2.3 PoE & LAN

The 2 ports PoE extender doesn’t require an external PoE supply unit, but it does need power from PSE (a PoE switch or PoE injector). The remaining power depends on the PSE. If the PSE is compatible with IEEE802.3bt standard and can supply 95W high power POE, the maximum pass-through power is 60W. However, while the PSE (a PoE switch or PoE injector) is IEEE802.3at which only supplies 32W maximum, the remaining power is unable to reach 60W at the POE extender.

You also need to consider the power loss inline and the power consumption using by the PoE extender (about 3W).

The PoE extender is transparent to TCP/IP, basically, it is plug and play.

1.  Connect the PoE input port to your PSE (PoE injector/PoE switch). The PoE input indicator should light up after a while.

2.  Connect one of the PoE output ports to your PoE edge device, the LAN indicator will be light up as well.

3.  Both indicators will start flashing while there are data exchanging.

4.  Now you can start assembly the grand properly.

Working with Non-PoE device.

The PoE extender also can work with a non-PoE device. The PoE extender only will provide the data but no power to the edge devices while it is not a feature with PoE. There is a power handshake in IEEE802.3af/at/bt standard PoE. The PoE extender will release a small current to detect whether your edge IP device features with POE or not. While the PoE extender can’t receive the correct feedback, the POE extender will not release the power to the edge.
