Configuring PoE Properties

The PoE Properties page enables selecting either the Port Limit or Class Limit PoE mode and specifying the PoE traps to be generated.

These settings are entered in advance. When the PD actually connects and is consuming power, it might consume much less than the maximum power allowed.

Output power is disabled during power-on reboot, initialization, and system configuration to ensure that PDs are not damaged.

To configure PoE on the switch and monitor current power usage:

  1. Click Port Management > PoE > Properties. The PoE Properties page opens.
  2. Enter the values for the following fields:
    • Power Mode--Select one of the following options:
      • Port Limit--The maximum power limit per each port is configured by the user.
      • Class Limit--The maximum power limit per port is determined by the class of the device, which results from the Classification stage.
    • Traps--Enable or disable a SYSLOG trap.
    • Power Trap Threshold--Enter the usage threshold that is a percentage of the power limit. An alarm is initiated if the power exceeds this value.

    The following counters are displayed:

    • Nominal Power--The total amount of power the switch can supply to all the connected PDs.
    • Consumed Power--Amount of power currently being consumed by the PoE ports.
    • Available Power--Nominal power - the amount of consumed power.
  3. Click Apply to save the PoE properties.
