I installed a Cisco Aironet 3700 series AP to RB960PGS, which powered by 48V2A DC.
The AP runs in a low power mode, saying "Due to insufficient inline power. Upgrade inline power source or install power injector."
I have changed the POE option from auto to force, nothing changed.
I have upgraded the firmware of RB960PGS to latest stable 6.37.3, upgraded the firmware of AP to the latest public, changed DC power to 56V2A, nothing changed.
RB960PGS and Cisco Aironet 3700 series AP both should support 802.3at (POE+), what is wrong?
