PoE Port Settings

The PoE Settings displays the system information for enabling PoE on the interfaces. It monitors the power usage and maximum power limit per port when the PoE mode is Port Limit. When the power consumed on the port exceeds the port limit, the port power is turned off.

To configure PoE settings, follow these steps:

Procedure

Step 1

Click Port Management > PoE > PoE Port Settings .

Step 2

Select a port and click Edit.

Step 3

Enter the value for the following field:

  • Interface—Select the port to configure.

  • PoE Administrative Status—Enable or disable PoE on the port.

  • Time Range—Select to enable.
  • Time Range Name—If Time Range has been enabled, select the time range to be used. Time ranges are defined in Time Range. Click Edit to go to the Time Range page.

  • Power Priority Level—Select the port priority: low, high, or critical, for use when the power supply is low. For example, if the power supply is running at 99% usage and port 1 is prioritized as high, but port 3 is prioritized as low, port 1 receives power and port 3 might be denied power.

  • Administrative Power Allocation—If the Power mode is Port Limit, enter the power in milliwatts allocated to the port (Range: 0 - 30000. Default: 30000).

  • Max Power Allocation—This field appears only if the Power Mode set in the PoE Properties page is Power Limit. Displays the maximum amount of power permitted on this port.

  • Power Consumption—Displays the amount of power in milliwatts assigned to the powered device connected to the selected port.

  • Class—Displays the class of the device, which indicates the maximum power level of the device.

    Class

    Maximum Power Delivered by Device Port

    0

    15.4 watt

    1

    4.0 watt

    2

    7.0 watt

    3

    15.4 watt

    4

    30.0 watt

  • Overload Counter—Displays the number of overload counters

  • Short Counter—Displays the number of short counters

  • Denied Counter—Displays the number of denied counters

  • Absent Counter—Displays the number of absent counters

  • Invalid Signature Counter—Displays the times that an invalid signature was received. Signatures are the means by which the powered device identifies itself to the PSE. Signatures are generated during powered device detection, classification, or maintenance.

Step 4

Click Apply. The PoE settings for the port are written to the Running Configuration file.
