Dahua Technology DH-CS4226-24ET-375 netwerkswitch managed L2 Gigabit Ethernet (10/100/1000) Power over Ethernet (PoE) zwart

The Dahua Technology Managed L2 Gigabit Ethernet Switch DH-CS4226-24ET-375 is a 26-port PoE switch designed for local and cloud-enabled network management. It supports full metal construction for improved heat dissipation and operates reliably in temperatures from -10°C to 55°C. The switch provides electromagnetic compatibility and protection against overvoltage, overcurrent, static electricity, lightning and pulse interference. Select PoE models support long-distance PoE up to 250 meters, with an orange port providing up to 60 W and a red port (BT / HiPoE) providing up to 90 W. The device supports link aggregation and STP on select models and includes LLDP for topology visualization and easier operation and maintenance.

Advantages

The switch supports both local management and cloud management via the DoLynk Care platform and mobile app, enabling real-time monitoring, device status display, alarm triggering and notifications. Built-in PoE features include long-distance PoE transmission (up to 250 m at reduced bandwidth), PoE Watchdog for automatic port recovery on IPC failures, and BT 90W red ports compatible with IEEE802.3af/at/bt and HiPoE standards. Additional protections and loop prevention mechanisms reduce downtime and help maintain network stability.

Suitable for

• Small and medium-sized businesses
• Supermarkets and retail environments
• Offices and corporate networks
• Restaurants, cafés and hospitality venues
• IP camera and security system deployments

How to use

Install the switch in a suitable rack or mounting location with adequate ventilation. Connect network devices to the Gigabit RJ-45 ports and configure PoE settings as needed through the local web GUI or management interface. For cloud management, register the device in the DoLynk Care platform or app to enable remote monitoring, topology visualization and alarm notifications. Use LLDP to generate network topology maps and enable STP or link aggregation on supported models to improve resilience.

Recommendations

For deployments requiring high-power PoE devices, use the red BT/HiPoE ports (up to 90 W) and verify end-device compatibility with IEEE802.3af/at/bt or HiPoE. Enable PoE Watchdog to reduce manual maintenance by allowing automatic restart of failed PoE ports. When using long-distance PoE (up to 250 m), account for reduced bandwidth and verify that connected devices support operation at lower link speeds.
