Putting the conference system into operation Setting up the conference system CAUTION Product damage due to an unsuitable power supply! If you connect standard network devices with RJ 45 plugs (e.g. switches or network cards) to the connection sockets PORT I and PORT II, the network devices can be damaged due to an unsuitable power supply. ̈ Only connect ADN C1 and ADN D1 conference units to the connection sockets PORT I and PORT II. Basic information on the set-up of the conference system Regardless of the number of conference units and the room size, we recommend the following procedure for setting up the conference system: ̈ Plan the number of conference units required for your conference system. A total of 400 conference units can be used in a conference system (the number of ADN C1 chairperson units is limited to 10 max.). Always take the largest possible number of participants as a starting point. ̈ Plan if simple cabling is sufficient or if you require a redundant ring topology (see page 15). ̈ If necessary, calculate the number of ADN PS power supplies required (a max. of 15 ADN PS power supplies can be used in a conference system). ̈ If necessary, calculate the maximum length of the cabling in order to ensure that all conference units connected are supplied with sufficient voltage (see page 19). ̈ Place the ADN CU1 central unit and, if necessary, the ADN PS power supplies in the electrical equipment room. ̈ Place the conference units at the corresponding seats. ̈ Put out a sufficient number of SDC CBL RJ45 system cables in the required lengths (see "Accessories" on page 154). When connecting the conference units to an ADN PS power supply, you can mix different cable topologies as long as you ensure correct cabling and comply with the specifications (see page 32 and page 34).
