The Settings page displays system PoE information for enabling PoE on the interfaces and
monitoring the current power usage and maximum power limit per port when the PoE mode is
Port Limit.
PoE can be configured on the device for a specific period. This feature enables you to define,
per port, the days in the week and the hours that PoE is enabled. When the time range is not
active, PoE is disabled. To use this feature, a time range must first be defined in the
page.
This page limits the power per port to a specified wattage. For these settings to be active, the
system must be in PoE Port Limit mode. That mode is configured in the
When the power consumed on the port exceeds the port limit, the port power is turned off.
PoE Priority Example:
Given: A 48 port device is supplying a total of 375 watts.
The administrator configures all ports to allocate up to 30 watts. This results in 48 times 30
ports equaling 1440 watts, which is too much. The device cannot provide enough power to
each port, so it provides power according to the priority.
The administrator sets the priority for each port, allocating how much power it can be given.
These priorities are entered in the PoE Settings page.
See System Settings for a description of the device models that support PoE and the maximum
power that can be allocated to PoE ports.
To configure PoE port limit settings:
Click Port Management > PoE > Settings.
Ports are displayed with relevant PoE information. These fields are described in the Edit page
except for the following fields:
• Administrative Power Allocation (mW)—Enter the amount of power that can be
allocated.
• Operational Status—Displays whether PoE is currently active on the port.
• PoE Standard—Displays the type of PoE supported, such as 60W PoE and 802.3 AT
PoE).
Select a port and click Edit.
