 The TP-Link TL-WA701ND and other TP-Link AP devices do not support standard passive POE voltage (48V) but instead they supports an unusual 9V or 12V DC input. If you plug the AP in a standard passive POE injector at 48V this results in damaging the capacitors and ultimately shorting out the board. If this happens and you have a decent brick power supply, it limits the output current and you save the board, otherwise the board could be damaged irreversibly. The TP-Link TL-WA701ND and other TP-Link AP devices do not support standard passive POE voltage (48V) but instead they supports an unusual 9V or 12V DC input.

-You can easily circumvent this limitation by replacing the electrolytic capacitors on the board with the appropriate ones rated at least 63V. Replacing them is pretty straightforward, because the solder mask is quite self explanatory and the capacitors have the capacitance value written on the side.
