Power Over Ethernet (Poe) - Power Supply Via The Lan Cable - Hirschmann BAT54-F User Manual

Warning
For safety reasons the devices have been designed to operate at
low voltages. Thus, they may only be connected to the supply
voltage connections and to the signal contact with SELV circuits
with the voltage restrictions in accordance with IEC/EN 60950-1.

2.11.3 Power over Ethernet (PoE) -
power supply via the LAN cable
Hirschmann Wireless Routers are prepared for the PoE (Power over
Ethernet) procedure and conform to the 802.3af standard. PoE-capable
network devices can be supplied with power via the LAN cable. This makes
it unnecessary to have a separate power supply for every base station, thus
considerably reducing the work involved in the installation.
In the BAT-F devices, the voltage is input via the wire pairs transmitting the
signal (IEEE 802.3af, mode A).
In the BAT-Rail devices it is also possible to supply the voltage via the free
wire pairs.
The power supply to the LAN is input centrally, or via a PoE injector or a
power hub/power switch.
Warning
In a PoE installation, only use devices that adhere to the 802.3af
standard! No warranty claims can be made for damage caused by
the use of impermissible devices.
