Overview of the PoE+ settings of a Linksys Managed PoE+ Gigabit Switch

The PoE+ settings page of your Linksys Managed PoE+ Gigabit Switch contains PoE subsystem information for monitoring the current power usage and assigns the total amount of power the switch can provide to all of its PoE+ ports.

If the images you see or the steps you follow look different from the actual page, here are
alternative instructions/information.

To access this page, follow the steps below:

1. Access the web interface of your switch.

2. Click on PoE+ under the System menu.

Options may differ depending on the model number of your switch.

PoE+ Port Settings
 

Power Budget
 
  • Total Power Budget: This allows you to enter the amount of power the switch can provide to all ports.
  • Consumed Power: Displays the total amount of power (in Watts) that’s currently being delivered to all PoE+ ports.
 
The total power budget will differ for every Linksys Managed PoE+ Gigabit Switch.

  • Port: Displays the specific port number for which PoE parameters are defined. PoE parameters are assigned to the powered device that is connected to the selected port.
  • State: Disable or enable PoE on the port. By default, all ports are PoE-enabled.
  • Priority: Select the port priority if the power supply is Low. The default is Medium. For example, if the power supply is running at 99% usage, and port 1 is prioritized as High, but port 6 is prioritized as Low, port 1 is prioritized to receive power and port 6 may be denied power.
 
  • Low: Sets the PoE priority level to low.
  • Medium: Sets the PoE priority level to medium.
  • High: Sets the PoE priority level to high.
  • Critical: Sets the PoE priority level to critical.
 
  • Power Limit Type: Shows the classification of the connected powered device. The class defines the maximum power that can be provided to the powered device. 
 
To change the Power Limit Type, select a port, then click the drop-down menu to select Auto Class at the top of the column or User defined. If needed, manually set a user power limit, and click Apply.

The possible field values are:

 
  • Class 0: The maximum power level at the Power Sourcing Equipment is 15.4 Watts.
  • Class 1: The maximum power level at the Power Sourcing Equipment is 4.0 Watts.
  • Class 2: The maximum power level at the Power Sourcing Equipment is 7.0 Watts.
  • Class 3: The maximum power level at the Power Sourcing Equipment is 15.4 Watts.
  • Class 4: The maximum power level at the Power Sourcing Equipment is 30 Watts.
  • Class: Select this option to base the power limit on the value configured in the User Power Limit field.
  • Auto Class: Auto Class means the power limit is based on the class, which PSD (switches) detects on the PD device.
 
  • User Power Limit (W): Select this option to base the power limit on the value configured in the User Power Limit field.
  • Status: Shows the port's PoE status.
 
The possible field values are:
 
  • Delivering Power: The device is enabled to deliver power via the port.
  • Disabled: The device is disabled for delivering power via the port.
  • Test Fail: The powered device test has failed. For example, a port could not be enabled and cannot be used to deliver power to the powered device.
  • Testing: The powered device is being tested. For example, a powered device is tested to confirm if it is receiving power from the power supply.
  • Searching: The device is currently searching for a powered device. Searching is the default PoE operational status.
  • Fault: The device has detected a fault on the powered device when the port is forced on. For example, the power supply voltage is out of range, a short circuit occurs, a miscommunication or a communication error with a PoE device, or an unknown error occurs.
