## Summary description

The Dahua Technology SG4028 is a managed L2 switch featuring 26 Gigabit Ethernet ports, full duplex, and a switching capacity of 56 Gbit/s. It supports IEEE 802.1x and IEEE 802.3x standards, making it ideal for efficient network management.

## Long description

The Dahua Technology SG4028 L2 Gigabit Ethernet 26 Ports is a managed switch designed for reliable wired networks. Equipped with a high-performance switching engine, 26 Gigabit RJ‑45 ports and a total switching capacity of 56 Gbit/s, the SG4028 supports full duplex operation and common IEEE networking standards to deliver stable layer‑2 switching and efficient traffic handling in small to medium network deployments.
Advantages
The switch features low transmission delay, a large buffer and strong switching capability to optimise Ultra HD video and general data transmission. Its full metal, fanless design provides passive heat dissipation with low power consumption and quiet operation. Built‑in protections on the power input against overvoltage, EMC interference and overcurrent increase reliability in electrically noisy environments. Managed L2 functions such as Link Aggregation, QoS, LLDP, STP/RSTP and IGMP Snooping provide flexible traffic control, device discovery and loop prevention.
Suitable for
Small and medium enterprise LANs requiring managed switching
Video streaming and IP camera systems handling Ultra HD feeds
Network segments needing link redundancy and bandwidth aggregation
Environments where quiet, fanless operation is preferred

How to use
Install the SG4028 in a rack or on a flat surface and connect AC power using the supplied cable. Connect network devices to the Gigabit RJ‑45 ports; the switch auto‑negotiates 10/100/1000 Mbps and full/half duplex where supported. Access the web management interface from a connected PC to configure VLANs, Link Aggregation, QoS policies, LLDP and STP/RSTP parameters. Use IGMP Snooping to manage multicast traffic for IP video streams and review the MAC table and logs for troubleshooting.
Usage recommendations
For stable performance with multiple high‑bitrate video streams, enable Link Aggregation on uplinks to core switches and configure QoS rules prioritising video traffic. Place the unit in a ventilated area within the specified temperature range and avoid exposing power ports to moisture or strong electromagnetic interference.
