The ONV-H1016PLS is a model of Gigabit uplink 18-port PoE switch. Here's an overview of its key features:

Key Features:

1. Gigabit Uplink: This switch supports high-speed data transmission with 1Gbps uplink ports, which is essential for ensuring efficient and high-performance networking in environments with large data traffic.

2. 18 Ports: It comes with 18 Ethernet ports, which are generally useful in mid-sized networks, offering flexibility to connect various network devices.

3. Power over Ethernet (PoE): It supports PoE, which allows the switch to provide both data and power to devices like IP cameras, wireless access points, or VoIP phones over a single Ethernet cable, simplifying wiring and installation.

4. PoE Power Budget: It typically has a power budget for PoE, which is crucial for supplying sufficient power to all connected PoE devices. You should check the specific power budget for this model, as it can vary.

5. VLAN and QoS Support: These switches often include features like VLAN (Virtual Local Area Network) support, enabling network segmentation and improving security. They also support QoS (Quality of Service), which helps prioritize traffic for critical applications like VoIP or video streaming.

6. Managed or Unmanaged: Depending on the model, this switch might be either a managed switch (with advanced network configuration options, monitoring, and security features) or an unmanaged switch (simpler, plug-and-play setup).

7. Reliable and Durable: These PoE switches are designed to be durable and reliable, making them suitable for continuous operation in environments that require stable network performance.

If you're considering this switch for your setup, it's important to verify the power output per port and total budget, as well as any additional features like VLAN or Layer 2/L3 functionality, depending on your network's needs.
