Recommended Practices for Cisco Fourth-Generation T1/E1 Voice and WAN Network Interface Module

This section describes recommended practices for safe and effective installation of the hardware described in this document.

• Safety Recommendations
• Preventing Electrostatic Discharge Damage
• General Maintenance Guidelines
• Safety Warnings

Safety warnings included in this section apply to the Cisco Fourth-Generation T1/E1 Voice and WAN Network Interface Modules that are used on Cisco 4451-X Integrated Services Router.

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 fall 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 possible hazards from your work area, such as damp floors, ungrounded power extension cables, or missing safety grounds.
• If an electrical accident occurs, proceed as follows:

– Use caution; do not become a victim yourself.

– Turn off power to the room using the emergency power-off switch.

– Determine the condition of the viction 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.

Preventing 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 and network modules, are improperly handled and can result in complete or intermittent equipment failure. Always observe the following electrostatic discharge damage (ESD) prevention procedures 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.

---

Caution 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 the metal part of the router chassis.

General Maintenance Guidelines

The following maintenance guidelines apply to the Cisco Fourth-Generation T1/E1 Voice and WAN Network Interface Module:

• 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.

Installing a Cisco Fourth-Generation T1/E1 Voice and WAN Network Interface Module in the Cisco 4451-X Integrated Services Router

---

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, including telephone cables, from the rear panel of the router.

Step 3 Remove the blank faceplates installed over the network interface module slot that you intend to use.

---

Tip Save blank faceplates for future use.

---

Step 4 Align the module with the guides in the chassis walls or slot divider and slide it gently into the NIM slot on the router.

 

Step 5 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.

Step 6 Using a number 1 Phillips or flat-blade screwdriver, tighten the captive screws on the network interface module.

Step 7 Connect the module to the network and re-enable the power to the slot in the router.
