DS-3T0510HP-E-HS 8 Port Gigabit Unmanaged Harsh POE Switch: This robust POE switch features 6 gigabit PoE RJ45 ports, 2 gigabit Hi-PoE RJ45 ports, and 2 gigabit SFP fiber optical ports. It adheres to IEEE 802.3at/af/bt standards with a maximum of 90 W PoE output for Hi-PoE ports and 30 W for standard PoE ports. It supports IEEE 802.3, IEEE 802.3u, IEEE 802.3x, IEEE 802.3z, and IEEE 802.3ab standards. The switch includes 6 kV surge protection, supports up to 300 m long-range transmission, and features a PoE watchdog for auto-restarting non-responsive cameras. Designed for harsh environments, it operates in temperatures ranging from -30 °C to 65 °C and includes port isolation for enhanced network security. The switch is built with a solid high-strength metal shell and reliable fan-free design.
