Installing the Multiservice Interchange Card in Cisco 3660 Routers

Product Numbers: MIX-3660-64, 78-5921-03, 78-3020-03

This document describes the multiservice interchange card (MIX). The MIX adds TDM connection capabilities between MIX-enabled network modules on a Cisco 3660 multiservice platform.

MIX functionality permits connection of TDM streams between separate network modules to support applications that are sensitive to time delay, such as voice and video. With MIX, different types of traffic can be combined on a single T1 or E1 connection, giving customers the flexibility to manage traffic through their routers efficiently, as either traditional TDM connections or in packet-based format. In addition, extended availability drop and insert (EADI) capabilities have been enhanced to allow MIX connections across slots to stay up through a router reload.

Use this document in conjunction with your router installation and configuration guide, the Regulatory Compliance and Safety Information document for your router, and the Cisco IOS configuration guides and command references. If you have questions or need help, see the "Obtaining Technical Assistance" section.

Warning Read the installation instructions before you connect the system to its power source.

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

Warning Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units.

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

Safety with Electricity

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.

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.

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.

Warning The ISDN connection is regarded as a source of voltage that should be inaccessible to user contact. Do not attempt to tamper with or open any public telephone operator (PTO)-provided equipment or connection hardware. Any hardwired connection (other than by a nonremovable, connect-one-time-only plug) must be made only by PTO staff or suitably trained engineers.

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

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

Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is OFF and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected.

Follow these guidelines when working on equipment powered by electricity:

•Locate the emergency power OFF switch in the room in which you are working. Then, if an electrical accident occurs, you can quickly shut the power OFF.

•Before working on the router, turn OFF the power and unplug the power cord.

•Disconnect all power before doing the following:

–Installing or removing a router chassis

–Working near power supplies

•Do not work alone if potentially hazardous conditions exist.

•Never assume that power is disconnected from a circuit. Always check.

•Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, and missing safety grounds.

• If an electrical accident occurs, proceed as follows:

–Use caution; do not become a victim yourself.

–Turn OFF power to the router.

–If possible, send another person to get medical aid. Otherwise, determine the condition of the victim and then call for help.

–Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It occurs when electronic printed circuit cards are improperly handled and can result in complete or intermittent failures. Always follow ESD prevention procedures when removing and replacing cards. Ensure that the router chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to an unpainted surface of the chassis frame to safely channel unwanted ESD voltages to ground. To properly guard against ESD damage and shocks, the wrist strap and cord must operate effectively. If no wrist strap is available, ground yourself by touching the metal part of the chassis.

Caution For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and 10 megohm (Mohm).

Tools and Equipment Needed

You will need the following tools and parts to install a multiservice interchange card on the router:

•Number 2 Phillips screwdriver

•T-15 Torx screwdriver

•ESD-preventive wrist strap

•MIX card assembly

Installing the MIX in the Internal TDM Slot

The multiservice interchange card does not require an external network connection; it attaches directly to the TDM slot on the Cisco 3660 motherboard. (See Figure 1.)

Figure 1 Location of TDM Slot on the Cisco 3660 Motherboard

The procedure for installing a multiservice interchange card consists of:

1. Removing the Motherboard Tray

2. Installing the Multiservice Interchange Card

3. Replacing the Motherboard Tray

The sections that follow describe these procedures.

Removing the Motherboard Tray

This section describes the procedure for removing the motherboard tray. You must remove the motherboard tray to access the internal components.

Warning Do not touch the power supply when the power cord is connected. Line voltages are present within the power supply even when the power switch is OFF and the power cord is connected.

Warning Before removing the motherboard tray, disconnect the telephone-network cables to avoid contact with telephone-network voltages.

To remove the motherboard tray:

Step 1 Power OFF the router.

Step 2 Disconnect all cables from the motherboard panel.

Step 3 Loosen the captive mounting screw on the front of the motherboard tray. (See part 1 of Figure 2.)

Step 4 Rotate the tray levers to their open position (out and away from the motherboard tray). (See part 2 of Figure 2.)

Step 5 Pull the tray levels to slide the motherboard tray out of the chassis. (See part 3 of Figure 2).
