Any configuration changes made locally on the switch won't be synchronized with Sophos Central. We recommend making changes from the Sophos Central control panel instead.

PoE

The PoE tab lets you manage the power budget for the switch's power supply and individual PoE port settings.

Power Budget

You can set and monitor the total power available from the switch.

Total power budget lets you enter the amount of power the Switch can provide to all PoE ports.

Consumed power shows the total power the switch delivers to all PoE ports.

PoE port settings

The PoE port settings tab shows the switch's PoE port settings. You can sort each setting by clicking the column header.

To change the PoE settings for the switch's ports, select the ports you want to configure and click Edit. Make your changes, then click Apply to save the settings.

The PoE port settings are as follows:

  • Port: The number of the port on the switch. The switch assigns these PoE parameters to the powered device connected to the selected port.

  • Status: This shows whether LLDP is turned on or off for the specified port. LLDP lets the switch discover powered devices and learn their classification.

    • On: LLDP is on, and the port provides power to the powered device.
    • Off: LLDP is off, and the port has stopped delivering power to the powered device.

  • Priority: Select the port priority. The priority helps the switch decide which ports to power when the power supply is limited. For example, if the power supply runs at 99% usage, and Port 1's priority is high, but Port 6's priority is low, then Port 1 is prioritized to receive power, and the switch may stop powering Port 6. Choose from the following settings:

    • Low: These ports are the first to have PoE power turned off when the power supply is limited.
    • Medium: The default setting. The switch stops powering these ports if it's still low on power after turning off all low-priority ports.
    • High: The switch stops powering these ports if it's still low on power after turning off all low-priority and medium-priority ports.
    • Critical: When the power supply is limited, the switch maintains power for these ports by turning off PoE power for all other ports in order of priority.

  • Power limit type: Choose how the switch limits PoE to individual ports. Choose from the following settings:

    • Autoclass: The switch assigns a class to the port that defines the maximum power it can provide to the powered device.
    • User defined: Lets you manually set the User Power Limit (W).

  • User power limit (W): The maximum power the switch can deliver to the specified port in watts.

  • Status: Shows the port's PoE status. It can be one of the following statuses:

    • Searching: The default status. The switch is currently searching for a powered device.
    • Delivering: The port is delivering power to the powered device.
    • Disabled: PoE is turned off for the specified port.
    • Testing: The switch is testing the powered device. For example, to confirm a powered device receives power from the power supply.
    • Test Fail: The powered device has failed the test. For example, a port can't have PoE turned on and can't deliver power to the powered device.
    • Fault: The switch has detected a fault on the powered device when it forces the port on. For example, if the power supply voltage is out of range, a short occurs, or a communication error with the powered devices occurs.

  • Signature: Shows whether the powered device is a Single or Dual signature.

  • Mode-A/Mode-B class: Shows the maximum power the Power Sourcing Equipment can deliver to the powered device. The maximum power for each class is as follows:

    • Class 0: 15.4 watts.
    • Class 1: 4.0 watts.
    • Class 2: 7.0 watts.
    • Class 3: 15.4 watts.
    • Class 4: 30 watts.
    • Class 5: 45 watts.

You can choose additional PoE information to show on the PoE port settings tab. Click the ellipsis Ellipsis. and select the information you want to show from the following options:

  • Mode-A/Mode-B power (W): Shows the power, in watts, consumed by the powered device.
  • Total power output (W): The total power, in watts, being delivered to the powered device.
