Dahua Technology PoE DH-PFS4218-16GT-240 switch de red Managed Gigabit Ethernet (10/100/1000) Power over Ethernet (PoE) negro

The Dahua Technology PFS4218-16GT-240 is a 24-port Gigabit switch tailored for high-performance network deployments. It provides 16 Gigabit Ethernet ports for wired connections, 2 SFP slots for fiber uplinks or long-distance links, and an available PoE power budget of 240W to power compatible devices. The switch implements standard layer 2 features such as VLAN, QoS, and IGMP snooping to improve traffic management and device segmentation, making it appropriate for surveillance systems and enterprise networks requiring reliable connectivity and centralized power delivery.

Advantages

The switch combines multiple connectivity options with a substantial PoE power budget, enabling simultaneous operation of cameras, access points, and other PoE devices without separate power supplies. Integrated layer 2 functions including VLAN support, QoS prioritization, and IGMP snooping help reduce broadcast traffic, prioritize critical streams, and isolate network segments. Built with a compact and robust form factor, the device fits rack or cabinet installations where stable, continuous operation is required.

Suitable for

• IP video surveillance systems requiring multiple powered cameras
• Small and medium enterprise network access layers
• Wireless access point aggregation with centralized PoE
• Remote fiber uplinks between building sites

Key specifications

• Port count: 24 total ports, including 16 Gigabit Ethernet ports and 2 SFP slots
• PoE power budget: 240W total for connected PoE devices
• Supported features: VLAN, QoS, IGMP snooping (layer 2 traffic management)
• Fiber connectivity: 2 SFP slots for fiber modules and uplinks
• Form factor: desktop or rack-mountable compact switch suitable for network cabinets

How to use

Install the switch in a suitable location with proper ventilation and secure it in a rack or place on a shelf. Connect the network backbone or router to one of the Gigabit ports or to an SFP uplink with an appropriate fiber module. Attach IP cameras, access points, or other PoE-capable devices to the Gigabit Ethernet ports to draw power from the switch within the 240W budget. Configure VLANs, QoS rules, and IGMP snooping through the switch management interface or default configuration tools to segment traffic and prioritize critical streams.

Recommendations

Monitor total PoE consumption when connecting multiple high-power devices to ensure the 240W budget is not exceeded. Use SFP fiber modules compatible with the switch for long-distance links and plan VLAN and QoS policies according to device roles to maintain predictable performance for surveillance and business-critical traffic.
