3. Plug the other end of the cable into the appropriate port on the other device. Some
cables may be terminated at the other end with two separate connectors, one for each
fiber‐optic strand. In this case, ensure that the transmit fiber‐optic strand is connected
to the receive port and the receive fiber‐optic strand to the transmit port.
4. Verify that a link exists by checking that the port Link/Activity LED is on (blinking
green or solid green). If the Link/Activity LED is off, perform the following steps until
it is on:
a. Verify that the device at the other end of the segment is ON and connected to the
segment.
b. If there are separate fiber‐optic connections on the other device, check the
crossover of the cables. Swap the cable connections if necessary.
c. Check that the fiber‐optic connection meets the dB loss and cable specifications
outlined in the Cabling Guide for multimode cabling. To obtain this document,
refer to "Related Documents" on page xvi.
If a link has not been established, refer to Chapter
a problem persists, refer to "Getting Help" on page 1‐7 for details on contacting
Enterasys Networks for support.
