AT-CM70S Converteon Line Card Installation Guide

Overview

The AT-CM70S line card is a 10/100 Mbps Ethernet copper-to-fiber media converter line

card that provides Time Division Multiplexing (TDM) (T1/E1) transport in addition to

regular Ethernet traffic and OAM link management capability. This line card offers support

for 1.544 Mbps (T1) and 2.048 Mbps (E1) services with complete synchronization for toll-

quality transport of voice, video, and data. It also accommodates traditional testing

equipment currently used on SONET/SDH equipment for testing T1/E1 services. You can

install the AT-CM70S line card in any Converteon Series chassis except the AT-CV1000.

The AT-CM70S line card is hot swappable into and out of a Converteon chassis. The line

card requires two adjacent line card slots.

AT-CM70S Line Card Components

An AT-CM70S line card has the components shown below.

Port Descriptions

SFP Port

The SFP port supports an SFP transceiver with a fixed operating speed of 100 Mbps. The

port multiplexes the T1/E1 and twisted pair ports into a single fiber interface for a

distance of up to 40 km. Another AT-CM70S line card must be installed in the remote

chassis to de-multiplex the signals.

Console Port

The console port allows you to configure the AT-CM70S line card when no AT-CV5M0x

management card is installed.

Note

By default, the console port is active. However, if you configure the AT-CM70S line

card using the management software, ensure that the operating mode is “Line Card

DIP Switch” mode to keep the console port active. You cannot configure this setting

using the DIP switches on the line card.

The default settings for the RS-232 console port are:

 Baud rate: 115200 bps (range 2400 to 115200 bps)

 Data bits: 8

 Parity: None

 Stop bits: 1

 Flow control: None

A console port cable is provided.

Twisted Pair Port

The 10/100Base-TX compliant twisted pair port has an RJ-45 connector and a maximum

operating distance of 100 meters (328 feet). Category 5 (5E), 100 Ohm shielded or

unshielded twisted pair cabling is required. The pinouts for this port are shown in

“Twisted Pair Port Pinouts.”

T1/E1 Ports

Each T1 port supports a maximum rate of 1.544 Mbps and a maximum line length of

6000 ft. over 100 Ohm balanced cable. Each E1 port supports a maximum rate of 2.048

Mbps and a maximum line length of 2.5 km over 120 Ohm balanced twisted pair cable.

LEDs

The AT-CM70S line card has three status LEDs, one LED for the SFP port, three LEDs for

the twisted pair port, and four LEDs for each T1/E1 port as described in “LED Descriptions.”

DIP Switches

One set of two DIP switches allow you to set the operating mode of the line card, as

described in “DIP Switch Settings.”

Recessed CPU Reset Button

The recessed CPU RESET button allows you to manually reset the AT-CM70S line card

when the chassis does not contain an AT-CV5M0x management card or when an

AT-CV5M0x management card is installed but you cannot reset the card through the

management software.

Installing an AT-CM70S Line Card

Note

Before you install an AT-CM70S line card, refer to the appropriate Converteon

chassis installation guide for electrical safety and emissions information.

Note

You can install this Converteon line card in any two adjacent Converteon chassis

line card slots.

To install an AT-CM70S line card, perform the following procedure:

1. Remove the AT-CM70S line card from its shipping package and store the package in

a safe place. You must use the original package if you need to return the unit to

Allied Telesis.

2. Configure the line card’s DIP switches as required. Refer to “DIP Settings” for more

information.

3. Select two adjacent line cards slot in the chassis where you want to install the

AT-CM70S line card and remove the blank slot covers if they are installed.

4. Align the back edge of the line card with the top and bottom alignment guides located

inside the slots.

5. Slide the line card into the slots until the front of the card is flush with the front of the

chassis.

Note

Avoid touching the line card components.

6. Secure the AT-CM70S line card to the chassis by using a Phillips screwdriver to

tighten the captive screw on the faceplate.

Note

Always tighten the captive screw to secure the line card to the chassis.

LED Descriptions

Status LEDs

The line card has three status LEDs as described in the following table. For more

information about OAM, refer to the relevant management software user’s guide.

SFP Port LED

The SFP port has one LED, as described in the following table.

Warning: Remove all metal jewelry, such as rings and watches, before installing

or removing a line card from a powered-on chassis.

Caution: Be sure to observe all standard electrostatic (ESD) precautions, such

as wearing an antistatic wrist strap, to avoid damaging the device. A line card can

be damaged by static electricity.

Caution: Before installing this line card in an AT-CV120x chassis, ensure that the

chassis is grounded as described in the AT-CV120x Chassis Installation Guide.

LED State Description

RDY Green The line card has passed diagnostics.

Off The line card has not passed diagnostics.

OAM Green The OAM mode is enabled (visible or bypass). You use the

DIP switches to set the OAM mode, as described in “DIP

Switch Settings.”

Off The OAM mode is disabled.

Console Green The line card is being managed through the console port.

Off The line card is being managed through a management card.

LED State Description
