2.1Power Management
When establishing a network, the total power required by PDs may exceed the total power available from the Midspan. The
Sometimes, connected operating PDs significantly increase or suddenly raise their power requirements. If the required power exceeds the available power, the Power over Ethernet Midspan starts to turn off ports in accordance with their priority (the first turned off port is the lower priority port) until the total power is once again under the maximum limit. Default priority is establishid by port number: the higher the port number is, the lower priority it gets.
