A dual-band 802.11ac AP must be powered by PoE. As a class 4 device, what power level should be received at the AP?
A dual-band 802.11ac AP must be powered by PoE. As a class 4 device, what power level should be received at the AP?
A class 4 PoE device, according to the IEEE 802.3at standard (also known as PoE+), should receive 25.5 watts of power at the device (Powered Device or PD). Although 30 watts can be delivered by the Power Sourcing Equipment (PSE), the actual power received by the device is 25.5 watts.
25.5W would be the nominal received power
Depends - It could be Class 4: 30.00 W at the PSE (12.95 W to 25.50 W at the PD)
Option B is the correct answer.
