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.

---

• 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 VDSL2 and ADSL2/2+ Network Interface Modules:

• 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.

Safety Warnings

The following safety warning statements apply to all hardware procedures involving the Cisco VDSL2 and ADSL2/2+ NIMs for Cisco 4000 Series ISRs. Translations of these warnings are available in the Cisco Network Modules and Interface Cards Regulatory Compliance and Safety Information document, which ships with all individual Cisco VDSL2 and ADSL2/2+ NIM orders, and is also available online.

Warning IMPORTANT SAFETY INSTRUCTIONS

This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents. Use the statement number provided at the end of each warning to locate its translation in the translated safety warnings that accompanied this device. Statement 1071

SAVE THESE INSTRUCTIONS

---

Warning Read the installation instructions before connecting the system to the power source. Statement 1004

---

Warning To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord. Statement 1023

---

Warning This unit might have more than one power supply connection. All connections must be removed to de-energize the unit. Statement 1028

---

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

---

Warning Do not use this product near water; for example, near a bath tub, wash bowl, kitchen sink or laundry tub, in a wet basement, or near a swimming pool. Statement 1035

---

Warning Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations. Statement 1036

---

Warning Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface. Statement 1037

---

Warning Avoid using a telephone (other than a cordless type) during an electrical storm. There may be a remote risk of electric shock from lightning. Statement 1038

---

Warning To report a gas leak, do not use a telephone in the vicinity of the leak. Statement 1039

---

Warning Ultimate disposal of this product should be handled according to all national laws and regulations. Statement 1040

---

Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046

The following warnings apply in Australia:

---

Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals. Statement 43

---

Warning Because invisible laser radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to laser radiation and do not stare into open apertures. Statement 125

---

Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. Statement 1001

---

Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Both LAN and WAN ports may use RJ-45 connectors. Use caution when connecting cables. Statement 1021

---

Warning Hazardous network voltages are present in WAN ports regardless of whether power to the router is OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, detach the end away from the router first. Statement 1026

---

Warning Before opening the chassis, disconnect the telephone-network cables to avoid contact with telephone-network voltages. Statement 1041

---

Warning The telecommunications lines must be disconnected 1) before unplugging the main power connector and/or 2) while the housing is open. Statement 1043

LEDs

The LEDs are located on the front panel and are described in Table 2 .

 

1. If both the L0 and L1 LEDs are blinking green or if one of them is blinking green and the other LED is solid green, it indicates that the Bonding mode is enabled. 2. If both L0 and L1 LEDs are solid green, it indicates that the Bonding mode is active. 3. The NIM-VA-B does not have an L1 LED since it only supports a single DSL line and does not support Bonding.

Installing the Cisco VDSL2 and ADSL2/2+ NIMs into the Cisco 4000 Series ISRs

Procedure

---

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 Cisco 4000 Series ISRs Software Configuration Guide.

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 the 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 NIM.

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