Product information

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

Key specifications

  • Switch type: Managed L2
  • Ports: 26 × 10/100/1000 Mbps RJ‑45 Ethernet ports
  • Switching capacity: 56 Gbit/s
  • MAC address table: 8000 entries
  • Management: Web‑based L2 management, supports LLDP, IGMP Snooping, STP/RSTP
  • Link aggregation: Manual aggregation and static LACP protocol aggregation supported
  • Power: AC supply included; input protections for overvoltage, EMC and overcurrent
  • Design: Full metal enclosure, fanless
  • Operating temperature: −10°C to 55°C
  • Weight: 1.57 kg

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.
