1.3.5 Support of PoE
The MAR1042/MAR1142 device variants support Power over Ethernet (PoE)
in accordance with IEEE 802.3af.
They allow the connection and remote supply of, for example, IP telephones
(Voice over IP), webcams, sensors, printer servers and WLAN access points
via 10BASE-T/100BASE-TX/1000BASE-T. With PoE, these terminal devices
are powered by the twisted-pair cable.
The MAR1042 and MAR1142 provide four 10BASE-T/100BASE-
TX/1000BASE-T ports (RJ45 sockets) for connecting network segments or
PoE terminal devices (PD, Powered Device) for all IEEE802.3af classes up
to a maximum power output of 15.4 W.
The 4 PoE-capable ports are the 4 first ports on the device (ports 1 to 4, see
figure 2 and figure 4). The PoE ports are indicated with the red PoE logo on
the device.
The PoE power is supplied via the wire pairs transmitting the signal (phantom
voltage).
The individual ports are not electrically insulated from each other.
The following conditions are met in accordance with IEEE 802.3af:
