Configuring PoE (J-Web Procedure)

Power over Ethernet (PoE) ports supply electric power over the same ports that are used to connect network devices to EX Series switches. These ports allow you to plug in devices that require both network connectivity and electric power, such as VoIP phones, wireless access points, and some IP cameras. Using the Power over Ethernet (PoE) Configuration page in the J-Web interface, you can modify the settings of all interfaces that are PoE-enabled.

To configure PoE:

  1. Select Configure > Power over Ethernet.

    The page displays a list of all interfaces except uplink ports. Specific operational details about an interface are displayed in the Details section of the page. The details include the PoE Operational Status and Port class.

    Note: After you make changes to the configuration in this page, you must commit the changes for them to take effect. To commit all changes to the active configuration, select Commit Options > Commit. See Using the Commit Options to Commit Configuration Changes for details about all commit options.

  2. Click one:
    • Edit—Changes PoE settings for the selected port as described in Table 1.
    • System Settings—Modifies general PoE settings as described in Table 2.

Table 2: System Settings



Your Action

PoE Management

Specifies the power management mode. The options are: static and class.

Note: When the power management mode is set to class, the maximum power value is overridden by the maximum power value of the class of power device that is connected to the switch on the PoE port.

By default the power management mode is static. Select class to change the power management mode.

Guard Band (watts)

Specifies the band to control power availability on the switch.

Enter a value to set the guard band value in watts. The default value is 0.
