Appendix A. Error Codes
Where and when are Error Codes Displayed ?
Error codes are displayed in the following locations:
1. On the LCD display, on bootup and during operation
2. On the NWS devices error lines
3. As blinking messages on the terminal screen, after the boot-up procedure is completed.
Error codes are displayed under the following circumstances:
The 3494 runs power-on diagnostics when the it is switched ON, the OS key is pressed,
•
and the UTIL key is pressed. During this time, status and error codes (if errors are
detected) are displayed on the front-panel alphanumeric display.
On successful completion of the diagnostics routine, the 3494 loads the operating
•
system software from the system diskette.
If the diagnostics routine ends routinely and the software is loaded successfully, the
•
characters [*3494*] will appear on the alphanumeric display. However, if the
process appears to end prematurely, and if a hexadecimal code is displayed (for
more than 30 seconds), an error has occurred in the process, and the system
stops.
ATTENTION!!! The displayed error code identifies the type of error. Make note of the
•
exact error code and consult the appropriate section for an explanation of the error and
suggested actions
