AT-MC300 Series Installation Guide

100Base-FX Fiber Optic Port

The 100Base-FX fiber optic port can use either 50/125 or 62.5/125 micron

multimode fiber cabling and can operate up to a maximum distance of 2

kilometers (1.24 miles).

100Base-TX Twisted Pair Port

The 100Base-TX twisted pair port operates with Category 5 or better twisted

pair cabling and has a maximum operating distance of 100 meters (328 feet).

The port has an RJ-45 connector.

MDI/MDI-X Switch

The MDI/MDI-X (Media Dependent Interface/Media Dependent Interface with

Crossover) switch on the front panel of the unit eliminates the need for a

crossover cable when connecting a device to the twisted pair port on the media

converter. The MDI setting is typically used when connecting a DTE device

(such as a workstation or printer) to the twisted pair port. The setting of

MDI-X is typically used when connecting a switch to the port.

System and Port LEDs

Status LEDs are located on the front panel next to each port. Table 2 lists and

defines the LEDs.
