Network Switch DAHUA S4100-8ET2GT-96-C — 8x 10/100/1000 Mbps Ethernet Ports

DAHUA S4100-8ET2GT-96-C is a compact smart managed Layer-2 network switch with eight 10/100 Mbps Ethernet ports and two 10/100/1000 Mbps uplink ports. Designed for small to medium deployments, the switch supports long-distance PoE transmission up to 250 m (with bandwidth reduced to 10 Mbps at extended distances) and a high-power red PoE port capable of delivering up to 90 W for powering high-consumption devices. The device integrates cloud management via the DoLynk Care app, automatic network topology generation using LLDP, visualized maintenance and PoE watchdog functionality for remote monitoring and faster troubleshooting.

Advantages

The switch combines long-distance PoE capability and multi-standard PoE support (IEEE 802.3af/at/bt and Hi-PoE) to supply power and network connectivity to cameras, access points and other IP devices without separate power sources. Cloud management through the DoLynk Care app reduces on-site maintenance effort by offering topology visualization and remote control. Built-in PoE watchdog and power management policies help detect and recover failed ports automatically, lowering manual intervention and improving uptime. Compact dimensions and standard Ethernet/CAT5e–CAT6 compatibility simplify installation in offices, retail sites and small industrial locations.

Suitable for

• IP surveillance systems with PoE cameras requiring long cable runs or high-power ports
• Small and medium office networks needing reliable Gigabit uplinks and visual network management
• Retail and branch sites deploying access points, POS terminals and IoT devices
• Factory floor or building segments where extended PoE transmission is required

How to use

Install the switch on a flat surface or in a compact mounting location and connect the included 53 VDC power adapter. Use CAT5e or CAT6 cables to connect PoE devices to ports 1–8 and uplink switches or routers to the two Gigabit uplink ports. Configure and manage the device remotely using the DoLynk Care mobile app to view automatically generated network topology, monitor port and PoE status, and apply power management policies. When using long-distance PoE, verify the required bandwidth and power capacity for each device because extended cable lengths reduce available bandwidth and load capacity.

Usage recommendations

For reliable operation, use quality CAT5e/CAT6 cables with DC resistance below 10 ohm/100 m, and place high-power devices on the red PoE port when they require up to 90 W. For camera or device placements beyond 100 m, plan for reduced bandwidth (10 Mbps at extended ranges) and confirm device power draw to ensure sufficient load capacity at 150–250 m. Use the DoLynk Care app for topology checks and enable PoE watchdog features to minimize downtime and simplify remote maintenance.
