurs and the system stops. All the remaining
memory is used as system memory. When the POST
memory test completes, the usable memory size is
compared with the configuration data. If a mismatch is
detected, a 2XX error code occurs. The user can continue
with system operation by pressing Esc and F1 after restart
and call for service at a later time.
The memory that is deallocated because of the POST
process is kept by the hibernation or suspend functions.
For this memory to be tested, it must be reconfigured as
part of the original memory size. You configure by turning
the power off and on.
Deallocation support is done only by the POST for memory
errors. All irrecoverable memory errors that occur during
normal operation cause an interrupt to the operating
system.
Diagnostics for the SelectaDock
Docking System
The SelectaDock Docking System Options Diskette helps
you troubleshoot the expansion unit, SCSI adapter, and
SCSI device problems through a series of menus.
Run the diagnostics after you have completed the
installation of your SelectaDock Docking System and SCSI
devices to verify that these devices work correctly. Do the
following:
1. Turn off the computer on the SelectaDock Docking
System and external SCSI devices.
2. Insert the Option Diskette (the diskette is shipped with
the SelectaDock III) into drive A.
3. Turn on all attached external SCSI devices and the
computer on the SelectaDock Docking System.
4. The Logo Screen appears.
5. After a few seconds the Main Menu appears.
