4. Functionality
The PET-102GT++ functions as a PoE power injector that bridges standard Ethernet data with power delivery over the same cable. It can receive power through its PD port from an upstream PoE switch or injector and then distribute power to downstream devices through its two PSE ports.

Operational Modes:
- PD Mode: Receives power from an upstream PoE source (e.g., PoE switch or midspan injector) via the PD port.
- PSE Mode: Supplies power to connected PoE devices (e.g., IP cameras, access points) through the two PSE ports.

Use Cases and Applications:
- Industrial automation systems requiring distributed PoE power delivery.
- Surveillance networks powering multiple IP cameras from a single PoE uplink.
- Wireless infrastructure deployments (Wi-Fi access points, point-to-point radios).
- Smart building systems integrating sensors, controllers, and IP-based devices.
- Transportation and utility monitoring systems where compact, rugged PoE injectors are needed.

Compatibility:
- Compatible with IEEE 802.3af (PoE) and IEEE 802.3at (PoE+) devices.
- Works with standard Ethernet switches, routers, and network controllers.
- Supports auto-detection of PoE devices to prevent damage to non-PoE equipment.
