Connecting Cisco Network Admission Control Network Modules to the Network
Establishing a Gigabit Ethernet Internal Logical Connection
Use the Cisco High-Speed Intrachassis Module Interconnect (HIMI) feature to establish a Gigabit
Ethernet (GE) internal logical connection between two NMEs, or between an onboard small-form-factor
pluggable (SFP) GE module and an NME on Cisco 3825 and Cisco 3845 routers.
Ethernet (GE) internal logical connection between two NMEs, or between an onboard small-form-factor
pluggable (SFP) GE module and an NME on Cisco 3825 and Cisco 3845 routers.
Connections can be established only as follows:
•
Between the GE port in an installed onboard SFP module on the Cisco 3825 and Cisco 3845 routers
•
Between GE interfaces in NME slots 1 and 2 on the Cisco 3825 router
•
Between GE interfaces in NME slots 2 and 4 on the Cisco 3845 router
Note
A module interconnection between the GE port on an SFP module and an NME slot or an NME-to-NME
cross-connection is permitted at any given time, but both types of connections cannot exist at the same
time.

Note
Connections between the onboard RJ-45 GE ports and NME slots are not supported.

Online Insertion and Removal of Cisco NAC Network Modules
Some Cisco 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).
Module OIR provides uninterrupted operation to network users, maintains routing information, and
ensures session preservation.

Caution
Unlike other network modules, the Cisco NAC network module uses a hard disk. 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 module must be shut down in an orderly fashion before the module is
removed or powered down.

Caution
Cisco routers support OIR with similar modules only. If you remove a module, install another module
exactly like it in its place. If you remove a 2-slot module (along with any installed WAN or voice
interface cards), install another module and card combination exactly like it.
