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 (10/100 Mbps) ports with full support for the Power over Ethernet standard. An exceptional feature of this model is that the first two ports support 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

16 x RJ45 10/100 Base-T (PoE), 2 x Combo Uplink: SFP 1000 Base-X / RJ45 10/100/1000 Base-T

A key element of the design is two Gigabit (1000 Mbps) Combo (SFP/RJ45) ports, which serve as high-speed Uplink connections. They allow for flexible connection of the switch to the rest of the infrastructure using traditional copper twisted-pair cabling or fiber optics, 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 state of connected devices and performs a hard reset if a loss of response is detected, minimizing the need for service interventions.

Additionally, the Extend mode allows for the transmission of 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 adapted for installation in 19-inch Rack cabinets, ensuring mechanical safety and optimal heat dissipation. The device features advanced surge protection up to 4kV, ensuring longevity and operational stability even in harsh environmental conditions. This is a reliable solution combining high performance with intuitive, modern administration.
