Network/Power Over Ethernet (Poe) Testing - Test Equipment Depot Cable Prowler TCB300 User Manual

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 12.95 Watts,
and the second provides a maximum of 25.5 W.
PoE also has two modes A and B. Mode A uses pins 1 and 2 for the posi-
tive 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 Cable Prowler tests to see if either PoE or PoE+ is present. If it is
detected It then activates it and tests the voltage under minimum and
maximum current load, and displays the result. The Cable Prowler will also
display which PoE mode is found.
While PoE is activated, the Cable Prowler also communicates and displays
the Link Status and Link Capability status.
▪ Power on the Cable Prowler.
▪ Connect the Cable Prowler to a switch or active network jack.
▪ Use the left or right arrow buttons to select the Network/PoE icon
and press the enter button or press the Network/PoE soft key.
▪ The Cable Prowler will automatically detect and display link capability,
connection speed, PoE class, and PoE Min/Max voltages.
▪ To perform a Network Test only, press the PoE soft key.
▪ To save the PoE data, press the Save soft key.
▪ Use the arrow buttons and the enter button to name the PoE file.
▪ Press the Save soft key to save the PoE file.
