3.3 Installation Precautions of Local Power
The 6-contact terminal block connector on the upper panel of LRP injector is used
for two DC redundant power inputs. Please follow the steps below to insert the
power wire.
Note
1. When an external power supply and Ultra PoE switch are
connected at the same time, the LRP-201HT will give priority to
higher voltage of power source. Both data and power are then
transmitted to the LRP-201ET.
2. If the input voltage is the same as the external power supply and
Ultra PoE switch, the power loading will be balanced.
Caution
When performing any of the procedures like inserting the wires or
tightening the wire-clamp screws, make sure the power is OFF to
prevent from getting an electric shock.
1. Insert positive and negative DC power wires into contacts 1 and 2 for POWER 1,
or 5 and 6 for POWER 2.
