Check each port and the total
List the maximum power requirement and PoE standard for every device. Verify that each assigned port supports the device and that the switch can supply the total for the chosen power configuration.
Work through an example
If eight cameras each need 12 W and four access points need 20 W each, the device total is 176 W. Compare the switch’s allocations with that estimate and leave room for additional devices or higher draw when features such as infrared lighting activate.

Frequently asked questions
Does a free Ethernet port mean I have enough power?
Check whether the port supplies the required PoE class and whether the switch still has enough power to allocate.
