Cisco Intrusion Detection System Appliance and Module Installation and Configuration Guide Version 4.1

We recommend that you assign a loopback address on the monitoring interface,
otherwise if the IP address is advertised through routing updates, the monitoring
interface can become vulnerable to attacks.
See
Configuring Cisco IDS Interfaces on the Router, page 10-78
for assigning the IP address to gain access to the console and for setting up a
loopback address.
You must install the NM-CIDS offline in Cisco 2650XM, 2651XM, and 2961
series routers.
To avoid damaging the NM-CIDS, you must turn OFF electrical power and
disconnect network cables before you insert the NM-CIDS into a chassis slot or
remove the NM-CIDS from a chassis slot.
Cisco 3660 and Cisco 3700 series routers allow you to replace network modules
without switching off the router or affecting the operation of other interfaces.
Online insertion and removal (OIR) provides uninterrupted operation to network
users, maintains routing information, and ensures session preservation.
Cisco 2600, 3600, and 3700 series routers support only one NM-CIDS per chassis.
Unlike other network modules, the NM-CIDS uses a hard-disk drive. Online
removal of hard-disk drives without proper shutdown can result in file system
corruption and might render the hard-disk drive unusable. The operating system
on the NM-CIDS must be shut down in an orderly fashion before it is removed.
