·  | • Low priority port will be shutdown. When a newly | 
  | powered device is connected, the switch searches  | 
  | among its currently connected and powered devices. If  | 
  | any port has lower priority than the newly connected  | 
  | port, the switch discontinues the power supply to the  | 
  | lower priority port and provides power to the newly  | 
  | connected port. If this power budget from disabling  | 
  | one low priority port is not enough, the switch disables  | 
  | the next low priority port and so on until the power  | 
  | budget is enough. If there are no low priority ports or  | 
  | not enough power, the newly connected device is not  | 
  | powered. | 
Power Usage Threshold: | The Power Usage Threshold is the threshold to enable the | 
  | SNMP trap. The default value is 80% and is configurable by the  | 
  | administrator. If the power budget is consumed, an SNMP trap  | 
  | is sent to the associated receivers. If an SNMP trap receiver is  | 
  | defined, no SNMP trap is sent. |
