Setting up the conference system
Setting up large conference system comprising ADN PS power supplies conference units connected in redundant ring topology
In large conference systems with up to 400 conference units, the redundant ring topology ensures that, should one conference unit or system cable fail or be manipulated, all other conference units of the cable ring will continue to function reliably. When the conference units are connected in ring topology, one ADN PS power supply can power approx.
To ensure full operational reliability in a redundant ring topology, the hardware of the ADN C1 and ADN D1 has been revised. If you combine conference units with hardware revision 1 (no marking on the type plate) and conference units with hardware revision 2 (“HW: v2” is printed on the type plate),
In a redundant ring topology, only use conference units with hardware revision 2.
