Configuring Redundancy Options
Installing and Enabling Redundant Hardware
The standard switch configuration does not include a redundant controller
or element. The correct process is to:
■Install the redundant hardware. See “Installing Redundant
Hardware.”
■Enable the redundant hardware by using either the W eb Agent or the
CLI. See “Enabling Redundant Hardware.”
After the redundant hardware is enabled, the applicable redundant
component takes over if either a controller or any element fails.

Installing Redundant Hardware

To install redundant hardware:
1. Turn off all of the switch power supplies.
2. Replace the Primary switch contro ller 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 Figure10-1 for a P 580 or Figure 10-2 for a P882).
* Note: Controllers and elements are keyed to ensure that a contr oller is
not inserted into an element slot.
4. Install the redundant element into the redundant element slot 0 for the
P580, (see Figure 10-1), or slot 6 for the P882, (see Figure10-2).
5. Turn on the switch power supplies and log in.
6. Enable the Redundant Hardware as described in the next section.
