Online Insertion and Removal with a CIDS Network Module
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.
Unlike other network modules, CIDS network modules use hard disks. Online removal of disks without
Caution
proper shutdown can result in file system corruption and might render the disk unusable. The operating
system on the CIDS network module must be shut down in an orderly fashion before the network module
is removed.
Cisco routers support OIR with similar modules only. If you remove a network module, install another
Caution
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.
