Unpacking and Installing Your ELS10-26
determine if the wires have been crossed over for the proper
connection.
A schematic of a crossover cable is shown in Figure 2-6. If the wires
do not cross over, use the switch on the FE-100TX to internally
cross over the RJ45 port. Figure 2-7 shows how to properly set the
FE-100TX crossover switch.
Figure 2-7. FE-100TX Crossover Switch
Connect an FE-100TX to a twisted pair segment as follows:
1. Ensure that the device at the other end of the segment is
connected to the segment and is powered ON.
2. Connect the twisted pair segment to the module by inserting
the RJ45 connector on the twisted pair segment into the RJ45
port on the module. See Figure 2-7.
3. Verify that a Link exists by checking that the port LINK LED is
on (solid green). If the LINK LED is off, perform the following
steps until it is on:
a. Check that the 100BASE-TX 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.
