1.1.4 PoE ports
The MACH104-20TX-F-4PoE device variants support Power over Ethernet
(PoE) in accordance with IEEE 802.3af.
They allow the connection and remote supply of, for example, IP telephones
(Voice over IP), webcams, sensors, printer servers and WLAN access points
via 10BASE-T/100BASE-TX/1000BASE-T. With PoE, these terminal devices
are powered by the twisted-pair cable.
The MACH104-20TX-F-4PoE provides four 10BASE-T/100BASE-TX/
1000BASE-T ports (RJ45 sockets) for connecting network segments or PoE
terminal devices (PD, Powered Device) for all IEEE802.3af classes up to a
maximum power output of 15.4 W.
The 4 PoE-capable ports are the 4 first ports on the device (ports 1 to 4, see
figure in chapter
„MACH104 devices with 24 GB ports, 4 of which are PoE
ports“ on page 14 . The PoE ports are indicated with the red PoE logo on the
device.
The current is supplied on wire pairs transmitting the signal; the individual
ports are not electrically insulated from each other.
The following conditions are met in accordance with IEEE 802.3af:

1.1.5 Combo ports
At the four Gigabit ETHERNET combo ports (see fig. 4 and fig. 5 ) you can
connected either F/O (via SFP modules) or twisted pair.

SFP modules
SFP modules are optical transceivers (Fast ETHERNET and Gigabit
ETHERNET SFP modules, see page
page 35 ). SFP stands for Small
Form-factor Pluggable and is also frequently referred to as mini-GBIC (Gi-
gaBit Interface Converter).
The SFP modules are plugged into the SFP slots of the MACH104 device
in order to obtain an F/O port. The MACH104 has four TP interfaces and
four slots for inserting SFP modules (100/1000 Mbit/s).
By inserting the SFP module you deactivate the corresponding TP inter-
face.
