1.3.8
Support of PoE
The MACH 1000 device variants MAR1022-..., MAR1032-...,
MAR1132-... and MAR 1132-... 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. With PoE,
these terminal devices are powered by the twisted-pair cable.
The MACH 1000 devices with PoE have 2 × 2 twisted pair ports TX 10/
100 Mbit/s, depending on the device variant, as RJ45 or M12 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 current is supplied on wire pairs transmitting the signal; the individual
ports are not electrically insulated from each other.
The following conditions are met in accordance with IEEE 802.3af:
Endpoint PSE
Alternative A
The port casing is electrically connected to the front panel.
The PoE power is supplied via the wire pairs transmitting the signal (phantom
voltage).
Use a shielded CAT5 cable or better.
Use a shielded 4-pin M12 plug.
Connect the cable shield to the connector housing.

a. In devices without PoE, power supply unit 2 is optional. It is used for redundant voltage
supply. In devices with PoE, power supply unit 2 is mandatory. It is only used to supply PoE
voltage to the connected devices.
b. For devices with PoE that have plugged connections, power supply unit 2 must be
SignalSignal “M”.
