### 4. Functionality

The GPI8000 functions as a mid-span PoE injector, enabling network administrators to add PoE capability to existing Ethernet infrastructure without replacing non-PoE switches. It injects DC power into the Ethernet cable while maintaining full data throughput, allowing connected devices such as IP cameras, VoIP phones, wireless access points, and network sensors to receive both power and data over a single cable.

Operational Principle:
- Data Input: The injector receives Ethernet data from a standard switch or router via the “Data In” RJ45 ports.
- Power Injection: The internal power supply converts AC input to the appropriate DC voltage and injects it into the Ethernet pairs according to IEEE 802.3af specifications.
- Data + Power Output: The “Data Out” RJ45 ports deliver combined data and power to PoE-compatible devices.
- Detection & Classification: The GPI8000 automatically detects whether a connected device supports PoE and classifies its power requirements before enabling power delivery.
- Protection: Built-in overload and short-circuit protection prevent damage to both the injector and connected devices.

Use Cases and Applications:
- Expanding PoE capability in existing non-PoE networks.
- Powering IP surveillance cameras, VoIP phones, wireless access points, and network sensors.
- Deploying remote network devices where separate power outlets are unavailable.
- Integrating with RAYON’s PoE splitters (SP1301, SP2401) to power non-PoE devices.
- Supporting industrial, commercial, and enterprise network environments.

Compatibility:
- Compatible with IEEE 802.3af-compliant powered devices (PDs).
- Supports Cisco legacy PoE detection for older Cisco equipment.
- Works with standard Cat5e/Cat6 Ethernet cabling up to 100 meters.
