The ONV-H3108PS Gigabit 10-port PoE switch is a network switch designed for use in environments where Power over Ethernet (PoE) is required. This switch typically features the following specifications:

1. Ports:

   • 8 Gigabit Ethernet PoE ports, typically capable of delivering power to devices such as IP cameras, VoIP phones, and wireless access points.
   • 2 additional Gigabit uplink ports (often non-PoE) for connecting to the broader network or other switches.

2. Power over Ethernet (PoE):

   • The PoE function allows both power and data to be transmitted through a single Ethernet cable to compatible devices. This is useful in installations where power outlets may not be readily available near the device.
   • It likely supports IEEE 802.3af/at standards for PoE, with each port typically delivering a certain wattage (e.g., 15.4W for IEEE 802.3af or up to 25.5W for IEEE 802.3at).

3. Gigabit Speeds:

   • Supports Gigabit Ethernet (1000 Mbps) for high-speed data transmission, making it suitable for modern IP-based systems and applications that require higher bandwidth, such as surveillance systems, high-definition video streaming, and data transfer.

4. Networking Features:

   • Plug-and-play setup with no need for configuration, making it user-friendly.
   • Likely to have features like auto-negotiation for speed and duplex, and auto-MDI/MDX to automatically detect cable types (straight-through or crossover).

5. VLAN Support:

   • The switch may offer VLAN (Virtual LAN) support, allowing you to segment the network for better performance and security.

6. Surge Protection and Reliability:

   • PoE switches like this one may have surge protection to safeguard against power spikes, especially important in surveillance or security systems where downtime can be costly.

The ONV-H3108PS is particularly useful in surveillance, security installations, and any scenario where devices need both power and network connectivity over a single cable.
