If the Secondary Controller Fails
If the Secondary controller fails, no failover is required since the Secondary controller is
considered the backup. However, after recovering the failed unit, you should sync
controllers to ensure the configuration data is up to date on both controllers.
16.6.1
Recovering a Secondary Controller
To recover a Secondary controller:
1. Disconnect the failed Secondary controller from the network.
2. Replace or service the unit, and then restart it by plugging in the AC cable into an
AC power source. There is no power switch. The controller starts up as Secondary,
but is offline because it is disconnected from the network.
3. Reconnect the offline Secondary controller to the network.
Syncing a Recovered Secondary Controller
16.6.2
Syncing a Recovered Secondary Controller
Sync a recovered Secondary controller the same way as a Primary controller. See
Syncing Primary and Secondary Controllers
Example
For example, in Figure 16-9 when the Secondary controller fails, the changes to the
Primary controller are not updated on the Secondary unit.
