You can connect end devices and other segments to the device ports using
twisted pair cables or optical fibers (F/O).
You find information on pin assigments for making patch cables here:
“Pin assignments” on page 20
1.5.1 10/100 Mbit/s twisted pair port
This port is designed as an 4-pin M12 socket.
The 10/100 Mbit/s twisted pair port offers you the ability to connect network
components according to the IEEE 802.3 10BASE-T/100BASE-TX standard.
This port supports:
Autonegotiation
Autopolarity
Autocrossing
Delivery state: Autonegotiation activated
The socket housing is electrically connected with the device housing.
Note: Some of these ports also support Power over Ethernet (PoE).
See “10/100 Mbit/s PoE port” on page 19.

Installation OCTOPUS OS20/OS24 Unmanaged
Release 08 07/2015 19
1.5.2 10/100 Mbit/s PoE port
Some device variants support Power over Ethernet based on IEEE 802.3at
(PoE+) via a twisted pair:
The PoE ports allow the connection and remote supply of, for example, IP
telephones (Voice over IP), webcams, sensors, printer servers and WLAN
access points. With PoE, power is supplied to these terminal devices via the
twisted-pair cable.
The devices are supplied with PoE voltage (53 V DC safety low voltage) via
the internal voltage supply. The PoE voltage to the twisted-pair cables is
supplied via the wire pairs transmitting the signal (phantom voltage).
The total PoE power output is limited to 61.6 W.
