Replacing a failed E2700 controller

If the E2700 controller has failed, you must replace it. In this case, you cannot perform a controlled shutdown.

1. Put on antistatic protection.
2. Label each cable attached to the E2700 controller, so you can reconnect the cables correctly.
3. Turn off power to the enclosure, which turns power off to both controllers.
4. Wait until all LED and seven-segment display activity on the rear of the controller has stopped.
5. Remove the cables.
6. Remove the controller, as described in the E2700 controller documentation.
7. Insert the new controller, as described in the E2700 controller documentation.
8. Replace all cables.
9. Turn the power back on to the enclosure.
