Chapter 3: Connecting To The Network

To connect a fiber optic link segment to the EMC39-12, perform the 
following steps:

1. Remove the protective plastic covers from the fiber optic ports on the 

applicable port on the module and from the ends of the connectors on 
each fiber strand. 

2. Attach the fiber labeled 1 to the applicable Receive port, labeled RX, 

on the module. See Figure 3-2.

3. Attach the fiber labeled 2 to the applicable Transmit port labeled TX, 

on the module.

4. At the other end of the fiber optic cable, attach the fiber labeled 1 to 

the Transmit port of the device.

5. Attach the fiber labeled 2 to the Receive port.

6. Check that the FOLNK LED on the ECM39-12 is on. If the LED is 

not on, perform the following steps until it is:

a.

Check that the power is turned on for the device at the other end of 
the link.

b. Verify proper “receive to transmit” connection of fiber strands 

between the applicable port on the module and the fiber optic 
device at the other end of the fiber optic link segment.

c.

Verify that the fiber connection meets the dB loss specifications 
outlined in Appendix A.

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