Can you use two injectors on an AP-225 to supply power and data to each enet port

I have several buildings where I need to install a single AP225.  None of these buildings currently have PoE switches.  Is it possible to use two injectors on a single AP225 to supply power and data to both enet ports?  Is there any benefit to running the second cat5 and injector?

If you do not have devices that can sustain more than a gigabit of wireless throughput (few if any can), there is no advantage.  There is however more cost to running a second cable and power injector to an access point.

I guess the question is why you would want to do that?  The AP only uses power from a single source at a time.

You can, it will only use one, and if one fails, the other will will take over but the AP will reboot. You will also need to LAG the ports unless you do redundant phy on the switch as a standby port.
