PM866 Redundant fault Led blinking
we have problem with controller AC800M PM866 (backup controlller) fault LED blinking red, what thats mean? we have try change the backup controller, and update the firmware (on backup controller only) but the fault still appear (red blinking). The controller at the first time led dual is "On" but suddenly became "Off". what that mean? is it RCU link cable need to change? or primary controller need to update firmware?
