Description

The Dahua CS4218-16ET-135 is a professional 16-port PoE switch that serves as the foundation for modern and efficient network installations, particularly in IP video surveillance systems. The device is designed for reliability and operational continuity, offering 16 Fast Ethernet ports (10/100 Mbps) with full Power over Ethernet support. A unique feature of this model is the first two ports supporting the Hi-PoE (802.3bt) standard, capable of delivering up to 90W of power, which is critical for advanced PTZ cameras and high-power consumption devices. The remaining 14 ports operate on the 802.3af/at standard, delivering up to 30W per port, with a total power budget of 135W.

Specification

Additionally, the Extend mode allows for transmitting data and power over an impressive distance of up to 250 meters, which significantly lowers installation costs in large facilities. The entire unit is enclosed in a solid, metal housing suitable for mounting in 19-inch Rack cabinets, ensuring mechanical safety and optimal heat dissipation. The device features advanced surge protection of up to 4kV, ensuring longevity and stability even in harsh environmental conditions. This is a reliable solution combining high performance with intuitive, modern administration.

A key component of the design is the two Gigabit (1000 Mbps) Combo ports (SFP/RJ45), which act as high-speed Uplink connections. They allow for flexible connection of the switch to the rest of the infrastructure via traditional copper twisted pair or fiber optic cable, which is invaluable for long-distance data transmission. The switch offers advanced management features via a Web browser and the integrated DoLynk Care cloud, enabling full control over the network from anywhere in the world. The PoE Watchdog function automatically monitors the status of connected devices and performs a hard reset if no response is detected, minimizing the need for service interventions.
