Network Analysis Module Overview

This section provides information on the network analysis module (NM-NAM). (See Figure 1.)


Note The Network Analysis Module (NAM) is available in multiple hardware forms for some Cisco routers and Catalyst switches. This document applies only to the NAM for branch routers, also known as modular access, multiservice, or integrated services routers.


All network modules have an enable (EN) LED. This LED indicates that the module has passed its self-tests and is available to the router.

All network analysis modules display an additional power (PWR) LED, a disk (DISK) LED, and two additional LEDs for the Fast Ethernet port (see Figure 1).


Caution To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the network analysis module (NM-NAM) only to intrabuilding or nonexposed wiring or cabling. The intrabuilding cable must be shielded and the shield must be grounded at both ends.

Connecting Cisco Network Analysis Modules to the Network

To connect a network analysis module to the network, use a straight-through 2-pair Category 5 unshielded twisted-pair (UTP) cable to connect the RJ-45 port on the network analysis module to a switch, hub, repeater, server, or other network device. (See Figure 2.)


Caution To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the network analysis module (NM-NAM) only to intrabuilding or nonexposed wiring or cabling. The intrabuilding cable must be shielded and the shield must be grounded at both ends.


Note RJ-45 cables are not available from Cisco Systems. These cables are widely available and must be Category 5 cables.

Online Insertion and Removal with a Cisco Network Analysis 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.


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 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.
Do you want to proceed with shutdown? [confirm]
Use service module resent command to recover from shutdown

Step 2 Press Enter to confirm the request. Wait for the following status message (it may take a minute or two):

%SERVICEMODULE-5-SHUTDOWN2:Service module NAM-Sensor1/0 shutdown complete

Step 3 Unplug the network interface cable from the network analysis module.

Step 4 Loosen the two captive screws holding the network analysis module in the chassis slot.

Step 5 Remove the network analysis module from the slot.

Step 6 Align the replacement network analysis module with the guides in the chassis slot, and slide it gently into the slot.


Note If the router is not fully configured with network modules, make sure that blank panels fill the unoccupied chassis slots to provide proper airflow.


Step 7 Push the module into place until you feel the edge connector mate securely with the connector on the backplane.

Step 8 Reconnect the network interface cable previously removed in Step 3.

Step 9 Tighten the two captive screws on the faceplate.

Step 10 Reset the network analysis module using the reset command.

Router# service-module analysis-module slot/0 reset

Use reset only to recover from shutdown or failed state
Warning: May lose date on the hard disc!
Do you want to reset?[confirm]

Step 11 Press Enter to confirm the request. The network analysis module resets itself.

Step 12 Check that the network module LEDs are on and that the power and enable LEDs on the front panel also are on. This inspection ensures that connections are secure and that the new unit is operational.
