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.
