Kyland's Aquam series offers a range of ruggedized, EN50155-certified Ethernet switches tailored for rail and transportation. With IP65 protection, aluminum casings, and high vibration/shock resistance, these switches include managed models with rail-specific features like TTDP, R-NAT, and redundancy protocols, as well as unmanaged variants. Highlights are high port density up to 24+4G, gigabit bypass, PoE/PoE+ support, and a configuration backup tool - making the Aquam series ideal for harsh rail environments.
