This motherboard incorporates cable diagnostic feature designed to detect the status of the attached LAN cable. This feature will detect cabling issue and report the approximate distance to the fault or short. Refer to the following information for diagnosing your LAN cable:

When LAN Cable Is Functioning Normally...

1.If no cable problem is detected on the LAN cable connected to a Gigabit hub, the Status fields of Pair 1-2, Pair 3-6, Pair 4-5, and Pair 7-8 will show Normal and the Length fields will show N/A,as shown in the figure above.

2.If no cable problem is detected on the LAN cable connected to a 10/100 Mbps hub, the Status fields of Pair 1-2 and Pair 3-6 will show Normal and the Length fields will show N/A.

However, because Pair 4-5 and Pair 7-8 are not used in a 10/100 Mbps environment, their Status fields will show Short or Open, and the length shown is the approximate length of the attached LAN cable.

When a Cable Problem Occurs...

If a cable problem occurs on a specified pair of wires, the Status field will show Short or Open and the length shown will be the approximate distance to the fault or short.

For example, if it shows Pair1-2 Status = Short / Length = 1.6m, it means that a fault or short might occur at about 1.6m on Pair 1-2.

When No LAN Cable Is Attached...

If no LAN cable is attached to the motherboard, the Status fields of all four pairs of wires will show Open.
