Cisco Cisco 1900 2900 3900 Series 4-Port Gigabit Ethernet HS-WIC with PoE Guía De Instalación
Installing the Cisco 1-, 2-, and 4-Port Serial Network Interface Modules for Cisco 4400 Series ISRs
Installing the Cisco 1-, 2-, and 4-port Serial NIMs in the Cisco 4400 Series ISRs

Installing the Cisco Multiprotocol Synchronus Serial NIM
Step 7
Connect the module to the network and re-enable the power to the slot in the router.
Warning
To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,
connect the Cisco 1-, 2-, and 4-Port Serial Network Interface Modules for Cisco 4400 Series ISRs only
to intra-building or unexposed wiring or cable. 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. The intrabuilding cable must be shielded and the shield must be grounded at both ends.

Step 1
Shut down the electrical power to the slot in the router either by turning off the electrical power to the
router or by issuing the online insertion and removal (OIR) commands. Leave the power cable plugged
in to channel ESD voltages to ground. For more information on OIR, see the “Managing Cisco Enhanced
Services and Network Interface Modules” chapter in the Software Configuration Guide for the Cisco
4451-X Integrated Services Router.

Step 2
Remove all network cables from the rear panel of the router.
Step 3
Using a number 1 Phillips or flat-blade screwdriver, loosen the captive screws on the NIM.
Step 4
Slide the network interface module out.
Step 5
If you are not replacing the module, install a blank faceplate over the empty slot to ensure proper air flow.
