Testing a Cable
When using a 100Base-TX module, you can quickly check the cable’s link
integrity by plugging one end into port 1 and the other end into port 2. Make
sure the crossover (MDI/MDI-X) button is out. Check the Activity LEDs for
ports 1 and 2. If the LEDs are on, you have a functioning crossover cable.

sure the crossover (MDI/MDI-X) button is out. Check the Activity LEDs for
ports 1 and 2. If the LEDs are on, you have a functioning crossover cable.
If the LEDs are off, push the MDI/MDI-X button in. If the Activity LEDs
for ports 1 and 2 turn on, you have a functioning straight-through cable.
However, if the LEDs remain off, you probably have a bad cable.

However, if the LEDs remain off, you probably have a bad cable.
If a cable passes these tests, but the network connection is slow, verify that
wires 1, 2 and 3, 6 on the cable are twisted pairs, as shown in the following
diagrams.
