The Transition Networks Ethernet™ Redundant Fiber Transceiver (E-FL/RED-MC01, E-
FL/RED-MC01(SMA)) connects Ethernet IEEE 802.3 AUI (DB-15) to a redundant fiber optic
medium using standard ST type connectors (SMA available).

The Ethernet™ Redundant Fiber Transceiver operates in the following manner:

1.

Unit is powered ON with Port 1 active.

2.

Port 1 remains active as long as Link 1 is good AND data is NOT driven into
Port 2.

3.

If Link 1 fails OR if data is driven into Port 2, the redundant feature switches to
Port 2 active.

4.

Port 2 remains active as long as Link 2 is good AND data is NOT driven into
Port 1.

5.

The redundant feature switches to Port 1 active when Link 1 is good AND Port
1 is active OR when Link 2 is not good.

This equipment has been tested and found to comply with the limits for a class A digital device, pursuant to part
15 of the FCC rules.  These limits are designed to provide reasonable protection against harmful interference
when the equipment is operated in a commercial environment.  This equipment generates, uses, and can radiate
radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications.  Operation of this equipment in a residential area is likely to
cause harmful interference, in which case the user will be required to correct the interference at the user’s own
expense.

This digital apparatus does not exceed the Class A limits for radio noise for digital apparatus set out on the radio
interference regulations of the Canadian Department of Communications.

Warning
This is a Class A product. In a domestic environment this product may cause radio interference in which case
the user may be required to take adequate measures.

When power is applied through the AUI, status LEDs provide the following information:

Illuminated green LED indicates established link. (Both can be
illuminated.)

Enable(1 or 2): Illuminated green LED indicates link on which packets are being

transmitted and received.

Illuminated red LED indicates neither link is functional.
