What is a PoE Extender?
A PoE Extender allows you to extend both power and data over Ethernet beyond the standard 100 m (328 ft) limit. It receives PoE input from a PoE switch or injector and outputs power and data to the next device or another extender.
Can I connect a PoE Extender directly to a non-PoE switch?
No. A non-PoE switch does not provide power through Ethernet.
You must use a PoE injector between the switch and the extender to supply power if you do not have a PoE switch.
My PoE Extender is not working. What should I check first?
Please verify the following:
The upstream device (switch or injector) supports PoE or PoE+ (802.3af/at).
Non-PoE switches cannot power the extender.
The Ethernet cable is Cat5e or higher, in good condition, and under 100 m per segment.
The total chain length (from the switch to the final device) does not exceed the maximum supported distance.
The powered device (PD), such as a camera or AP, does not exceed the extender’s PoE output capacity.

The actual available power equals the uplink power minus the loss on the line and device’s own power consumption (see the power consumption in the spec sheet). A PoE switch or PoE adapter that supports standard IEEE PoE standard at 54 V is recommended as the uplink power source.
100m extension is measured from the GbE out to the client devices. The section between uplink switch and GbE In is determined by the uplink switch.
