4.2.22 PoE Determination Flowchart

Power Budget:

Maximum power allowed for powered devices. 170W for the

 

ES3000 switch.

Detection Method:

The powered device detection method. Older devices could

 

contain a capacitor. If this option is disabled (default), capacitor

 

devices are not detected and powered. Newer devices are

 

detected regardless if the Detection Method option is enabled

 

or disabled.

Power Management Method: When the power budget is running out as more powered

 

devices connected to the system, the system needs an

 

algorithm to determine the power service for the next powered

 

device. It could potentially deny the service requested of the

 

new device or disable current connected devices to provide

 

power to the new device. Two options are given to the

 

administrator,

·

Deny next port connection, regardless of

 

priority: The switch keeps providing power to current

 

connected powered devices and ignores the requests

of the newly connected device. The priority set up of each port is ignored.
