Configuring PoE (J-Web Procedure)

Note:

This topic applies only to the J-Web Application package.

PoE (and PoE+) ports supply electric power over the same ports that are used to connect network devices to EX Series switches. You can use these ports 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.

Note:

For EX4400 switches, only EX4400-48MP and EX4400-24MP switches support PoE.

This topic includes:

Configuring PoE on EX2200, EX2200-C, EX3200, EX3300, EX4100, EX4100-F, EX4100-H, EX4200, and EX4400 Switches

To configure PoE:

Note:

For EX4400 switches, only EX4400-48MP, EX4400-24MP, EX4400-48XP, and EX4400-48MXP switches support PoE.

  1. Select Configure > Power over Ethernet.

    The page displays a list of all PoE-capable 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:

    If you are configuring a Virtual Chassis, the PoE configuring option is displayed if any member of the Virtual Chassis supports PoE, even if the Virtual Chassis primary does not support PoE.

    Note:

    After you make changes to the configuration on 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. Select one of the following options:

    • 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 1: PoE Edit Settings

Field

Description

Your Action

Enable PoE

Specifies that PoE is enabled on the interface.

Select this option to enable PoE or PoE+ on the interface.

Priority

Lists the power priority (low or high) configured on the interface enabled for PoE.

Set the priority as High or Low.

Maximum Power

Specifies the maximum PoE wattage available to provision the active PoE interface on the switch.

Select a value in watts. If no value is specified, the default is 15.4 for PoE interfaces and 30.0 for PoE+ interfaces.

EX4400-48MP, EX4400-24MP, EX4400-24X, EX4400-48XP, and EX4400-48MXP, and EX4100-H switches support up to 90 W using 802.3 bt.

Note:

EX4100 and EX4100-F switches does not support this option.
Table 2: System Settings

Field

Description

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 the powered device that is connected to the switch on the PoE port. When the power management mode is set to static, you can specify the maximum power for each PoE interface.

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

Guard Band (watts)

Specifies the amount of power reserved for power spikes from the PoE power budget of the switch.

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

Configuring PoE on EX6200 Switches

To configure PoE:

  1. Select Configure > Power over Ethernet.

    The page displays a list of all PoE-capable interfaces for each FPC. 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 on 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 (J-Web Procedure) for details about all commit options.

  2. Select one of the following options:

    • Edit—Changes PoE settings for the selected port as described in Table 3.

    • FPC Settings—Changes PoE settings of PoE-capable FPCs.

      To configure FPC settings, select one of the following options:

      • Add—Adds a PoE setting for an FPC as described in Table 4.

      • Edit—Modifies a PoE setting for an FPC as described in Table 4.

      • Delete—Deletes an existing PoE settings for an FPC.

Description

Your Action

FPC

Specifies the FPC number.

Select a value from the list.

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 for the interface that is connected to the switch on the PoE port. When the power management mode is set to static, you can specify the maximum power for each PoE interface.

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

Guard Band (watts)

Specifies the amount of power reserved for power spikes from the PoE power budget of the switch.

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

Maximum Power

Specifies the maximum PoE wattage available to provision active PoE ports on the FPC. For example, if you specify 1000 W, the PoE controller is limited to a power budget of 1000 W to distribute to the PoE ports.

Select a value in watts.
