1.4 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.
Connect the ports of the media modules plugged into the basic device as 
required in order to set up your industrial Ethernet or expand your existing 
network.
1.4.1 100 Mbit/s F/O port
This port is an SFP slot.
See “Accessories” on page 35.
The 100 Mbit/s F/O port allows you 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
Note: Insert the RSPM20-4Z64Z6... media module in the media module 
slot 2 only.
See “Media module slots on the RSPE device” on page 20.
1.4.2 10/100 Mbit/s twisted pair port
This port is an RJ45 socket.
The 10/100 Mbit/s twisted pair port allows you 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 activated
The port casing is electrically connected to the front panel.
