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.

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.

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.
