When connecting networking devices, such as another bridge, repeater, or
router, use a straight-through cable and set the Fast Ethernet Interface
Module crossover switch shown in
Figure 3-10
to the not crossed over
position, marked with =.
A schematic of a crossover cable is shown in
Figure 3-7
. If the wires do
not cross over, use the switch on the FE-100TX to internally cross over
the RJ45 port.
Figure 3-10
shows how to properly set the FE-100TX
crossover switch.
Figure 3-10
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 the RJ45
connector on the twisted pair segment into the RJ45 port on the
module shown in
Figure 3-10
.
3.
Verify that a Link exists by checking that the port RX LED is ON
(flashing yellow, blinking green, or solid green). If the RX LED is
OFF and the TX LED is not blinking yellow, perform the following
steps until it is on:
a.
Verify 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.
d.
Make sure that the twisted pair connection meets the cable
specifications outlined in
Section 2.3
