Device variants with ports on the rear have the following properties:
On the device. there are 16 LED display elements for the port status of
the 1-Gigabit Ethernet ports as well as 6 LED display elements to display
the device status. The LED display elements are located on the front side
of the device.
The supply voltage connection and the ports are located on the rear side
of the device. The device has 16 × 1-Gigabit Ethernet ports as well as
1 additional Fast Ethernet port on the front side of the device, which can
be used for diagnostic purposes.
1.3.1 Support of PoE
The MAR1042... and MAR1142... devices support PoE (Power over
Ethernet) according to 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 device variants provide 4 × 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 per port.
The 4 PoE-capable ports are the 4 first ports of the device (Port 1 ... 4, see
table 3 on page 20 and table 5 on page 22). The PoE ports are marked 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:
