6. Select the check boxes that are associated with the physical ports for which you want to test
the cables.
7. Click the Apply button.
A cable test is performed on all selected ports. The cable test might take up to two
seconds to complete. If the port forms an active link with a device, the cable status is
always Normal. The test returns a cable length estimate if this feature is supported by the
PHY for the current link speed. Note that if the link is down and a cable is attached to a
10/100 Ethernet adapter, the cable status might be Open Cable or Short Cable because
some Ethernet adapters leave unused wire pairs unterminated or grounded.
The following table describes the nonconfigurable information displayed on the page.
Table 68. Cable Test information

(no link). Open Cable status at close to 0 meters (0M) may indicate that
no cable is inserted in the port.
• Short Cable. An electrical short exists in the cable.

cable might in fact be working.
