Using a non-configurable switch with a sufficient number of ports guarantees the
stability of the system even if several amplifiers fail. If the switch malfunctions, you
cannot reach any amplifier.
3. Simple Redundancy: Malfunction of one amplifier, small managed switch
If two ports of a managed switch are available, you can set up a simple ring. You must
configure the switch accordingly. By doing this, even if one device malfunctions, all others
are reachable. If the switch malfunctions, you cannot reach any amplifier.
Please ensure that all amplifiers are connected to the electric circuit. Otherwise, the
network signals cannot be passed on via the integrated switch.
4. Multiple Redundancy with Switch, two large switches (managed)
Double star-shaped cabling with two configurable sufficiently sized switches provides
operating safety if one switch and any number of amplifiers fail.
The TOPAS' controller (DSP/network) is equipped with its own power supply unit that
is independent of the main power supply. This ensures safe operations of the network
connections even if the main power supply fails (overload, overheating).
