Before I fry something....

[cwachs]

I am hooking up a Ubiquiti CRM Point to my Netonix. The CRM Point states it is "802.3af compliant" but only uses 5 volts (can be powered by USB as well).

Before I destroy this device (or burn a port on my switch), can I assume something that is 802.3af compliant is 48v on the Netonix??

Well any "passive" POE switch is not 802.3af/at compliant. What we say is we use the same pin out for polarity as 802.3af/at so you can power any 802.3af device with 48V POE option and most 802.3at devices still only use 2 pair for power so you would also use 48V. HOWEVER 802.3at has an option to use all 4 pair and "if" the device is designed to receive power on all 4 pair then you can power it with 48VH BUT MAKE SURE THE DEVICE IS DESIGNED TO RECEIVE POWER ON ALL 4 PAIR BEFORE YOU SELECT 48VH OR YOU WILL FRY IT.

If the CRM Point says it is 802.3af compliant then it would accept 48V power on 2 pair. If you read their PDF you should be fine plugging it onto our switch and powering it with 48V. I would NOT use 48VH, not sure what it would do to the device and then the port but there is no need for the device to need that much amperage anyway so 48V for the win.

UniFi Cloud Key is a close cousin and works.
