Ethernet ports
You can connect end devices and other segments to the device ports using
twisted pair cables or optical fibers (F/O).
Note:
By using media modules, you obtain up to 8 additional Fast Ethernet
ports.
1.6.1
Basic device
Gigabit combo port
The GREYHOUND device provides 4 combo ports for transmission
speeds of up to 1000 Mbit/s.
See “General technical data” on page 60.
You have the option of alternatively connecting a twisted pair cable via a
RJ45 socket or an optical fiber via a SFP transceiver to a combo port.
You obtain appropriate SFP transceivers as an accessory.
By inserting an SFP transceiver, you automatically deactivate the
assigned twisted pair port.
10/100/1000 Mbit/s twisted pair port
This port is an RJ45 socket.
The 10/100/1000 Mbit/s twisted pair port allows you to connect network
components according to the IEEE 802.3 10BASE-T/100BASE-TX/
1000BASE-T standard.
This port supports:
Autonegotiation
Autopolarity
Autocrossing (if autonegotiation is activated)
1000 Mbit/s full duplex
100 Mbit/s half-duplex mode, 100 Mbit/s full duplex mode
