Diagnostics and Troubleshooting
This section consists of “Self-Test Diagnostics,” “Troubleshooting,” and “Corrective Actions.”
“Self-Test Diagnostics,” describes how to respond to errors that could be detected by the automatic
self test that is performed each time the Display Station powers up. “Troubleshooting” contains
tables of symptoms, their possible causes, and recommended corrective actions. “Corrective
Actions” contains detailed procedures that are too lengthy to include in the Troubleshooting tables.
Self-Test Diagnostics
The computer automatically performs self-test diagnostics each time it is powered up. The self-test
consists of a series of checks that verify correct performance of the computer hardware. When the
self-test is being performed, you will see the message XXXX KB OK displayed on the screen,
where XXXX is a number that increases until it matches the amount of usable memory.
System Test and Initialization
These routines test and initialize board hardware. If the routines encounter an error during the tests,
you will see an error message on the screen. There are two kinds of errors: fatal and non-fatal. If a
non-fatal error occurs, the system can usually continue the boot up sequence. Non-fatal error
messages usually appear on the screen with the following instruction:
press <F1> to RESUME
Write down the message and press the
F1
key to continue the bootup sequence.
System Configuration Verification
These routines check the current system configuration against the values stored in the CMOS
memory. If they don’t match, the program will generate an error message. To correct this condition,
you will need to run the BIOS setup program and correct the configuration information in memory.
(Refer to page 24.)
There are three situations in which you might need to change the CMOS settings:
1
.
You are starting your system for the first time.
2
.
You have changed the hardware attached to your system.
3
.
The CMOS memory had lost power and the configuration information has been erased. If this
has happened, call GE Fanuc’s CIMPLICITY hotline.
