Putting the conference system into operation
Connecting ADN PS power supplies to the ADN CU1 central unit
For conference systems comprising more than 40 conference units or when the
conference units are connected in a redundant ring topology, you require ADN PS
power supplies. A max. of 15 ADN PS power supplies can be used in a conference
system.
왘 Use a system cable to connect the PORT II socket or PORT I socket of the
ADN CU1 central unit to the DATA CU/PS input socket of the first ADN PS
power supply (shorter cables increase the operational reliability, the maximum
length allowed is 80 m).
왘 Use a system cable to connect the DATA PS output socket of the first ADN PS
power supply to the DATA CU/PS input socket of the second ADN PS power
supply.
왘 Repeat these steps for the remaining ADN PS power supplies.
