Hot-Swapping the Interface Module
Before hot-swapping the interface module, read the Activating or Deactivating Interface Module section
in the Cisco ASR 920 Series Aggregation Services Router Configuration Guide.
Note
The Cisco ASR-920-24SZ-IM Router provides a feature that allows you to remove and replace an interface
module without powering down the router. This feature, called hot-swapping or Online Insertion and Removal
(OIR), allows you to remove and replace an interface module without disrupting router operation.
