The error codes and LED indicators are presented in the following tables.
 Descriptions used in the table
a. Error code: If an error occurs in the system, an error code is generated.
b. Description: The description of the error
c. CPU status: If the error occurs, the CPU stops running, keeps running, or shows the status you defined for the
error.
 Stop: The CPU stops running when the error occurs.
 Continue: The CPU keeps running when the error occurs.
d. LED indicator status: If the error occurs, the LED indicator is ON, OFF, or blinks.

 LED Indicator Description Table
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.
