100 MBit/s F/O ports enable the connection of terminal devices or indepen-
dent network segments in compliance with the IEEE 802.3 100BASE-FX
standard.
These ports support:
Full or half duplex mode
Default setting: Full duplex
1.4.3 1000 Mbit/s F/O port
This port is an SFP slot.
1000 Mbit/s F/O ports enable the connection of terminal devices or indepen-
dent network segments according to the IEEE 802.3 1000BASE-
SX/1000BASE-LX standard.
These ports support:
Autonegotiation
Full duplex mode
Delivery state: autonegotiation active.
1.4.4 PoE ports
The MACH104-20TX-F-4PoE... device variants support Power over Ethernet
(PoE) in accordance with IEEE 802.3af.
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 following applies to PoE ports:
Max. Powered Device (PD) class 0 (15.4 W)
The PoE power is supplied via the wire pairs transmitting the signal
(phantom voltage).
The individual ports (joint PoE voltage) are not electrically insulated from
each other.
1.4.5 Combo ports
You have the option to alternatively connect F/O (via SFP transceivers) or
twisted pairs to a combo port.
When you are using an SFP transceiver, you get an optical interface. You
thus deactivate the corresponding TP interface.
Ports PoE support
1 to 4 Yes
5 to 20 No
