Which issue may be causing the new door locks on the APs to not work?
The correct answer is C. AF power to the AP is not enough. 802.3af (AF) PoE provides the least power. Many new devices, such as door locks attached to APs, require more power (AT or BT). If only AF power is provided, it's likely not enough for both the AP and the attached device.
