Dahua Technology PoE DH-PFS3220-16GT-190 network switch Unmanaged L2 Gigabit Ethernet (10/100/1000) Power over Ethernet (PoE) 1U Black

DH-PFS3220-16GT-190 is an unmanaged L2 PoE switch from Dahua Technology that provides 18 Gigabit Ethernet ports in a 1U rack-mountable form factor. The device supports IEEE 802.3bt PoE standard with a maximum single-device power output of up to 90 W and includes a power consumption management strategy to maintain stable operation under heavy load. Gigabit copper ports deliver high-definition network access while the gigabit uplink fiber option enables long-distance transmission.

Advantages

The switch implements IEEE802.3bt PoE for higher power delivery to connected devices and a power management strategy to prevent overloads. Unmanaged operation requires no configuration, simplifying deployment. Gigabit ports ensure high throughput for HD video and data, and the availability of fiber uplink supports long-distance, low-latency connections. The compact 1U design suits server racks and network closets.

Suitable for

• IP camera systems and video surveillance requiring PoE
• Small to medium business networks needing straightforward Gigabit switching
• Network closets and server rooms with rack-mounted equipment
• Connections requiring long-distance uplink via fiber

How to use

Install the switch in a 1U rack space or place it on a stable surface. Connect Ethernet devices to the Gigabit RJ-45 ports for data and PoE power delivery; use the designated uplink fiber port for long-distance connections to switches or network equipment. Ensure connected PoE devices are compatible with IEEE 802.3bt and do not exceed the total available power budget. No configuration is required for basic operation; power on the device and verify link/activity LEDs to confirm connectivity.

Recommendations

Place the switch in a ventilated, dust-free environment and ensure the rack or shelf supports the 1U dimensions and weight. Plan PoE load distribution to avoid exceeding the overall power budget, and use quality fiber and copper cabling for reliable long-distance and high-speed links.
