Chapter 31 Connecting Cisco Wireless LAN Controller Modules Online Insertion and Removal with a Cisco Wireless LAN Controller Module Online Insertion and Removal with a Cisco Wireless LAN Controller Module The Cisco integrated services routers (ISRs) 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 OIR of the controller module is supported only on the Cisco 3745 router and the Cisco 3845 ISR. Tip For information about module slot locations and numbering on Cisco routers, see "Network Module Slot Locations and Numbering on Cisco Access Routers" section on page 1-3. For a description of informational and error messages that may appear on the console during this procedure, see the hardware installation guide for your type of router.
