Unmanaged Gigabit Ethernet Switch DAHUA PFS4218-16ET-240, 16x RJ-45 PoE ports, 8.8 Gbit/s, MAC 4000

The Dahua Technology PFS4218-16ET-240 is an unmanaged Gigabit Ethernet switch with 16 RJ-45 ports supporting PoE. It provides a switching capacity of 8.8 Gbps, a forwarding rate of 5.36 Mpps and a MAC address table sized for 4000 entries. Compliant with relevant IEEE Ethernet and PoE standards, the switch is designed to deliver simultaneous power and data to connected devices in small to medium surveillance and network environments.

Advantages

This unmanaged Dahua switch supports PoE according to multiple IEEE standards and offers a 90 W PoE power budget for powering cameras and other PoE devices. With Gigabit Ethernet ports and an 8.8 Gbps switching capacity, it ensures full-duplex data throughput for connected devices. The compact 440 × 300 × 44 mm metal form factor and a net weight of 3.32 kg make it suitable for rack or shelf installation in equipment rooms.

Suitable for

• IP surveillance camera deployments requiring PoE power
• Small to medium office or retail network expansion
• Edge switch use in distributed network topologies

How to use

Install the switch on a flat surface or in a suitable rack space and connect each network device using Cat5e or better Ethernet cables. Connect PoE devices directly to the RJ-45 PoE ports; the switch will supply power automatically according to the connected device and supported PoE standard. Connect the switch uplink to your router or core switch to provide network connectivity to all ports. Ensure adequate ventilation around the unit and follow local electrical installation rules when integrating into a powered network.

Recommendations

For deployment with multiple high-power PoE devices, verify cumulative power consumption to ensure it does not exceed the 90 W PoE budget; distribute high-draw devices across separate switches or use a higher-budget PoE source when necessary.
