### 4. Functionality

The GPI8001 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 terminals to receive both power and data over a single cable.

Operational Principle:
- Data Input: The injector receives data signals from a non-PoE switch or router via the “Data In” RJ45 ports.
- Power Injection: The GPI8001 adds 48VDC power to the Ethernet lines according to IEEE 802.3af/at standards.
- Data + Power Output: The combined data and power are transmitted through the “Data Out” RJ45 ports to PoE-enabled devices.
- Power Management: The internal controller monitors each port’s load, dynamically allocating power and protecting against overload or short-circuit conditions.
- LED Monitoring: Front-panel LEDs indicate operational status, simplifying troubleshooting and network monitoring.

Use Cases and Applications:
- Expanding PoE capability in existing non-PoE networks.
- Powering IP surveillance cameras, wireless access points, VoIP phones, and network sensors.
- Industrial automation systems requiring centralized power distribution.
- Remote installations where AC power outlets are limited.
- Integration with RAYON’s PoE splitters (SP1301, SP2401) and PD modules (PD1301, PD2401) for mixed PoE/non-PoE environments.

Compatibility:
- Compatible with IEEE 802.3af-compliant powered devices.
- Backward-compatible with Cisco legacy PoE devices.
- Works with standard Cat5e/Cat6 Ethernet cabling up to 100 meters.
