Fortinet 1-Port Gigabit PoE Power Injector GPI-115, 802.3af 15.4W, 10/100/1000 Mbps, 50V

Fortinet GPI-115 is a single-port Gigabit Power over Ethernet (PoE) injector that adds 802.3af PoE power to a standard Ethernet link. It delivers up to 15.4 W at 50 V over a 10/100/1000Base-T connection and is intended to power devices such as wireless access points and other 802.3af-compatible equipment while passing Gigabit Ethernet data rates over standard cabling.

Advantages

The GPI-115 provides a compact mid-span PoE solution that converts a non-PoE port into a powered Ethernet connection without changing existing switches. It supports Gigabit data rates, uses an auto-sensing algorithm to detect 802.3af-powered devices, and accepts a wide AC input range for worldwide mains compatibility. The unit is certified to common safety and emissions standards.

Suitable for

• Powering 802.3af-compliant wireless access points (including FortiAP models)
• Adding PoE capability to non-PoE switches or wall ports
• Supplying power to IP phones, cameras, or other low-power network devices that require up to 15.4 W

When it may not be suitable

The GPI-115 supplies up to 15.4 W (802.3af) and therefore is not suitable for devices that require higher PoE power levels such as 802.3at (PoE+) or newer high-power devices. It is a single-port mid-span injector, so it will not replace a multi-port PoE switch when powering multiple devices from one unit is required.

Key specifications

• PoE standard: IEEE 802.3af (up to 15.4 W)
• Output voltage: 50 V
• Data rate: 10/100/1000 Mbps (Gigabit Ethernet)
• Ports: 2 Ethernet (RJ-45) ports — data+power out and data in
• AC input: universal 90–264 V AC
• Weight: approximately 0.2 kg
• Compliance: CE, FCC, RoHS, WEEE, UL/CUL

How to use

Connect the injector's data input RJ-45 port to a non-PoE switch or Ethernet port using standard Cat5e/Cat6 cable. Plug the powered RJ-45 output into the 802.3af-compatible device to deliver both data and power. Connect the injector to AC mains using the included power cord and ensure the device being powered supports IEEE 802.3af. The injector automatically detects compliant powered devices and supplies PoE without manual configuration.

What to consider before purchase

• Verify the powered device supports IEEE 802.3af and requires no more than 15.4 W.
• Confirm a single-port injector meets your deployment needs; multiple devices require multiple injectors or a PoE switch.
• Ensure cable quality (Cat5e or better) to support Gigabit speeds and reliable PoE delivery.

Usage recommendations

The injector is best used as a compact solution to add PoE to individual non-PoE ports, for example to power a single FortiAP access point or similar 802.3af device. For installations with several devices, consider a multi-port PoE switch to simplify management and reduce cabling.
