4. Functionality
The GPI1001 functions as a midspan PoE injector, combining power and data onto a single Ethernet cable to supply remote devices such as IP cameras, VoIP phones, wireless access points, and network sensors. It connects between a non-PoE switch (data source) and a PoE-capable device (PD). The injector receives data from the switch through the “Data In” RJ45 port and outputs both data and DC power through the “PSE Data Out” RJ45 port.

Use Cases and Applications:
- IP Surveillance Systems: Powering IP cameras in remote or outdoor locations without local power outlets.
- Wireless Networking: Supplying power to wireless access points or bridges in enterprise or industrial environments.
- VoIP Telephony: Enabling PoE for IP phones in office networks.
- IoT and Automation: Powering sensors, controllers, and embedded devices in smart building or industrial automation systems.
- Network Upgrades: Adding PoE capability to existing non-PoE switches without infrastructure replacement.

Compatibility:
- Compatible with IEEE 802.3af and 802.3at compliant powered devices.
- Supports both “Power over Data Lines” and “Power over Spare Lines” architectures depending on network configuration.
- Backward compatible with Cisco legacy PoE detection protocols.
