A network technician is deploying 30 IP phones and 6 wireless access points from a single access switch. Each phone requires up to 7W and each access point requires up to 25.5W. The switch specification sheet lists a total PoE power budget of 370W. After connecting all devices, several access points fail to power on. What is the MOST likely cause?
