The Teltonika TSW101 is designed specifically for the automotive industry, featuring five Basic Switching RJ-45 Ethernet ports that support Gigabit Ethernet (10/100/1000). This automotive PoE+ switch enables the connection and powering of multiple devices through the same interfaces, facilitating high bandwidth connectivity. It includes a MAC address table capable of holding 2000 entries and boasts a switching capacity of 10 Gbit/s. Adhering to networking standards such as IEEE 802.3, IEEE 802.3az, and IEEE 802.3u, the switch ensures compatibility and efficient energy usage. The power is supplied via a terminal block (2-pin) connector, simplifying the installation process. The integration of Power over Ethernet (PoE) technology allows for the transfer of electrical power, along with data, to devices over the network cables, reducing the need for additional power supplies. This switch is an effective solution for enhancing network performance and simplifying device management in automotive environments.
