How to Remove a Controller to Simulate Controller Failure
NOTE: In Redundant Controller mode, a controller can be removed
to simulate failed controller. The other controller will take over the
IO jobs of the failed controller.
1. Loosen the two thumbscrews on Controller1 (lower Controller in the picture
below).
NOTE: If you loosened the thumbscrews and then tightened again
without removing the controller, the controller will stay in its
“failed” state. The controller needs to be removed and reinserted
in order to be back in its normal operational mode.
2. When the thumbscrews are loosened, the FLT LED will be blinking red
indicating controller failure. The IO jobs will be transferred to the other
controller (fail-over).
