Dahua CS4228-24GT-375 24-Port Gigabit PoE++ Managed Switch with 4 SFP Uplinks, 375W Budget, Layer 2, Rackmount

The Dahua CS4228-24GT-375 stands out with its high-power 375W PoE budget across all 24 Gigabit ports, supporting PoE, PoE+, and PoE++ (802.3bt) devices — ideal for demanding IP cameras, access points, and IoT endpoints. Unlike many switches that compromise on power or management, this Layer 2 managed switch delivers full enterprise features in a compact 1U rackmount form factor.

Highlights

• 24x 10/100/1000Base-T PoE ports with 375W total power budget (IEEE 802.3af/at/bt)
• 4x Gigabit SFP uplink ports for fiber connectivity
• Layer 2 managed with VLAN, QoS, Link Aggregation, and advanced security
• 56 Gbps switching capacity and 41.66 Mpps forwarding rate
• Robust design with 6kV contact / 8kV air ESD protection and 4kV lightning protection
• Smart fan with variable speed for quiet and efficient cooling
• Rack-mountable (1U) with operating temperature from -10°C to 55°C

In daily use

Deploy this switch in surveillance networks, campus access layers, or enterprise edge environments. The 375W PoE budget means you can power high-wattage devices like PTZ cameras or Wi-Fi 6 access points directly from the switch, eliminating separate power injectors. The 4 SFP uplinks provide flexible fiber connectivity to core networks. Management is straightforward via web interface, CLI, or SNMP, with support for VLANs, QoS, and security features like 802.1X and ACLs to segment and protect your network.
