# Configuring Line Module Redundancy

By default, when the primary line module fails, the router automatically switches to the spare line module. Because the router is using the spare line module, no redundancy is available. The router must revert to the primary line module as soon as possible. The router does not automatically revert to the primary line module. To modify the default redundancy operations on the router, perform the following tasks:

- Disable automatic switchover on a slot.
  host1(config)#redundancy lockout 5
- Enable automatic reversion after switchover.
  host1(config)#redundancy revertive 23:00:00
