does this work on eap660hd ap?

Yes, it is compatible. That AP is 2.5Gbe, and requires PoE+ which this PoE injector supports.

Works with Unifi U6 Enterprise?

Dear Jose! Thanks for your interest in TRENDnet! As long has the device meet Poe or PoE+ standards. Hope this helps! If you have any more questions, you can always respond directly to this thread and someone will be happy to try and help answer any additional questions you may have! Have a great day! Adrian TRENDnet CS

ugh what is the power supply? it has a listing variation that says "with power supply" but absolutely no clear indication of jack or voltage

It contains an internal power supply that accepts standard USA 110-120v AC and comes with a cord with a standard 3-prong (5-15P)

Can this be installed in line from your normal router to push signal through the the existing ethernet cable to other side of the hoise to a switch?

No, this is a power injector for Power Over Ethernet devices which are powered through the ethernet cable rather than plugging them in to a power outlet. This device plugs in to wall power and puts power on to an ethernet circuit to power a PoE device. An ethernet segment can be 100 meters long. Unless you have a really big house, there should be no need to "push" the signal through a cable to the switch.

Leistung für PoE++ 90 Watt passt

Ich habe den Injektor gekauft, weil ich PoE++ mit 90 Watt benötigte. Hat problemlos funktioniert. Da habe ich schon anderen Erfahrungen gemacht. Für den Preis wirklich zu empfehlen.

Good product. Easy to install.

Worked great. I had 4 cameras that kept dropping out randomly. Discovered that the network switch wasn’t pushing enough power consistently to 4 of them. Added one to each camera and haven’t had any issues since, just plugged and play as advertised. Good build quality, definitely worth the money.

Buen suministro de poe 90w

Funciona bien y el componente que usa por++ 90w si lo reconoce como 90w. No lo he puesto a prueba para ver si los suministra sin problema. El único detalle es que es mas grande de lo que esperaba.

Survived a lightning strike (switch didn’t make it)

Rating five stars for surviving a lightning strike where an inline Unifi Ultra switch didn’t. This thing is magnetic so it can stick to a rack post, and high wattage. Very impressed.
