Figure 15: Removing an Interface Module from Cisco ASR-920-24SZ-IM Router
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.
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.
