Cisco C-NIM-WAN-2X and C-NIM-WAN-4S Module Network Interface Module
The Cisco C-NIM-WAN-2X and C-NIM-WAN-4S are the next generation Form-factor WAN NIM modules that provide enhanced security, reliability, and performance. The Cisco C-NIM-WAN-2X module provides Small Form-Factor Pluggable Plus (SFP+), 10G and 1 Gigabit connectivity. The Cisco C-NIM-WAN-4Smodule provides 1 Gigabit SFP connectivity. The Cisco C-NIM-WAN-2X and C-NIM-WAN-4S modules are supported only in a NIM slot. These modules can only be supported in the SM-NIM Carrier Adapter in the non-NEBS setup.
This article describes how to install the C-NIM-WAN-2X and C-NIM-WAN-4S Network Interface modules. This chapter also includes the installation of Small-Form-Factor pluggable (SFP+) modules. It also describes how to connect the module in your network.

Prepare for installation
These sections describe safety warnings, general maintenance guidelines, and safety recommendations that you must read before installing and using the module:
Safety warnings
 Warning |
To reduce risk of fire, explosion, or leakage of flammable liquid or gas:
|
Warning |
Blank faceplates and cover panels serve three important functions: they reduce the risk of electric shock and fire, they contain electromagnetic interference (EMI) that might disrupt other equipment, and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. |
Warning |
Do not use this product near water, for example, near a bathtub, wash bowl, kitchen sink, laundry tub, in a wet basement, or near a swimming pool. |
Warning |
Avoid using a telephone (other than a cordless type) during an electrical storm. There may be a risk of electric shock from lightning. |
Warning |
To reduce the risk of ignition, do not use a telephone in the vicinity of a gas leak. |
Prevent electrostatic discharge damage
Electrostatic discharge can damage equipment and electrical circuitry. Electrostatic discharge occurs when electronic printed circuit cards, such as those used in Cisco service modules, are not handled properly. Improper handling can result in complete or intermittent equipment failure. Always observe the following procedures to prevent electrostatic discharge damage (ESD) when installing, removing, or replacing any electronic printed circuit cards:
-
Make sure that the router chassis is electrically connected to earth ground.
-
Wear an ESD-preventive wrist strap, and make sure that it makes good contact with your skin.
-
Connect the wrist strap clip to an unpainted portion of the chassis frame to channel unwanted ESD voltages to ground.
-
The wrist strap and clip must be used correctly to ensure proper ESD protection. Periodically confirm that the resistance value of the ESD-preventive wrist strap is between 1 and 10 megohms (Mohm).
-
If no wrist strap is available, ground yourself by touching a metal part of the router chassis.
General maintenance guidelines and safety recommendations for C-NIM-WAN-2X and C-NIM-WAN-4S Module
This section outlines the general maintenance and safety recommendations for the modules.
General maintenance guidelines
-
Keep the router chassis area clear and dust-free during and after installation.
-
If you remove the chassis cover for any reason, store it in a safe place.
-
Do not perform any action that creates a hazard to people or makes equipment unsafe.
-
Keep walk areas clear to prevent falls or damage to equipment.
-
Follow installation and maintenance procedures as documented by Cisco Systems, Inc.
-
Always wear an electrostatic discharge (ESD)-preventive wrist strap, and ensure that it makes good contact with your skin when you remove or install an Service Module (SM). Connect the equipment end of the wrist strap to a metal part of the chassis.
-
Handle the NIMs only by their edges. SMs are ESD-sensitive components and can be damaged by mishandling.
Safety recommendations
To prevent hazardous conditions, follow these safety recommendations while working with this equipment:
-
Keep tools away from walk areas where you or others could trip over them.
-
Do not wear loose clothing around the router. Fasten your tie or scarf and roll up your sleeves to prevent clothing from being caught in the chassis.
-
Wear safety glasses when working under any conditions that might be hazardous to your eyes.
-
Locate the emergency power-off switch in the room before you start working. If an electrical accident occurs, shut the power off.
-
Before working on the router, turn off the power and unplug the power cord.
-
Disconnect all power sources before doing the following:
-
Installing or removing a router chassis
-
Working near power supplies
-
-
Do not work alone if potentially hazardous conditions exist.
-
Always check that power is disconnected from a circuit.
-
Remove, from your work area, possible hazards such as damp floors, ungrounded power extension cables, or missing safety grounds.
-
If an electrical accident occurs to another person with you, proceed as follows:
-
Turn off power to the room using the emergency power-off switch.
-
Determine the condition of the victim and send another person to get medical aid or call for help.
-
Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.
