PoE

PoE

The PoE configurations include global parameters, interface parameters, and PoE device information.

The switch supports the Power Over Ethernet (PoE) function. After being configured with the PoE power supply, the switch can provide 48 V DC power for the remote powered device (PD) such as the IP phone, WLAN AP, and network camera through the twisted pair.

Only the product models with "PWR" in the product names support the PoE function.

Global Parameter Settings

You can set global PoE parameters.

Context

Currently, the network devices are deployed flexibly; therefore, the cabling of power supply is complicated. To simplify cabling, you can configure the PoE function on the switch.

Procedure

  1. Choose System Management > PoE > Global Parameter Settings in the navigation tree to open the Global Parameter Settings page, as shown in Figure 2-53.

    Figure 2-53  Global Parameter Settings

    Table 2-20 describes the parameters on the Global Parameter Settings page.

    Table 2-20  Global Parameter Settings

    Parameter

    Description

    Power Supply Management Mode

    Indicates the mode of power supply management:
    • Auto

      When providing power at almost full capacity, the switch provides power first for the PD connected to the interface of the highest priority and powers off the PD connected to the interface of the low priority.

    • Manual

      When providing power at almost full capacity, the switch keeps the original power supply way, even if a new PD is connected to an interface with high priority.

    By default, the power supply is in automatic mode.

    Max Output Power

    Indicates the maximum output power of an interface.

  2. Set the parameters.
  3. Click Apply to complete the configuration.

Interface Parameter Settings

You can set the PoE parameters on an interface.

Context

  • Currently, the network devices are deployed flexibly; therefore, the cabling of power supply is complicated. To simplify cabling, you can configure the PoE function on the switch.
  • By default, the PoE function is enabled on all interfaces.

Procedure

  • Query power supply information on interfaces.
    1. Choose System Management > PoE > Interface Parameter Settings in the navigation tree to open the Interface Parameter Settings page.
    2. Select an interface type from the drop-down list box.
    3. Enter the interface number, for example, 0/0/1 (stack ID/sub-card ID/port number).
    4. Click Query to display all matching records.
  • Set power parameters on an interface.
    1. Choose System Management > PoE > Interface Parameter Settings in the navigation tree to open the Interface Parameter Settings page.
    2. Select a record and click Configure. The Configure Power Parameters on Interface page is displayed, as shown in Figure 2-54.

      Figure 2-54  Configure Power Parameters on Interface

      Table 2-21 describes the parameters on the Configure Power Parameters on Interface page.

      Table 2-21  Configure Power Parameters on Interface

      Parameter

      Description

      Interface Name

      Indicates the name of an interface. The interface name cannot be modified. You can select multiple interfaces each time.

      If only one interface is selected, the configuration of the interface is displayed on the Configure Power Parameters on Interface page. If multiple interfaces are selected, the default settings of the interfaces are displayed.

      Enable POE on Interface

      Indicates whether to enable the PoE function on the interface. The options are Enable and Disable.

      By default, the PoE function is enabled. The PoE parameters take effect only after the PoE function is enabled.

      Max Output Power

      Indicates the maximum output power of an interface.

      Power Priority

      Indicates the power priority of an interface. The options are Low, High, and Critical.

      By default, the power priority of a PoE interface is low.

      Manual Power Supply

      Indicates the manual power supply mode. The options are power on and power off.

      You can manually power on and power off the PD connected to an interface.
      NOTE:
      Before powering on or off a PD, ensure that:
      • The PD is connected to an interface.
      • The PoE function is enabled on the interface.
      • If the PD on an interface has been powered on, an error message is displayed after you power on the PD again.
      • If the PD on an interface has been powered off, an error message is displayed after you power off the PD again.

    3. Set the parameters.
    4. Click OK.

PoE Power Supply Information

You can view PoE information.

Context

None.

Procedure

  1. Choose System Management > PoE > PoE Power Supply Information in the navigation tree to open the PoE Power Supply Information page, as shown in Figure 2-55. The PoE information is displayed. If the PoE information is modified, the latest PoE information is displayed.
