Shutting Down NAM Enhanced Network Modules
Press the reset button on the network module faceplate for less than 2 seconds to perform a graceful
shutdown of the network module before removing power from the router or before starting an online
insertion and removal (OIR) sequence on the router. The application may take up to 2 minutes to fully
shut down.
If you press the shutdown button for more than 4 seconds, a nongraceful shutdown of the hard disk will

occur and may cause file corruption on the network module's hard disk. After a nongraceful shutdown,
the HD and SYS LEDs remain lit. Press the shutdown button for less than 2 seconds to gracefully reboot
the network module.
Connecting NAM Enhanced Network Modules
Warning To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,
connect the NAM enhanced network module (NME-NAM-80S) only to intra-building or non-exposed
wiring or cabling. The intrabuilding cable must be shielded and the shield must be grounded at both
ends. The intra-building port(s) of the equipment or subassembly must not be metallically connected
to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as
intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 4) and
require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient
protection in order to connect these interfaces metallically to OSP wiring.
To connect NAM enhanced network modules to an external device, use a straight-through two-pair
Category 5e unshielded twisted-pair (UTP) cable, and connect the RJ-45 Gigabit Ethernet port on the
network module to a switch, hub, repeater, server, or other Gigabit Ethernet network device.
RJ-45 cables are not available from Cisco Systems, Inc. These cables are widely available and must be

Category 5e cables.
Online Insertion and Removal of Cisco NAM Enhanced Network
Modules Procedure
Some Cisco 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 a
module provides uninterrupted operation to network users, maintains routing information, and ensures
session preservation.
Unlike other network modules, NAM enhanced network modules use hard disks. Online removal of
Caution
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 way before
removing or powering down the module.
