2-2-5. Notes When Confi guring System
Power supply to RCP
The power to the RCP-920/921 can be supplied via three methods of "PoE", "Via CCA-5 cable" and "Supplying power to
EXT I/O". A method of supplying power is automatically selected in the way that the power with the highest voltage has
priority.
When "PoE" is select to supply the power, calculate the power that can be supplied from the respective output terminal of
the equipment supplying power, and the total power that is required by each equipment. Use the equipment supplying
power that has the suffi cient power supply capacity. If another RCP is connected by the CCA-5 cable to an RCP that has
already been connected by PoE, total power may exceed the power supply capacity with PoE. Do not connect equipment in
such way.

Loop connection is prohibited
If two or more equipment that have already been connected to the same network are further connected each other by the
CCA-5 cable, a loop is created resulting in malfunction.
In the following connection, remove the CCA-5 cable, or remove the LAN cable from CCU/HDCU or RCP so that the
information transmission route should not create a loop.
