AT-CM301 and AT-CM302 Fast Ethernet

Media Converters Installation Guide

Overview

The AT-CM301 and AT-CM302 Media Converters are members of the Converteon family

of media converter products. They provide a simple and reliable way to connect Fast

Ethernet networks across distances of up to 2 kilometers (1.24 miles) using multimode

fiber optic cable. The products feature a 10/100Base-TX port and a 100Base-FX port.

The two cards support all of the same features, but they have different connectors on the

100Base-FX fiber optic ports. The features are listed here.

(* Requires the AT-CV5M02 Management Card.)

(** Requires an AT-CV5M02 Management Card in the upstream AT-CV5000 Chassis.)

Note

These line cards cannot be managed with the AT-CV5M01 Management Card.

Setting the DIP Switches

The line card has DIP switches for setting the operating mode. You can also set the

operating mode with the optional AT-CV5M02 Management Card. To use the DIP

switches, refer to the figure and table. For background information on the operating

modes, refer to the Converteon AT-S73, AT-S99, and AT-S102 Management Software

User’s Guide.

Installing the Media Converter

Note

The media converter supports hot swapping and can be installed while the chassis

is powered on.

To install the media converter:

1. Remove the slot cover from one of the slots in the Converteon chassis by loosening

the captive screw with a Phillips head screwdriver. The unit can be installed in any of

the media converter slots.

Note

Retain the slot cover and reinstall it if you ever remove the card. An open slot allows

dust to enter the unit and reduces proper airflow in the chassis.

2. Align the edges of the line card with the guides in the slot and carefully slide the card

into the chassis until it is flush with the front of the chassis. Light pressure may be

needed to seat the module on the connector on the backplane in the chassis.

3. Secure the line card in the chassis by tightening the captive-screw with a Phillips

head screwdriver.

4. Remove the dust cover from the fiber optic port.

5. Connect the fiber optic cable to the fiber optic port.

6. Connect a twisted pair cable to the RJ-45 twisted pair port on the line card.

LEDs

The RDY LED displays general status information.

The operating mode of the line card is displayed by the SML, ML and OAM LEDs.

The 100Base-FX port has two LEDs.

The 10/100Base-TX twisted pair port has four LEDs.

Note

For more information on the Link LEDs, refer to the explanation of the media

converter operating modes in the Converteon AT-S73, AT-S99, and AT-S102

Management Software User’s Guide.

ECO Friendly Button

The recessed ECO Friendly button on the front panel of the line card is used to toggle the

low power mode, which controls the LEDs. You can use the mode to turn off the LEDs to

conserve power when you are not monitoring them. To toggle the LEDs on or off, press

the recessed button with a pointed object, such as the end of a straightened paperclip.

You can also toggle the low power mode with the AT-CV5M02 Management Card. The

low power mode does not affect the network operations of the line card or control the

RDY LED.

Default Settings

The default settings for the media converters are listed here.
