12.2.3 BUS FAULT LED Indicator's Being ON

When a CPU module detects an error, the BUS FAULT LED indicator on the CPU module is ON. The BUS
FAULT LED indicator on the CPU module corresponds to the ERROR LED indicator on an I/O module. If an
error occurs in an I/O module, the status of the BUS FAULT LED indicator on the CPU module is the same as
that of the ERROR LED indicator on the I/O module. If there are errors occurring in the I/O modules, the BUS
FAULT LED indicator on the CPU module will be ON. For example, the BUS FAULT LED indicator on the CPU
module will be ON if the ERROR LED indicator on I/O module A is ON and the ERROR LED indicator on I/O
module B blinks. If the ERROR LED indicator on I/O module B still blinks after the error occurring in I/O module
A is eliminated, the BUS FAULT LED indicator on the CPU module will blink. Please refer to sections 12.4 in
this manual for more information about the LED indicators.
Users can get the remedies for the errors detected by a CPU module from the table below. If the error code
which users get is not listed in the table below, users need to check whether the I/O module operates normally.
Please refer to section 12.3 in this manual for more information about the troubleshooting for I/O modules.
Error
Description
code
The I/O module can not run/stop.

Remedy
Check whether the setting of the parameter for the
module is correct. If the setting is correct, please check
whether the module breaks down. If the error still occurs,
please contact the local authorized distributors.
The contents of the system backup file are incorrect, or
the file does not exist in the path specified. If the file
exists and the procedure of restoring the system can not
be executed, please backing up the system again. If the
error still occurs, please contact the local authorized
distributors. (Please refer to section 7.5 in AH500
Operation Manual, and section 18.2 in ISPSoft User
Manual for more information about the memory card.)
Check and eliminate the problem. If the problem persists,
contact the local authorized
distributors.
Check and eliminate the problem. If the problem persists,
contact the local authorized
distributors.
Check whether the module table in HWCONFIG is
consistent with the actual arrangement of the I/O
modules.
Check whether the module operates normally. If the error
still occurs, please contact the local authorized
distributors.
Set the parameter in HWCONFIG again, and download it.
Check and eliminate the problem. If the problem persists,
contact the local authorized distributors.
1. Check whether the extension backplane is connected
properly and make sure the settings on the HWCOFIG
is the same as the actual placement.
2. Check whether the extension backplane operates
normally, and make sure that the extension backplane
is not affected by noise.
