converter products. It is a simple and reliable way to connect Fast or Gigabit Ethernet
networks across small or large geographical distances with fiber optic cable. The product
features a 10/100/1000Base-T port for a local connection and a slot for a 100Base-FX or
1000Base-X SFP module for a remote connection using multimode or single-mode fiber
optic cable. The features of the media converter are listed here.

Reviewing Safety Precautions
Before installing the media converter, review the safety precautions detailed in the
Converteon chassis’ Installation Guide.
Cable Specifications
The cable specifications for the 10/100/1000Base-T twisted pair port are listed here.
For the fiber optic cable specifications, refer to the SFP module instructions.
Setting the Operating Mode
There are DIP switches on the line card for setting the card’s 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 line 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.
