SoundTube STNet-Switch 16-Port 40W PoE Switch

The STNet-Switch is an intelligent audio grade 16 port, proprietary 40w PoE, CobraNet-network Switch. The STNet-Switch allows users to connect up to 16 SoundTube IP speakers via Cat-5 and power them using the internal 40w PoE. Expansion beyond 16 speakers can be done one of three ways; with additional STNet-Switches, using a PoE+ switch or using a non-powered switch with local power. The Switch has 2 non-powered gigabit ports for high speed expansion and a WAN port for external communication. The Switch has a built in DHCP server for IP assignment which it uses to identify each end point on the CobraNet network.

It constantly monitors the health of the SoundTube network and speakers and reports if it detects faults. The switch has visual fault indicators on the front panel and 2 contact closure ports on the rear for external audible and visual fault alarms. It also has the ability to send an email, either at user preferred intervals indicating the system is operating normally or immediately upon detection of a fault. The system monitors PoE power, endpoints on the network and 3 variables on the speakers: the voice coil, operating temperature and the amplifier.
