The Cable Status includes the following items: Table 4-38 Description of the Cable Status.
Item Description
• Pair
The twist pair of the UTP cable. The pair groups as follow:
A (Pin 1,2)
B (Pin 3,6)
C (Pin 4,5)
D (Pin 7,8)
• Length[m]
When properly terminated, Cable Diagnostics reports the approximate cable length in meters of
each of the four cable pair A, B, C, and D.
• Status
The cable test results. Possible values are:
• Proper - The cable passed the test.
• Open - The cable is connected on only one side or there is no cable connected to the port
• Short - A short has occurred in the cable. With 10/100BASE link, the status of Pair C and Pair
D will be “Short”.
• Abnormal termination – An improper termination be detected. Proper termination of Cat5
cable requires 100Ω differential impedance between the positive and negative cable
terminals. IEEE STD 802.3 allows for a termination of as large as 115Ω or as small
as 85Ω. If the termination falls out of this range, it is reported as falls an anomalous
termination.
Table 4-38 Description of the Cable Status
Be sure to running the Cable diagnostics with standard Cat 5e or Cat 6 UTP cable. With some of the UTP
cables that not match the standard of Cat 5e, it might cause the 10/100Base-TX link down after the cable
diagnostics.
