On the headend and modules, there are LED's indicating the status of the system. Alle these LED's combined, gives you a overview of the system state.


This we call 'System Monitoring'. This article will describe the meaning of the LED's, in 3 parts:

  1. System LED's
  2. Input Module LED's
  3. Output Module LED's


The article will not describe, how to fix any errors. Please see the related articles or contact support for further help.


System LED's

Four LED's are placed at the top of the output section of each headend unit, and provide information on the state of the headend and sub-units (if present).


The four LED's are named (from left to right):



The LEDs can be constant green / flashing green / constant red / off. The message being indicated are different for each LED.


The meaning of the LED's can be interpreted by the following schemes.
