Teltonika TSW101 — Automotive PoE+ Ethernet Switch 5x Gigabit for Vehicles and Fleets

Automotive Ethernet switches with PoE+ support for in-vehicle applications represent a specialized network equipment category for commercial transport, emergency vehicles, and mobile platforms where Ethernet connectivity and endpoint device power must be sourced directly from the vehicle's onboard electrical system — and the Teltonika TSW101 is purpose-built for exactly this operational profile. Providing 5 Gigabit Ethernet ports with 4 PoE+-capable ports and native 12 V or 24 V car battery operation without an additional PSU, the TSW101 is deployed in commercial vehicles, buses, trains, vessels, and mobile platforms where onboard network infrastructure must operate reliably under vibration, voltage variation, and extreme temperature conditions.

Four PoE+ ports compliant with IEEE 802.3af and 802.3at deliver up to 30 W per port with a total power budget of 60 W, supporting simultaneous powering of IP cameras, wireless access points, onboard terminals, and other active equipment installed within the vehicle. Non-blocking switching at 10 Gbps with a 128 KB packet buffer and jumbo frame support up to 9216 bytes ensures consistent performance for converged data and video traffic across the vehicle network. The 9–30 VDC input range enables direct operation from both 12 V passenger vehicle batteries and 24 V heavy commercial vehicle systems, eliminating the need for a dedicated voltage converter entirely.

TSW101 operates plug-and-play with no additional configuration required, minimizing installation complexity in vehicles where technical access is restricted and intervention time must be kept to a minimum. E-Mark certification confirms compliance with European standards for electronic equipment installed in vehicles — a mandatory requirement for homologation in commercial and public transport fleets. Profinet Class A conformance via optional order code extends applicability to industrial vehicles and mobile platforms integrated into automation systems. The aluminum enclosure with IP30 rating and verified operation across -40 °C to +75 °C ensures stable performance under the variable thermal conditions characteristic of automotive environments.

This switch is well-suited for fleet system integrators equipping commercial vehicles, buses, and trains with Ethernet infrastructure and PoE+-powered IP cameras, public transport operators deploying onboard networks for surveillance and passenger information systems, special vehicle and mobile platform manufacturers embedding E-Mark certified Ethernet connectivity into OEM solutions, and organizations in logistics and emergency services requiring a robust automotive switch with direct vehicle battery operation. The Teltonika TSW101 addresses deployments where automotive certification, PoE+ support, and PSU-free installation are simultaneous project requirements.
