I'm configuring a network of Aruba AP22 routers at home, and some aren't getting power from the router's supply. The POE injectors I found locally are 48V models, but Aruba recommends 57V. I've connected one to a 57V injector and it works, but I'm worried about safety or performance issues.

The AP22 needs 802.11f PoE between 44-57V and up to 10.1W. It should function properly with the 48V injectors, though you may reach the antenna output limit if you set it to maximum or overload the AP with many devices.
