1.5 Ethernet ports
You have the option to connect terminal devices or other segments to the
ports of the media modules via twisted-pair cables or F/O cables.
1.5.1 100 Mbit/s F/O port
This port is an SFP slot or an ST or DSC socket.
See “Accessories” on page 32.
The 100 Mbit/s F/O port offers you the ability to connect network components
according to the IEEE 802.3 100BASE-FX standard.
This port supports:
 100 Mbit/s half-duplex mode, 100 Mbit/s full duplex mode
Default setting: Full duplex
Applies to device variants with DSC ports or ST ports:
When connecting the data cables, note the sending and receiving directions.
1.5.2 10/100 Mbit/s twisted pair port
This port is an RJ45 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 (if autonegotiation is activated)
 100 Mbit/s half-duplex mode, 100 Mbit/s full duplex mode

10 Mbit/s half-duplex mode, 10 Mbit/s full duplex mode
Delivery state: autonegotiation active
The socket housing is electrically connected with the front panel.
