3.Powered Device (capacitor). If capacitor detection enabled is not selected for a global configuration, go to Power Not Provided (step 13). (this step is combined with next step to make the flow chart clearly).

4.Check the connected device requirement on power based on capacitor. If it is not a powered device, go to Power Not Provided (step 13).

5.Power Budget. Check the power budget. If there is enough power to support the new device, got to Over Power Threshold (step 10).

6.Priority Based. Check the Power Management Method. If Deny next port connection, regardless of priority is chosen, go to Power Not Provided (step 13).

7.Low Priority Existed. Check the existence of lower priority powered port. If not exists, go to Power Not Provided (step 13).

8.Disable power to low priority port. Discontinue the power supply to the found lower priority port.

9.Power Budget. Check the power budget. If there is not enough power, go to Low Priority Existed (step 7) to disable the next lower priority port (if one exists).

10.Over Power Threshold. Check the power threshold and used power. If the currently used power is lower than the threshold, go to Power Provided (step 12).

11.Issue SNMP Trap. An SNMP trap is triggered. The trap is sent based on the set up of trap receiver.

12.Power Provided. Power is provided to the connected port as requested. The power reserved to this port depends on the classification of the powered device. Go to End of Algorithm (step 14).

13.Power Not Provided. No power is provided to the connected port due to no power budget, not powered device, etc.

14.End of Algorithm.
