## Summary description

DAHUA DH-CS4218-16ET-190 is a managed L2 network switch with 18 Gigabit RJ-45 ports (10/100/1000) and Power over Ethernet (PoE) support. It offers a switching capacity of 7.2 Gbit/s and an 8000-entry MAC address table. Compliant with IEEE 802.3 series standards, the rack-mountable black unit suits surveillance, IP camera networks, and medium-sized LAN deployments requiring centralized management and PoE power for devices.

## Long description

The Dahua Technology DH-CS4218-16ET-190 is a Smart Managed L2 Gigabit Ethernet switch with Power over Ethernet (PoE) capabilities. It supports local management and cloud management via the DoLynk Care platform, provides topology visualization for operation and maintenance, and is built with a full metal enclosure for improved heat dissipation and dust protection. The device operates in temperatures from -10°C to 55°C and includes multiple protections against electromagnetic interference, overvoltage, overcurrent, static electricity, lightning and pulses.
Advantages
The switch supports cloud-based monitoring and real-time device status and alarm notifications through the DoLynk Care app. It offers long-distance PoE transmission up to 250 m (with bandwidth reduced to 10 Mbps), high-power PoE ports including a red BT port delivering up to 90 W per port and an orange port delivering up to 60 W, and PoE Watchdog to automatically detect and restart failed ports. LLDP-based topology discovery, link aggregation and STP (on select models) help identify issues quickly and maintain network stability.
Suitable for
Small and medium-sized businesses (supermarkets, offices)
Hospitality and food service locations (restaurants, cafés, hotels)
Security and surveillance systems requiring PoE cameras and networked devices
Rack-mounted network closets and IT rooms

How to use
Install the switch in a rack or on a stable surface and connect the AC power. Use the RJ-45 Gigabit ports to connect network devices and PoE-capable devices such as IP cameras or access points. For cloud management and real-time monitoring, register and pair the device with the DoLynk Care platform or use the web-based L2 management interface for local configuration. Enable PoE Watchdog via the web interface to allow automatic detection and restart of failed PoE ports. Configure LLDP, STP and link aggregation as needed to build the network topology and improve stability.
Usage recommendations
Place the switch in a ventilated, dust-free rack space within the specified temperature range. When using long-distance PoE (up to 250 m), expect reduced bandwidth (10 Mbps) and verify cable quality. Use the DoLynk Care app for continuous monitoring and enable PoE Watchdog and topology management to reduce manual maintenance efforts.
