Installing Redundant Hardware

To install redundant hardware:

1. Turn off all of the switch power supplies.
2. Replace the Primary switch controller with the new switch controller. This ensures that the switch checks the status of the new switch controller.
3. Insert the previously Primary switch controller into the Redundant Controller Slot 1 (see Figure�84 for a P580 or Figure�85 for a P882).

Note: Controllers and elements are keyed to ensure that a controller is not inserted into an element slot.

4. Install the redundant element into the redundant element slot 0 for the P580, (see Figure�84), or slot 6 for the P882, (see Figure�85).
5. Turn on the switch power supplies and log in.
6. Enable the Redundant Hardware as described in the next section.
