The mid span PoE power sources, TP-MS4x4 are used for supplying PoE and data
to multiple devices from a central location such as an operations room or
equipment cabinet. The PoE devices feature a separate data-in port coupled with
a data out/PoE port. The PoE function is considered Passive PoE and supports
Gigabit Ethernet. The Midspan features Universal Voltage (UniVolt) PoE outputs
where the PoE voltage equals the input voltage. All ports can have the same PoE
voltage or you can assign different voltages to different ports. This is useful
for powering different devices with different PoE voltage requirements. The
Midspan also allows some or all PoE ports to be reverse voltage PoE which is
required by some Passive PoE devices like Canopy and EnGenius.
To supply different PoE voltages to each port you have to supply the unit
with the different DC voltages from external power supplies and configure
jumpers to route the correct voltage to the correct port.
PoE DC Voltage (11V-57V) is supplied on pins 4,5 (V+) and 7,8 (V-). Maximum
power output per port is 1A. The individual outputs are overcurrent, over/under
voltage and short circuit protected.
The midspan is DIN Rail mountable with the included DIN Rail brackets.
