Properties

Note

This section is only relevant for devices supporting PoE.

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 aren’t damaged.

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

Procedure

Step 1

Click Port Management > PoE > Properties.

Step 2

Enter the values for the following fields:

  • Power Mode—Select one of the following options:

    • Class Limit—Maximum power limit per port is determined by the class of the device, which results from the Classification stage.

    • Port Limit—Maximum power limit per each port is configured by the user.

      Note

      When you change from Port Limit to Class Limit or conversely, disable the PoE ports, and enable them after changing the power configuration.

  • Traps—Enable or disable traps. If traps are enabled, you must also enable SNMP and configure at least one SNMP Notification Recipient.

  • 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 for the device:

    • Operational Status—Displays the operational status (Normal or Fault) of the PoE switch.

    • Nominal Power—Total amount of power the device can supply to all the connected PDs.

    • Consumed Power—Amount of power currently being consumed by the PoE ports.

    • Available Power—Nominal power minus the amount of consumed power.

  • Software Version—Displays the software version of the PoE chip.

  • PSE Chipset & Hardware Revision—PoE chipset and hardware revision number.
