Power over Ethernet IEEE 802.3af:
IEEE 802.3af defines two types of power source equipment:
end-span and mid-span.
• End-span refers to an Ethernet switch with embedded
Power over Ethernet technology. These new switches
deliver data and power over the same wiring pairs -
transmission pairs 1/2 and 3/6.
Mid-span devices resemble patch panels. They are placed
between legacy switches and the powered devices. Each of
the mid-span ports has an RJ-45 data input and data/power
RJ-45 output connector. Mid-span devices tap the unused
wire pairs 4/5 and 7/8 to carry power, while data runs on the
other wire pairs.
Digi One IAP and PortServer TS P MEI and are mid-span and
end-span.
Typical: 4 watts
Max: 6 watts
