Figure 4-335 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
qualied 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
unqualied.
NO TE
If a tester is not available, you can use a multimeter to perform a simple test, as
shown in Figure 4-336.
