Hot-Swapping the Interface Module
Note 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.
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.
Caution The Cisco ASR-920-24SZ-IM Router does not support hot-swapping or OIR of TDM IM. To activate a
TDM IM you must reload the router. Without reloading the router, the IM or associated front panel ports
cannot be used. If reload is aborted, the ports 20 to 23 remain disabled and IM remains in Out-of-Service
(OOS) state until next reload.
