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. 30-40 conference units.
Connecting conference units
connected in a cable ring to the
ADN PS power supply
The following describes how to connect one cable ring to an ADN PS power supply.
If necessary, repeat these steps for a second cable ring and additional ADN PS
power supplies.
왘
Connect the required number of ADN PS power supplies to the ADN CU1 central
unit (see page 10).
왘
Use a system cable to connect output
1
of the
PORT I
socket of the ADN PS
power supply to the
IN
socket
of the first conference unit.
왘
Use a system cable to connect the
OUT
socket
of the first conference unit to
the
IN
socket
of the second conference unit.
왘
Repeat these steps for additional conference units.
왘
Use a system cable to connect the
OUT
socket
of the last conference unit in
the cable ring to output
2
of the
PORT I
socket of the ADN PS power supply.
왘
If necessary, repeat all steps for a second cable ring on
PORT II
and the
additional ADN PS power supplies.
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), fail-safe operation is only possible to a limited extent.
왘
In a redundant ring topology, only use conference units with hardware
revision 2.
