Installing V.110 12-Port Modules in Cisco AS5200 Universal Access Servers

Product Number: AS52-12-TA-V110

This document describes how to install and configure V.110 12-port modules in Cisco AS5200 universal access servers, and includes the following sections:

Overview

The V.110 12-port module, shown in Figure 4, includes onboard terminal adapters (TAs) that can terminate up to 12 V.110 bit rate adapted digital calls. Bit rate adaption protocols map the PC communications port speed (for example, 9600, 19200, and 38400 bps) to the faster data rate (64000 bps) of Integrated Services Digital Network (ISDN) B channels. The V.110 module supports a maximum data rate of 19200 bps on all ports simultaneously.

The V.110 rate adaption protocol is used primarily for:

Safety with Electricity

Follow these guidelines when working on equipment powered by electricity:

Read the installation instructions before you connect the system to its power source.
Ultimate disposal of this product should be handled according to all national laws and regulations.
Only trained and qualified personnel should be allowed to install or replace this equipment.
To ensure your safety and the safety of others, be sure the power is OFF and the power cord is unplugged before working on the router.
  • Disconnect all power before doing the following:
    • Installing or removing a chassis
    • Working near power supplies
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.
  • 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 system.
    • 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 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.

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

Installing the V.110 12-Port Module

You must install V.110 modules in a carrier card or a dual E1/PRI card, which are not included with this kit. The carrier card, shown in Figure 2, is a wide, narrow card with two slots in which you can install up to two V.110 modules (or other supported modules). Figure 3 shows the dual E1/PRI card, which has only one slot. You can install V.110 modules with any combination of other supported modules.


Figure 2   Carrier Card



Figure 3   Dual E1/PRI Card


Required Tools

You need the following tools:

  • ESD-preventive wrist strap
  • Medium-size flat-blade screwdriver (1/4 inch [0.625 cm])

Installation

Refer to Figure 4 and take these steps:

Step 1   Attach an ESD-preventive wrist strap.

Step 2   Power OFF the access server.

Unlike some other Cisco access servers, the modules are not hot-swappable (that is, you cannot remove or install them when the access server power is ON). Be sure to power OFF the access server before installing or removing modules. Failure to do so can damage the access server.

Step 3   Remove all interface cables from the rear panel of the access server.

Step 4   Remove the blank cover or module installed in the carrier card or dual E1/PRI card.

Note If the carrier card or dual E1/PRI card is already installed in the access server, you can install V.110 modules in the card without removing it from the chassis.

Step 5   Remove the V.110 module from the ESD-preventive shipping material.

Step 6   Slide the V.110 module into the carrier or dual E1/PRI card slot until it is seated completely.

Step 7   Tighten the two captive screws on the V.110 module to secure it to the carrier card or dual E1/PRI card.
