The ONV-H3016PS Gigabit 18-port PoE Switch is a network switch designed to deliver both high-speed data and Power over Ethernet (PoE) for connected devices. Here's an overview of its key features:

Key Features:

1. 18 Ports: This switch provides 18 Ethernet ports, which are usually a combination of regular data ports and PoE-enabled ports.

2. Gigabit Speed: All ports are typically Gigabit (10/100/1000 Mbps), ensuring high-speed data transfer for networking needs.

3. Power over Ethernet (PoE): It can deliver power and data through a single Ethernet cable to connected devices such as IP cameras, wireless access points, VoIP phones, and other PoE-enabled devices.

4. PoE Budget: PoE switches usually have a specified maximum PoE power budget, which is the total amount of power it can provide across all the connected devices. The ONV-H3016PS should have a certain PoE wattage capacity, such as 250W or more, depending on the model.

5. VLAN Support: It may support Virtual LAN (VLAN) for network segmentation and better traffic management.

6. Plug-and-Play: Most PoE switches, including this model, offer plug-and-play installation without the need for additional configuration.

7. Rack-Mountable: It could be designed for mounting in a standard 19-inch network rack for organized setup.

Typical Use Case:

• IP Surveillance Systems: As this is a PoE switch, it's commonly used to power IP cameras in security systems.
• Wireless Access Points (WAPs): It can provide both data connectivity and power for WAPs in an enterprise or large office setting.
• VoIP Phones: Providing both data and power to VoIP phones in a corporate environment.

For further specifications like PoE power budget or features like QoS, checking the datasheet or manual from the manufacturer (ONV) would provide more details specific to your model.
