5.3 Installation Precautions of Local Power
Installation of LRP injector or LRP switch. If you need to increase the PoE
power budget of the LRP-104CET, you must use an external DC power supply.
The 6-contact terminal block connector on the upper panel of LRP Extender
is used for two DC redundant power inputs. Please follow the steps below to
insert the power wire.
Note
When the user is connected with an external power supply,
the LRP-104CET will give priority to external power supply, LRP
Injector or LRP Switch where data is transmitted to the LRP-
104CET.
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.
