The Dahua CS4220-16GT-135 is a 20-port cloud managed desktop Gigabit switch designed for larger networks that need full Gigabit connectivity, high PoE power, and centralized management in one unit. With sixteen Gigabit PoE ports and dual RJ-45 and SFP uplink options, it is built to support demanding surveillance and enterprise networking environments.
As a fully managed switch, the Dahua CS4220-16GT-135 can be configured and monitored through cloud-based platforms, including DoLynk Care and the DMSS mobile app. This gives administrators the flexibility to manage the network remotely, with real-time visibility into connected devices and PoE power status.
Power capacity is a defining strength of this switch, with a total PoE budget of 135W across sixteen Gigabit PoE ports. Ports 1 and 2 support Hi-PoE and IEEE802.3bt standards, delivering up to 90W each for high-power devices, while the remaining ports supply standard IEEE802.3af and IEEE802.3at power for typical network equipment.
Performance is another highlight of the Dahua CS4220-16GT-135, with a high switching capacity of 40 Gbps and a packet forwarding rate of 29.76 Mpps. These specifications allow the switch to handle heavy data loads with minimal latency, making it well suited for networks running multiple high-resolution video streams simultaneously.
The switch also supports VLAN configuration with up to 32 VLANs, giving network administrators the ability to segment traffic for better organization, security, and performance across different departments or device groups within a larger installation.
Built with a fully enclosed, dust-proof metal casing, the Dahua CS4220-16GT-135 is engineered to operate reliably across a wide temperature range, resisting wear in demanding environments. Its dual RJ-45 and SFP uplink combo ports add flexibility for connecting to core infrastructure over copper or fiber.
Combining full Gigabit speed, a substantial 135W PoE budget, cloud-based management, and strong network performance, the Dahua CS4220-16GT-135 is a capable solution for larger, high-demand PoE networks that require both power and centralized control.
