Module Type LED indicator
CPU
There are five types of error indicator states for of the CPU module errors,
including LED indicator ON, OFF, blinking fast, blinking normally, and blinking
slowly. When the LED indicator is ON, blinking fast/normally, clear the problems
first in order to run the CPU module. When the LED indicator is blinking slowly,
indicating a warning type of error codes, it does not require immediate action.
Clear the problems when the module is powered off.
Error type:
ON: A serious error occurs in the module.
Blinking fast (every 0.2 seconds): unstable power supply or hardware
Failure.
Error LED
Blinking normally (every 0.5 second): system program errors or system
cannot run.
Warning type:
Blinking slowly (every 1 second and off for 3 seconds): a warning is
triggered, but the system can still run.
OFF:
A warning is triggered, but the system can still run. You can modify the rules
and use ISPSoft or SM/SR to show the warnings, instead of using indicators to
show the errors.
