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. Caution Unlike other network modules, network analysis modules use hard disks. Online removal of disks without proper shutdown can result in file system corruption and might render the disk unusable. The operating system on the network analysis module must be shut down in an orderly fashion before the network module is removed. 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 two-slot network module (along with any installed WAN or voice interface cards), install another module and card combination exactly like it. 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. To perform online removal of a network analysis module and insertion of a replacement, follow these steps with the router in privileged EXEC mode: Step 1 Step 2 Perform a graceful halt of the network analysis module by using the following command: Router# service-module analysis-module slot/0 shutdown Shutdown is used for Online removal of Service Module.
