As for a standard bus can only provide either 24Vdc or 12Vdc for supplying to additional systems, the Ethernet switch on bus need to meet the supplied voltage & vehicle environmental requirements in particular with high voltage clamp or surge protection when engine starts. Konten’s ET-1002G unmanaged switch is implemented with booster function to support 54V with 12/24VDC power input and then provide the power feeding to the other devices via its PoE features. By this way the network topology gets simpler without extra wires to reduce costs and space.

When ET-1002G is installed in bus, its Gigabit PoE Ethernet ports can smoothly link to the devices such as high resolution cameras a NVR, a PIS (Passenger Information System), monitoring screen, an alarm speaker, a wireless AP and so on. To meet the critical network environment, the industrial grade ET-1002G qualify the IP30 standard and designed with the mental housing. Its wide temperature range from -40˚C to 75˚C can ensure the Ethernet switch works durability while the bus is driving in the harsh environment.
