Online Insertion and Removal with a Cisco PRI Network Module (Cisco 3660 and Cisco 3745 Only)

Some Cisco modular access routers allow you to replace network modules without switching off the router or affecting the operation of other interfaces. This feature is called online insertion and removal (OIR). OIR of network modules provides uninterrupted operation to network users, maintains routing information, and ensures session preservation.

Note To determine if your router supports OIR, see the hardware installation guide for your router.

Caution Cisco routers support OIR with similar modules only. If you remove a network module, install another module exactly like it in its place. If you remove a network module with an installed interface card, expansion module, or AIM, the replacement module should have the same hardware installed.

For a description of informational and error messages that may appear on the console during this procedure, refer to the hardware installation guide for your type of router.
