14 Cable Test Setup and Results
The Cable Test is used to diagnose UTP twisted pairs cables (up to
Category 6e/Class E).
Note: The Cable Test can only be configurable once the Cable Test software
option is activated.
Cable test can be performed everywhere in the network where an
electrical 10/100/1000 Mbit/s Ethernet interface is available for testing. Only
the pairs used by the Ethernet signal will be tested. For 10 Base-T, and
100 Base-TX, pair 2 and 3 will be tested; for 1000 Base-T, all pairs will be
tested. However, if the Ethernet signal is unknown, all four pairs will be
tested.
Even if a link up is not required when testing with a far end equipment, it is
preferable to have the far end equipment powered up to maximize the
cable test results.
Supported Ethernet cable categories are: Category 3/Class C , Category 4 ,
Category 5 , Category 5e/Class D , and Category 6e/Class E .
Note:
Cable test result is reliable for cable length of 10 meters to 120 meters
(32.81 feet to 393.7 feet).
Note:
Cable test is only available when the Interface Type is set to 10/100/1000
Mbit/s Electrical (Refer to Interface type on page 281).
