DS-3E0520HP-E switches are layer 2 Hi-PoE switches, providing advanced PoE power supply technology and Gigabit networks design on the basis of highperformance access to ensure stable data upload. The switches support Hi-PoE, long range, port isolation, and PoE watchdog function.

• 12 × gigabit PoE ports, 4 × gigabit Hi-PoE ports, 2 × gigabit RJ45 ports, and 2 × gigabit fiber optical ports.
• IEEE 802.3at/af/bt standard for Hi-PoE ports (Max. 90 W PoE output).
• IEEE 802.3at/af standard for PoE ports (Max. 30 W PoE output).
• IEEE 802.3, IEEE 802.3u, IEEE 802.3x, IEEE 802.3ab, and IEEE 802.3z standard.
• 6 KV surge protection for PoE ports.
• Up to 300 m long-range transmission.
• PoE watchdog to auto detect and restart the cameras that do not respond.
• Port isolation to improve network security.
• Gigabit network access design.
• Wire-speed forwarding.
• Store-and-forward switching.
• Solid high-strength metal shell.
