NETWORK/ POWER OVER ETHERNET (POE) TESTING
Power over Ethernet or PoE describes a specification which allows passing of electrical
power along with data on Ethernet cabling.
There are two standardized specifications the IEEE 802.3af, and IEEE 802.3at also
known as PoE+. The first provides a maximum of 12.95 Watts, and the second provides
a maximum of 25.5 Watts.
PoE also has two modes A and B. Mode A uses pins 1 and 2 for the positive voltage
and pins 3 and 6 for the negative voltage. Mode B uses pins 4 and 5 for the positive
voltage and pins 7 and 8 for the negative voltage.
The CableMaster 800/850 tests if either PoE or PoE+ is present. If it is detected, it
then activates and tests the voltage under minimum and maximum current load, and
displays the result. The CableMaster 800/850 will also display which PoE mode is
found.
Note: PoE voltages displayed in red indicate a possible issue with wire pair resistance.
This may be an indication that the cable wire is low quality aluminum clad and not
solid copper.
The CableMaster 800/850 also communicates and displays the Link Status up to
100Mb and Link Capability status up to 1000Mb..
