CHAPTER 3: CONNECTING TO THE NETWORK

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.

3.2CONNECTING 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.
