Cisco Cisco 1900 2900 3900 Series 4-Port Gigabit Ethernet HS-WIC with PoE Installation Guide

This section describes the following installation tasks for Cisco 1-, 2-, and 4-Port Serial Network 
Interface Modules for Cisco 4400 Series ISRs.

You will need the following tools and equipment while working with the Cisco 1-, 2-, and 4-Port Serial 
Network Interface Modules for Cisco 4400 Series ISRs:

Number 1 Phillips screwdriver or a small flat-blade screwdriver

ESD-preventive wrist strap

No user-serviceable parts inside. Do not open. Statement 1073

Only trained and qualified personnel should be allowed to install, replace, or service this equipment. 
Statement 1030

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 
4400 Series Integrated Services Routers.

Remove all network cables from the rear panel of the router.

Remove the blank faceplates installed over the network interface module slot that you intend to use. 

Save blank faceplates for future use.

Align the module with the guides in the chassis walls or slot divider and slide it gently into the NIM slot 
on the router. 

Push the module into place until you feel the edge connector seat securely into the connector on the 
router backplane. The module faceplate should contact the chassis rear panel.

Using a number 1 Phillips or flat-blade screwdriver, tighten the captive screws on the network interface 
module.
