## Summary description

The Dahua Technology DH-CS4226-24ET-375 is a managed L2 switch with 18 Gigabit Ethernet ports, supporting Power over Ethernet (PoE) and a switching capacity of 7.2 Gbit/s. It is designed for efficient networking and can handle up to 8000 MAC addresses, making it ideal for medium to large networks.

## Long description

The Dahua Technology DH-CS4226-24ET-375 is a managed L2 Gigabit Ethernet switch with 18 RJ-45 Gigabit ports and PoE support. It provides cloud management via the DoLynk Care platform, topology visualization using LLDP, and a robust full-metal design for improved heat dissipation and reliable operation in temperatures from -10°C to 55°C. The switch includes protections for EMC, overvoltage, overcurrent, static electricity, lightning and pulse interference. Selected PoE models support long-distance power transmission up to 250 meters and offer high-power PoE ports (orange up to 60 W, red up to 90 W). Link aggregation and STP are available on specific models to maintain network stability.
Advantages
Cloud and local management combined allow real-time monitoring, alarm triggering and remote device maintenance through the DoLynk Care app. Full-metal construction delivers better thermal dissipation for continuous operation in challenging environments. Multiple protection mechanisms reduce the risk of damage from electrical disturbances. Long-distance PoE and high-power PoE ports (including BT 90W on red ports) enable powering of devices at extended distances and support high-power endpoints. PoE Watchdog and loop protection simplify fault recovery and help prevent broadcast storms.
Suitable for
 Small and medium-sized businesses (offices, supermarkets)
 Hospitality locations (hotels, cafés, restaurants)
 Security and surveillance systems requiring PoE cameras and access devices
 Network segments needing remote cloud management and topology visualization

How to use
Install the switch in a suitable rack or on a stable surface with adequate ventilation. Connect power and Ethernet cables to the appropriate RJ-45 ports. For PoE devices, use the orange or red high-power ports as required by the powered device specifications. To enable cloud management, register the switch in the DoLynk Care app and follow the app workflow to add the device for monitoring. Use the web interface or DoLynk Care to configure VLANs, link aggregation and STP settings, and to enable PoE Watchdog for automatic port recovery.
Usage recommendations
Place the switch in a ventilated area and avoid direct exposure to extreme heat or moisture. When using long-distance PoE (up to 250 m), note that bandwidth is reduced to 10 Mbps. Enable PoE Watchdog and loop protection to reduce manual maintenance and help ensure continuous operation in surveillance and critical network segments.
