Environment : This article applies to Aruba AP-224 and AP-225 Access Points.
For an unrestricted functionality of AP-224 and AP-225, it is mandatory to connect them to power or to a PoE+ (802.3at) enabled switch port. But when connected to a POE (802.2af) power enabled switch port, below limitations are applied:
Eth1 and USB ports are disabled
5 GHz is limited to 2x3 instead of 3x3
2.4 GHz radio is limited to 1x3 instead of 3x3
NOTE: This mode is called Power Efficient Mode and the Power LED of the Access Point glows amber instead of green.
