The procedure for testing a crossover cable is the same as that for testing a straight-through cable
except for the sequence in which the indicators turn on. You need to refer to the wire connections
of a crossover cable.
The Ethernet cable is qualified if the indicators turn on in the following sequence:
At the master (left) section of the tester, the indicators turn on in the sequence of 1-8-G. At the
slave (right) section of the tester, the indicators turn on in the sequence of 3-6-1-4-5-2-7-8-G.
Otherwise, the Ethernet cable is unqualified.
NOTE
If a tester is not available, you can use a multimeter to perform a simple test, as shown in
.
