EMC38-12 USER’S GUIDE

2. Attach the other end of the 50-pin feeder cable to the Champ connector

on the 10Base-T compliant ethernet device.

3. Check that the link LED on the 10Base-T ethernet device and the

applicable

TPLNK

LED on the EMC38-12 are on. If the LEDs are not

on, perform each of the following steps until the LEDs are on:

a.

Check that the 10Base-T device and the EMC38-12 have power.

b. Verify the cabling between the EMC38-12 and the 10Base-T

device.

c.

Check the cable for continuity.

If a link has not been established, contact Cabletron Systems Technical
Support.

3.2

CONNECTING A FIBER OPTIC LINK SEGMENT

When connecting a fiber optic link segment the EMC38-12 keep the
following in mind:

ST connectors attach to ST ports much like BNC connectors attach

to BNC ports. Insert the connector into the port with the alignment
key on the connector inserted into the alignment slot on the port. The
connector is then turned to lock it down.

The physical communication link consists of two strands of fiber

optic cabling: the Transmit (TX) and the Receive (RX). The
Transmit strand from the applicable port on the module will be
connected to the Receive port of a fiber optic ethernet device at the
other end of the segment. For example, TX of the applicable port on
the module will go to RX of the other fiber optic device. The Receive
strand of the applicable port on the module will be connected to the
Transmit port of the fiber optic ethernet device. For example, RX of
the applicable port on the module will go to TX of the other fiber
optic device.
