NOTE:
A port with a smaller port ID has a higher priority for getting power. When the PoE power reaches the
guard band and a new port requires power, the switch compares the port IDs and performs one of the
following actions:
•
Does not supply power to the new port if the ID of the new port is greater than IDs of all existing ports.
•
Stops power supply to existing ports whose IDs are greater than the ID of the new port, and supplies
power to the new port.
