Figure 5-40 Checking the reliability
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, which depends on 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.
If the indicators do not come on in this sequence, the Ethernet cable is unqualified.
