Brand shouldn't make a difference. Make sure that the power output is what your requirements call for. If not, you could end up replacing devices.

So every product uses the same protocol ? do you have experience with connecting two different adapters?
Jay LewisCEOCommented:
As long as they are both POE, or POE+, and not one of each, then you should be ok.  There is a difference between to voltage of the two: The maximum amount of power for the 802.3af (PoE) standard is 15.4 watts.  The maximum for the 802.3at (PoE+) standard is 25.5 watts.

So if one was purchased long time ago, and one recently the probability they will be able to communicate is very low?
Jay LewisCEOCommented:
I would recommend that you Google the specs on each and determine if they are both POE.  It's tough to answer your question without more information.

There is no difference in Voltage, difference is Wattage.
:)
Difference is power that those can offer (So Max Amp is different, Voltage is in the same range) P = I × V. And since I (number of Amps that can be delivered) is different most likely you can mix those even if those are not of the same kind with no issues (sure, depending on how you use it).
