Setting the Maximum Output Power on a Port
The maximum power that can be supplied by each Ethernet electrical port of a PoE-enabled S3100
switch to its PD is 15,400 mW. In practice, you can set the maximum power on a port depending on the
actual power of the PD, in the range of 100 to 15,400 mW and in the granularity of 1 mW.

Setting PoE Management Mode and PoE Priority of a Port
When a switch is close to its full load in supplying power, you can adjust the power supply of the switch
through the cooperation of the PoE management mode and the port PoE priority settings. S3100 series
switches support two PoE management modes, auto and manual. The auto mode is adopted by default.
z auto : When the switch is close to its full load in supplying power, it will first supply power to the PDs
that are connected to the ports with critical priority, and then supply power to the PDs that are
connected to the ports with high priority. For example: Port A has the priority of critical. When the
switch PoE is close to its full load and a new PD is now added to port A, the switch will power down
the PD connected to the port with the lowest priority and turn to supply power to this new PD. If
