## Long description

Dahua CS4220-16GT-240 is a managed L2 Gigabit PoE switch with 18 Gigabit RJ-45 ports that support 10/100/1000 Mbps and Power over Ethernet. The switch provides a MAC address table of 8,000 entries and a switching capacity of 40 Gbit/s. It supports common IEEE 802.3 standards and PoE power supply modes including IEEE 802.3at/bt and Hi-PoE, is rack-mountable and has a full-metal enclosure designed for durable operation in small and medium-sized business networks.
Advantages
The switch supports both local Web-based managed L2 features and cloud management via the DoLynk Care platform, with topology visualization and centralized maintenance for security and IT devices. Its full-metal chassis offers improved heat dissipation and dust protection, enabling operation from -10°C to 55°C. PoE models can provide extended power delivery up to 250 m; specific high-power ports deliver up to 60 W (orange) or 90 W (red). The device includes EMC protection and safeguards against overvoltage, overcurrent, static, lightning and pulse interference, while selected models offer link aggregation and STP for network stability.

How to use
Install the Dahua CS4220-16GT-240 in a standard 19-inch rack or place it on a flat surface with adequate ventilation. Connect uplink and client devices to the Gigabit RJ-45 ports using Cat5e/Cat6 cables. For PoE devices, enable PoE per-port settings through the Web management interface or the DoLynk Care cloud platform, and configure power limits if required. Use the switch’s management interface to set VLANs, link aggregation, STP and other L2 features, and verify topology visualization for device and link status.
Usage recommendations
For reliable PoE delivery, use suitable cables (Cat5e or higher), verify total PoE budget against connected devices, and segregate high-power devices on designated high-power ports. Keep firmware updated via the vendor interface and place the switch in a ventilated rack space to maintain operating temperature and reduce interference risk.
