Power over Ethernet (PoE)

Both TestPro and Network Service Assistant (NSA) provide a comprehensive test function for verifying PoE deployments up to 90W. UPoE and all PoE standards are supported, which include 802.3af/at/bt. The PoE source is tested with actual load connection. TestPro and NSA offer the unique ability to test internal and external load test over a sustained time period to validate the maximum power a PoE link can support. TestPro and NSA will also check that the cable installation meets the required power to turn on a PoE devices.

In addition to operational tests on PoE, the tester enables characterization of cabling links for DC Resistance Unbalance parameters in accordance with the latest TIA 1152A standard for certification testing.  This can be done as a one-off test, or included in a cable certification with TestPro, or a Qualification+ / Certi-Lite testing with NSA.  For TestPro, the complete Autotest including all standards certification test parameters in addition to added parameters is still 6 seconds for CAT6A! 

When performing a PoE test, a remote tester is not needed as you are testing directly into the switch. In this case, you may convert your TestPro Remote into a Main under Setting/Device Type and deploy each tester individually to perform these tests.

  • PSE detection
  • Voltage: Voltage drawn by the PD
  • PSE Type: 1-2, 2, 3-4, and 4 –different types have different allocated power
  • PD Class: 0-8 –different classes have different allocated power
  • PoE Cable airs: Cable pairs used to transmit electrical power
  • Allocated Power: Power allocated for the PD
  • Real Power: Power when internal or external load is used

Internal and External Load Tests:

  • Voltage
  • Current
  • Real Power: The actual power available at the endpoint when a device draws power (load) through the PoE circuit. This can be measured using the tester’s internal load or using an external load.
