PM861A Redundancy Testing procedure
We are facing one issue with PM861A Controller.While doing
CPU redundancy test, change over is happening
successfully, after change over controller is going to fault
We are supplying two controller PM866 & PM861 to customer.
Redundancy Testing Procedure:
1. Check both Controllers are on ,OK & DUAL LED is ON.
2. Switchoff primary controller
3. Secondary controller will become primary
4. SwitchOn Primary controller- wait for DUAL LED on
PM866 controller is working fine for the above procedure.
But if we follow the same procedure for PM861A, we are
getting CPU error primary after powerON(@ step 4).
Is there any difference of Redundancy between PM861 &
