1.4 EMC39-12 FEATURES
The EMC39-12 Ethernet Media Converter provides connectivity for up to twelve singlemode fiber optic connections. The network connection is made through a 50-pin connector on the rear of the unit.
The EMC39-12 supports the following:
•Automatic Transmit Port Disable
•Full Duplex Ethernet Support
•LANVIEW Diagnostic LEDs
•Connectivity
The following sections discuss these features.
1.4.1 Automatic Transmit Port Disable
The EMC39-12 automatically disables the Transmit port when its corresponding Receive port does not have a link.
1.4.2 Full Duplex Ethernet Support
All of the EMC39-12 ports support Full Duplex Ethernet provided that the device at the other end of the port supports Full Duplex Ethernet also. Full Duplex Ethernet allows the EMC39-12 to transmit and receive signals simultaneously for a 20 Megabit bandwidth through-put.
1.4.3 LANVIEW Diagnostic LEDs
Cabletron Systems equips the EMC39-12 with a visual diagnostic and monitoring system called LANVIEW. LANVIEW LEDs help you quickly identify Power and Link status. Chapter 4 describes the LEDs in detail.
1.4.4 Connectivity
The rear panel of the EMC39-12 has a 50-pin Champ connector (RJ71) that supports twelve twisted pair segments. The front panel has twelve 10BASE-FL single mode ST ports. Each single mode ST port has a Receive connector and a Transmit connector.
