Description
Long Description
The DH-PFS3226-24ET-240 is a Layer 2 unmanaged PoE switch designed to provide network connectivity and centralized power distribution for IP cameras and other PoE devices. It features 24 RJ45 10/100 Mbps PoE ports, allowing compatible cameras to receive both data and power through a single Ethernet cable.
The switch provides a 240W total PoE budget. Ports 1–2 can deliver up to 60W per port, while ports 3–24 support up to 30W per port, making the switch suitable for standard IP cameras as well as higher-power devices such as PTZ cameras. It supports IEEE 802.3af, IEEE 802.3at and Hi-PoE standards.
For network expansion, ports 25–26 are combo uplink interfaces, providing 10/100/1000 Mbps RJ45 connectivity or 1000 Mbps SFP connectivity. The switch also supports long-distance PoE transmission up to 250 metres under supported conditions.
The PoE Watchdog (PD Alive) function can monitor connected powered devices and automatically restart a device when communication or power status indicates a problem. Port isolation and QoS functions are also available through the switch’s functional controls.
