### 4. Functionality

The PCIe‑PoE2+ functions as a dual‑port Gigabit Ethernet interface card with integrated PoE power sourcing capability. It allows a host computer to connect directly to PoE‑enabled devices such as industrial cameras, sensors, or networked imaging systems without requiring separate power adapters.

Operational Principle:
- The card communicates with the host system via the PCIe x4 bus, providing high‑speed data transfer up to 1 GB/s.
- Each Ethernet port can automatically detect whether a connected device is PoE‑powered (PD) or a standard Ethernet device.
- When a PoE device is detected, the card supplies up to 15.4 W of DC power through the Ethernet cable while simultaneously transmitting data.
- The Intel® 82574L controllers manage data flow, link aggregation, and jumbo frame handling to optimize throughput and minimize latency.

Typical Use Cases:
- Machine Vision and Automated Optical Inspection (AOI):
Connects to GigE Vision cameras for high‑speed image acquisition in industrial inspection systems.
- Surveillance and Security:
Powers and connects IP cameras for monitoring and recording applications.
- Medical Imaging:
Provides reliable data transfer for diagnostic imaging devices.
- Traffic Enforcement and Intelligent Transportation Systems:
Supports high‑resolution cameras for automated license plate recognition and traffic monitoring.

Compatibility:
- Compatible with standard PCIe x4 and x16 slots (depending on motherboard configuration).
- Works with Windows XP, Vista, 7 (32‑bit and 64‑bit) operating systems.
- Supports both PoE and non‑PoE Ethernet devices.
