3. Verify a link exists by checking that the port RX LED is on (flashing amber, blinking
green, or solid green). If the RX LED is off, perform the following steps until it is on:
a. Verify the device at the other end of the segment is ON and linked 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 fiber‐optic cabling. To obtain this
document, refer to
“Related Documents” on page xvi.
If a link has not been established, refer to Chapter 4 for LED troubleshooting details. If
a problem persists, refer to “Getting Help” on page xviii for support.
4. Repeat steps 1 through 3, above, until all connections have been made.
5. 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.
