### 4. Functionality

The PCIe-PoE354at functions as both a high-speed network interface and a power sourcing equipment (PSE) device. It transmits data and power simultaneously over standard Ethernet cables, enabling direct connection to PoE-powered devices such as GigE Vision cameras, IP cameras, and sensors.

Operational Workflow:
1. The card is installed in a PCIe x4 or compatible x16 slot on the host system.
2. Each Ethernet port automatically detects connected devices and negotiates link speed (10/100/1000 Mbps).
3. When a PoE-compatible device is detected, the card supplies power according to IEEE 802.3at standards.
4. Data transfer is managed by the Intel® I350 controller, which offloads network processing tasks from the CPU.
5. Users can control PoE power per port via Neousys API functions for remote reset or power cycling.

Use Cases:
- Machine Vision & AOI: Connect and power multiple GigE cameras for synchronized image capture.
- Surveillance & Security: Power PTZ cameras and transmit high-definition video streams.
- Medical Imaging: Provide reliable data transfer for diagnostic imaging systems.
- Traffic Enforcement: Support high-speed camera systems for automated license plate recognition.

Compatibility:
Compatible with Windows operating systems (XP, 7, 8, 8.1, 10) and standard GigE Vision-compliant devices. Supports Intel PROSet drivers and Neousys utilities.
