DS-3E1552P-SI - 48 Port Gigabit Smart POE Switch

The Hikvision DS-3E1552P-SI is an enterprise-grade, high-density 48-port Gigabit Smart managed PoE (Power over Ethernet) network switch engineered for massive data throughput, advanced Layer 2 security, and intelligent power optimization in large-scale IP surveillance infrastructure. Built inside a robust metal chassis equipped with 6 kV surge protection, this switch features forty-eight dedicated 10/100/1000M Gigabit PoE ports, two standard Gigabit RJ45 uplink ports, and two Gigabit SFP fiber optical uplink ports for long-distance network backhaul, all backed by a massive 470-watt total PoE power budget. The device integrates advanced management and cybersecurity defenses, including IEEE 802.1Q VLAN tagging for secure traffic segmentation, SNMP for network monitoring, Quality of Service (QoS) for video traffic prioritization, DHCP snooping, and ARP anti-spoofing to block unauthorized rogue access. For maximum network reliability, it supports STP/RSTP/ERPS loop prevention with integrated storm control and incorporates intelligent power-saving technologies with user-configurable plans compliant with Energy Efficient Ethernet standards.
