Product information

Description

The Dahua Technology SG4020 L2 Gigabit Ethernet Managed Switch is an 18-port, full-metal, fanless network switch designed for reliable wired networks. It offers 18 Gigabit RJ-45 ports with 10/100/1000 Mbps auto-negotiation, full-duplex support and a switching capacity of 56 Gbit/s. The switch operates in temperatures from -10°C to 55°C and includes protections for overvoltage, EMC and overcurrent on the power input to resist static, lightning and pulse interference.

Advantages

The SG4020 delivers low transmission delay, large buffers and strong switching capability to optimize delivery of high-bandwidth streams such as Ultra HD video. Its fanless, full-metal design provides effective heat dissipation and low power consumption while reducing noise and mechanical wear. Managed L2 features and web-based management enable centralized configuration and troubleshooting, and hardware protections improve reliability in industrial or demanding environments.

Suitable for

  • Small and medium business wired networks
  • Surveillance systems and Ultra HD video distribution
  • Edge and branch office network aggregation
  • Environments requiring quiet, fanless operation

  • Console port: RJ-45
  • Switching capacity: 56 Gbit/s
  • MAC address table: 8000 entries
  • Management: Web-based L2 management, LLDP, STP/RSTP, IGMP Snooping
  • Features: Link Aggregation (manual and static LACP), QoS
  • Form factor: 1U rack-mountable
  • Power: DC power supply included; input protections for overvoltage, EMC and overcurrent
  • Operating temperature: -10°C to 55°C
  • Colour: Black
  • Weight: 1.57 kg

How to use

Install the SG4020 in a standard 1U rack or place it on a flat surface. Connect each network device to the Gigabit RJ-45 ports using Cat5e or better cabling. Use the console or web-based interface to configure VLANs, Link Aggregation, QoS policies, STP/RSTP and IGMP Snooping according to network requirements. Ensure the DC power supply is connected to a properly rated source and verify grounding to maintain protection against electrical interference.

Usage recommendations

For optimal performance when distributing Ultra HD video or large multicast streams, enable IGMP Snooping and configure QoS and Link Aggregation where multiple uplinks exist. Use Cat6 cabling for future-proofing and ensure regular firmware updates via the vendor to maintain security and stability.
