When a Cable Problem Occurs...
If a cable problem occurs on a specified pair of wires, the Status field will show Short and then length
shown will be the approximate distance to the fault or short.
Example: Part1-2 Status = Short / Length = 2m
Explanation: A fault or short might occur at about 2m on Part 1-2.
Note: Part 4-5 and Part 7-8 are not used in a 10/100 Mbps environment, so their Status fields will show
Open, and the length shown is the approximate length of the attached LAN cable.
