2.5 Set The PoE Class Of The Power Supply
Mx2wire+ always logs on as a PoE class 0 device (0.44–12.95W) and supplies the connected
end device with up to 7.5W of power (up to PoE class 2), depending on cable length and
type, when using a PoE class 0 injector/switch.
End devices can be supplied with up to 13W of power (up to PoE class 3) when using a more
powerful PoE+ class 4 injector/switch (12.95–25.5W). It is possible to achieve this value if a
power supply unit with the specification 48–57VDC, 600mA is used for the power supply.
Important
When connecting a PoE+ class 4 injector/switch (12.95–25.5W), the PoE rotary switch
on the Mx2wire+ circuit board connected to the injector/switch needs to be switched
to 4 (from 3) in order to make use of the full potential of PoE+.
The standard setting 3 is selected for power supply:
• via PoE injector/switch (class 0 or 3, max. 12.95W)
• via MOBOTIX NPA-PoE set
• via power supply unit (48–57VDC, 600mA)
Changing The PoE Class (From 3 To 4):
1. Loosen the screws in the front panels (item 1.2) and
lift the panels forwards.
2. Using a small screwdriver, switch the rotary switch
on the Mx2wire+ connected to the injector/switch
from position 3 to position 4 (see figure). This setting
corresponds to the PoE classes 3 and 4 of the injector/
switch used.
The PoE classes 1 and 2 are generally not selected
because Mx2wire+ already requires 2 x 3 watts for
its own consumption (PoE class 1 for each unit) and
if a single class 1 or 2 injector/switch is connected to
the sender unit, there would be no power for the Mx2wire+ receiver unit or an
end device.
3. The front panel does not need to be screwed back on until installation is complete
(see the following pages).
