• Mode

There’re three

Full – tes

cable test mode for selection:

t full pairs.

Anomaly – test with only anomaly pairs.

Anomaly w/o X-pair - test anomaly pairs but without X-pair.

The Cable status includes the following items:

Object Description

• Pair

The twist pair of the UTP cable. The pair groups as follow:

(Pin 4,5)

D (Pin 7,8)

A (Pin 1,2)

B (Pin 3,

• Length[m]

When properly terminated, Cable Diagnostics reports the approximate cable length

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 a 100

Ω 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.

Be sure to running the C e 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 link down after the

cable diagnostics.
