Dahua 16-Port Managed Switch with 2x SFP Ports

Dahua 16-Port Managed Switch with 2x SFP Ports 20-Port Managed Industrial Gigabit Switch with 16-Port PoE(Managed) Highly reliable, the L2 industrial switch is equipped with a high performance switching engine, has large buffer memory and optimizes transmission performance. With its solid full metal design, the device has great heat dissipation, working in environments ranging from –40 °C to +75 °C. It also has protection against overcurrent, overvoltage and EMC, resisting interference from static electricity, lightning and pulses. The redundant power supply ensures that the switch performs stably. It can also be remotely managed through the webpage, SNMP and more, and can directly connect to iLinks-View. PoE Watchdog Adopts the innovative PoE Watchdog. PoE Watchdog can be switched on by dialing or turning on the WEB page switch. It enables the switch to automatically detect port status and restart failed ports to recover connection in case of IPC connection exception. This enables intelligent operation and maintenance management in its truest sense, effectively reducing manual maintenance costs. Long-distance PoE By dialing or enabling long-diatance transmission on the WEB interface, the transmission distance of a PoE port can be up to 250 m, meeting the requirements of wired transmission (bandwidth reduced to 10 Mbps). Red Port 90W The red ports support IEEE802.3af, IEEE802.3at, Hi-PoE and IEEE802.3bt standards, with a maximum output power consumption rate of 90W per port. Suitable for powering high-power devices. Wide Operating Temperature Developed to operate in extreme conditions, the device functions in temperatures ranging from –40 °C to +75 °C, easily adapting to harsh environments. Redundant Power Supply Redundant power supply ensures that the device is still powered when one power port malfunctions, vastly improving device reliability. Fast Loop Convergence Supports the ERPS protocol to provide loop protection. Fast convergence is performed when the network disconnects. All-gigabit port design. Supports IEEE802.3af, IEEE802.3at, Hi-PoE and IEEE802.3bt (red port) standards. 250 m long-distance PoE transmission (10 Mbps). PoE Watchdog. Supports STP, RSTP, and ERPS. IEEE802.1Q-based VLAN configuration. Manual link aggregation and static LACP. Desktop mount and DIN-rail mount.
