The Cisco Asynchronous Serial NIM 16-port has 3 LEDs and 24-port has 4 LEDs to display module and port statuses.

The LEDs for each port are located on the front panel and are described in the table below.

For Cisco Asynchronous Serial NIM - 16/24 Port, a new cable CAB-ASYNC-8 is introduced. The 16-port NIM has two sockets. Both the new and old cables can be plugged-in into both the sockets. The 24-port NIM has three sockets. New cables can be plugged-in into all the sockets. Old cables only can be plugged-in into sockets 1 and 3. The following table lists the cable supported:

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 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.

Electrostatic discharge can damage equipment and electrical circuitry. Electrostatic discharge occurs when electronic printed circuit cards, such as those used in Installing the Cisco Multiprotocol Synchronus Serial NIM, 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.

The following maintenance guidelines apply to the Cisco Asynchronous Serial NIM-16/24 port and SM-X-64 port for Cisco 4000 Series ISRs:

• 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.

The following safety warning statements apply to all hardware procedures involving the Cisco Asynchronous Serial NIM-16/24-port and SM-X-64-port 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 Asynchronous Serial NIM-16/24-port and SM-X-port for Cisco 4000 Series ISRs orders, and is also available on Cisco.com.

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

You must have privileged EXEC access to the router's command line interface (CLI). For more information on using the command line and for understanding command modes, see Using Cisco IOS Software.

For instructions on connecting a console to your router, refer to the documentation that accompanied your router, or refer to the online documentation for your equipment.

Perform the following steps to configure. In the below mentioned configuration steps a basic terminal server function is configured using default parameters.
