Power over Ethernet (PoE) function
The PoE function allows the power supply of connected Ethernet devices via the Ethernet
cable so that the end device does not need a separate power supply.
Per PoE port of the PSE (Power Sourcing Equipment), a maximum of 15.4 W power are
available according to the 802.3af standard.
Note
With a 100 m long cable connected, the end device then has a maximum of 12.95 W
available.
You will find more information on the PoE function in the section "TP ports (Page 20)".
