over standard UTP Ethernet cables. The Switch follows the

standard PSE (Power Sourcing Equipment) pinout, whereby

power is sent out over pins 1, 2, 3 and 6.

PoE parameters are assigned to the powered device that is

connected to the selected port.

State:

• Enable – Enables the Device Discovery protocol and provides

power to the device using the PoE module. The Device Discovery

Protocol lets the device discover powered devices attached to

deviceinterfacesandlearnstheirclassication.

• Disable – Disables the Device Discovery protocol and halts

the power supply delivering power to the device using the PoE

module.

Priority:

Selecttheportpriorityifthepowersupplyislow.Theeld

default is Low. 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.Thepossibleeldvaluesare:4.

• Low – Sets the PoE priority level as low.

• Medium – Sets the PoE priority level as medium.

• High – Sets the PoE priority level as high.

• Critical – Sets the PoE priority level as critical.
