PoE budgeting
The PoE budget (Power over Ethernet) limits the amount of power available to all ports, with a maximum of 30W on an individual port. Add the total number of possible watts that the connected devices can consume to make sure everything can receive power reliably. Below is an example that uses an AN-320-SW-R-8-POE.
Total PoE budget available = 130W
Total PoE device consumption = 42W
PoE budget left available = 88W
