Figure 3-4 FE-100TX Crossover Switch

Connect an FE-100TX to a Twisted Pair segment as follows:

1.Ensure that the device connected to the other end of the segment is powered ON.

2.Connect the Twisted Pair segment to the module by inserting its RJ45 connector into the RJ45 port on the module shown in Figure 3-4.

3.Verify that 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 that the device at the other end of the Twisted Pair segment is powered up.

b.Verify that the RJ45 connector on the Twisted Pair segment has the proper pinouts.

c.Check the cable for continuity.

d.Ensure that the Twisted Pair connection meets the dB loss and cable specifications outlined in Cabletron Systems Cabling Guide. Refer to Section 1.8, Related Manuals, for information on obtaining this document.

e.Confirm that the crossover switch is in the correct position.

If a link is not established, contact the Cabletron Systems Global Call Center. Refer to Section 1.7, for details.
