TC-NTP1 Inline PoE Tester Common Terms Power over Ethernet (PoE) System: A typical PoE system comprises a Power Sourcing Equipment (PSE) and Powered Device (PD). PSE: Devices that provide power over the Ethernet cable, such as PoE Switches and PoE Injectors. PD: Devices that receive power from PSE or Injector, such as IP cameras, IP phones, and Wireless Access Points. Passive PoE These type of injectors do not follow IEEE standard and they transmit power at all times.
- Never connect a reversed or unprotected PSE to the tester’s PD port, doing so can damage the PoE equipment and the tester. - When performing testing in “T-Mode”, limit the testing time to less than 20 minutes to avoid overheating the tester. - For long duration real-time inline testing, please select the “I-Mode”. - Network cable’s length and quality may affect the test result. Always perform the testing at the jack where you plan to connect the PD.
STEP Button: During inline testing (tester connects to both PSE and PD), by default the tester’s display shows voltage, amperage, and then wattage in sequence repeatedly. Pressing the STEP button once allows you to manually go through these readings one at a time starting from the voltage. This is useful for monitoring a desired reading in real-time. Ports PSE: Connection from PSE PD: Connection to PD TC-NTP1 Back Panel Testing Mode Selector I - Mode: For inline testing over a long period of time.
N - Mode: Select this mode to test passive/non-standard PoE. If you are not sure if the PSE you are testing is standard or non-standard PoE, select the T-Mode first and then connect the PSE to the tester’s PSE port. If the tester’s display does not show any reading, it is most likely a passive PoE PSE. Disconnect the PSE from the tester, select N-Mode and reconnect the PSE to the tester. During the testing, if you see “HI” on the tester’s display, this means the tester detects voltage of over 60V.
