Question: Can I power this device with Netonix.

Answer: Our switches are "passive" POE which means if POE is enabled on a port the power is live so if you plug in a cable that is shorted or the piece of equipment is bad or has an incompatible polarity PIN OUT you will damage the port in the switch and probably the equipment, this damage is not covered under warranty.

There are 4 Pairs and 8 PINs in an Ethernet Cable:
Pair 1: White Orange.(PIN 1 ) & Orange.(PIN 2) is POSITIVE
Pair 2: White Green...(PIN 3) & Green...(PIN 6) is NEGATIVE
Pair 3: White Blue.....(PIN 4) & Blue.....(PIN 5) is POSITIVE
Pair 4: White Brown..(PIN 7) & Brown...(PIN 8) is NEGATIVE

24V POE Option @ .75A:
Pair 3 / PINs 4, 5 are POSITIVE
Pair 2 & 4 / PINs 3, 6, 7, 8 are NEGATIVE

48V POE Option @.75A:
Pair 3 / PINs 4, 5 are POSITIVE
Pair 2 & 4 / PINs 3, 6, 7, 8 are NEGATIVE

24VH POE Option @1.5A:
Pair 1 & 3 / PINs 1, 2, 4, 5 are POSITIVE
Pair 2 & 4 / PINs 3, 6, 7, 8 are NEGATIVE

48VH POE Option @1.5A:
Pair 1 & 3 / PINs 1, 2, 4, 5 are POSITIVE
Pair 2 & 4 / PINs 3, 6, 7, 8 are NEGATIVE

So now that you know what the PIN OUT is (which is in our Spec Sheet as well on page 17 and in the product description on our web store) all you need to do is look at the spec sheet from you device and see which POE option you can use.

If they do not specify the PIN OUT polarity break out a multi-meter and cut one end off of a patch cable and strip the wires and figure it out on your own.

Also if they have a bridge rectifier circuit like MIMOSA the device will swap the polarity the way it wants it.

WARNING - If your equipment is not specifically designed to accept power on all 4 Pairs do NOT use a VH POE option.
