Specifications

Dahua 16-port Managed PoE Ethernet Switch

The 16-port managed desktop switch is designed for field transmission applications and for high-definition video. The switch is equipped with a high-performance switching engine, a large buffer, low transmission delay, and high reliability. In addition to the 16 PoE ports, the switch offers two (2) gigabit uplink combo ports with a PoE budget of  240 W. The switch also delivers powerful network management functions including CLI, iLinksView, and Web and network management software based on SNMP. The switch is housed in a sealed, metal case that offers low power consumption.

Key Features:

• Layer 2 Network Management PoE Ethernet Switch 
• Intelligent PoE for Power Consumption Management 
• Long-distance PoE Transmission Distance, up to 250.0 m (820.21 ft) 
• PoE Watchdog Function Monitors Network  
• High-capacity Data Cache (4-megabit) for Real-time Transmission with smooth video 
• Supports IEEE802.3af, IEEE802.3at, Hi-PoE, and IEEE802.3bt Standards
  

Intelligent PoE

The switch features Intelligent PoE power consumption management to help keep the power and the data flowing, even when the switch experiences a power fault. Intelligent PoE monitors the power consumption of the connected devices, and in the event of large power fluctuations the switch shuts down one port at a time rather than shutting down all ports. Unlike typical switches that shut down all ports at once, this switch shuts down the highest number port first, then the next highest number until the switch detects the power consumption is below the PoE budget. For example, if the switch has eight PoE ports and each port is connected to a network camera, the switch disables port number 8 first, then subsequent ports until the power budget is below the threshold wattage.

PoE Watchdog

The switch automatically monitors each port for an active connection with the associated camera. If the switch detects a camera failure it powers off then restarts the PoE connection to restart the camera.

PoE++

The switch supports IEEE 802.3bt technology that delivers 90 W via a PoE port and drives high-power infrastructure for smart building systems, safe cities, thin clients, and many more applications. With this standard, the switch can power IT and IoT devices that demand increased power consumption resulting in lower installation and wiring costs.

Long-distance PoE Transmission

The switch extends PoE transmission distance to 250.0 m (820.21 ft), a significant improvement over typical switches. 

Environmental 

The switch is designed to operate in severe environments and in temperatures ranging from –10° C to +55° C (14° F to 131° F). The switch includes a professional-grade surge protection circuit that offers 4 kV (common mode) and 2 kV (differential mode) all-port surge protection. This protection reduces damage to the network from a lightning storm. The switch meets the Class B EMC standard and is suitable for residential, commercial, and light-industrial applications.
