## Summary description

DAHUA S3228-24GT-375 is an unmanaged L2 network switch with 26 Gigabit RJ-45 ports (including 24 PoE-capable ports) and 2 SFP slots for fiber uplinks. It supports IEEE 802.3 standards including 802.3af/at/bt for PoE, an 8000-entry MAC table and 52 Gbit/s switching capacity. Suitable for powering IP cameras, access points and small-to-medium LAN aggregation in rack installations.

## Long description

DAHUA S3228-24GT-375 is an unmanaged L2 PoE network switch with 26 Gigabit Ethernet ports (24 PoE-capable) and 2 SFP uplink slots. It combines a high-performance switching engine and a large cache to ensure stable transmission of video streams and other network traffic. The device supports long-distance PoE, PoE Watchdog, VIP ports and port isolation for improved reliability and security. The designated red port supports IEEE 802.3bt and Hi-PoE and can supply up to 90 W to power high-consumption devices. The switch operates reliably in temperatures from −10 °C to 55 °C and includes EMC compliance and protections against overvoltage, overcurrent, static discharge, lightning and pulse interference.
Advantages
The switch provides 24 PoE Gigabit ports alongside two Gigabit uplink ports and two SFP uplinks, delivering a 52 Gbit/s switching capacity and an 8000-entry MAC address table for efficient layer-2 forwarding. Long-distance PoE extends transmission up to 250 m with bandwidth adjusted to 10 Mbps for extended reach, while PoE Watchdog monitors port status and automatically reboots faulty devices to reduce manual maintenance. Port isolation prevents connected devices from communicating directly, reducing data leakage risk and isolating broadcast storms without VLAN configuration. The red PoE port supports multiple PoE standards including IEEE 802.3bt and Hi-PoE with up to 90 W output for powering high-demand equipment.
Suitable for
Powering IP cameras and managing video streams in small to medium surveillance systems
Supplying PoE to access points and VoIP phones in offices or branch sites
Rack-mounted aggregation in small-to-medium LANs for factories, offices and residential deployments
When it may not be suitable
This is an unmanaged L2 switch, so it does not provide advanced managed features such as VLAN configuration via a management interface, SNMP-based monitoring or dynamic routing. Environments that require fine-grained traffic control, complex QoS policies, or centralized VLAN management may require a managed switch instead.
Key specifications
Ports: 24 × RJ-45 Gigabit PoE ports, 2 × RJ-45 Gigabit uplink ports, 2 × SFP 1 Gbps uplink ports (total 26 RJ-45 switching ports)

PoE standards supported: IEEE 802.3af, IEEE 802.3at, IEEE 802.3bt, Hi-PoE
Red port PoE output: up to 90 W
Long-distance PoE: up to 250 m (bandwidth adjusted to 10 Mbps)
PoE Watchdog: automatic port status detection and reboot
Port isolation and VIP port support (priority for ports 1–8)
Operating temperature: −10 °C to 55 °C
Form factor: rack-mountable; color: black; weight: 2.66 kg
How to use
Install the switch in a standard rack or place it on a stable surface, connect uplink ports or SFP modules to the network backbone and connect PoE devices (cameras, access points, phones) to the PoE RJ-45 ports. The device is unmanaged so it begins forwarding traffic once powered and connected. Use the VIP ports to prioritize traffic for critical PoE devices and enable long-distance PoE connections by connecting compatible devices up to 250 m away (expect reduced bandwidth to 10 Mbps for extended runs). Rely on PoE Watchdog to automatically detect and restart ports with connection exceptions.
What to consider before purchase
If you need SNMP, VLAN management or advanced QoS, choose a managed switch instead of this unmanaged model
Verify connected devices support reduced 10 Mbps links when using long-distance PoE to 250 m
Check total PoE power budget of your installation and power requirements of connected devices, especially if multiple high-watt devices will be powered
Ensure rack space and ventilation meet the operating temperature and installation requirements
Usage recommendations
For stable surveillance and access point deployments, connect critical cameras or APs to the designated VIP ports and use the red IEEE 802.3bt/Hi-PoE port for single high-power devices. Plan cable runs and total power budget before installation to ensure reliable long-term operation.
