1. Introduction
The TRENDnet TI-IG90 is a robust, industrial-grade Gigabit 4PPoE injector designed for demanding environments. It provides Power over Ethernet (PoE) capabilities to network devices, delivering up to 90W of power over a single Ethernet cable. This unit is built with hardened components and features an IP30-rated metal enclosure, ensuring reliable operation in extreme temperatures and harsh industrial settings. It supports PoE, PoE+, and 4PPoE standards, making it versatile for various power requirements. The TI-IG90 also includes redundant power inputs for enhanced reliability and comes with both DIN-Rail and wall mount hardware for flexible installation.

4. Setup and Installation
4.1 Mounting the Injector
The TI-IG90 can be mounted on a DIN-rail or directly to a wall using the provided brackets.
- DIN-Rail Mount: Attach the DIN-rail clip to the back of the injector. Align the clip with the DIN-rail and push the injector firmly until it clicks into place.
- Wall Mount: Secure the wall mount brackets to the desired surface using appropriate screws (not included). Then, attach the injector to the brackets.

4.2 Connecting the Injector
- Connect Data Input: Connect an Ethernet cable from your non-PoE Gigabit switch or network device to the DATA port on the TI-IG90.
- Connect PoE Output: Connect an Ethernet cable from the PoE port on the TI-IG90 to your PoE-compatible device (e.g., IP camera, wireless access point).
- Connect Power: Connect a compatible industrial power supply (e.g., TRENDnet models TI-S15052, TI-S12048, sold separately) to the removable terminal block on the top of the injector. Ensure correct polarity. The TI-IG90 supports redundant power inputs for increased reliability.

This image provides a top-down view of the TRENDnet TI-IG90 90W 4PPoE Injector, clearly showing the two Ethernet ports labeled 'POWER' (PoE output) and 'DATA' (data input). The LED indicators for PW1, PW2, and PoE status are also visible, along with the TRENDnet branding.
4.3 Power On
Once all connections are secure, apply power to the industrial power supply. The Power LEDs (PW1/PW2) on the injector should illuminate, indicating successful power-up. The PoE LED will illuminate when a PoE device is connected and receiving power.
5. Operating the Injector
The TRENDnet TI-IG90 operates automatically once properly connected and powered. It functions as an intermediary device, injecting power into the Ethernet cable to power connected PoE devices while simultaneously transmitting data. No configuration is required for basic operation.
- Power LEDs (PW1, PW2): Indicate that power is being supplied to the injector from the respective power inputs.
- PoE LED: Illuminates when a PoE device is detected and actively receiving power from the injector.
6. Maintenance
The TI-IG90 is designed for minimal maintenance. However, regular checks can ensure optimal performance:
- Keep the unit clean and free from dust and debris.
- Ensure proper ventilation around the unit, especially in enclosed spaces.
- Periodically check all cable connections for secure fit.
- Verify LED indicators are functioning as expected.
7. Troubleshooting
7.1 No Power to Injector
- Ensure the power supply is correctly connected to the terminal block and is providing the correct voltage.
- Check the power source (outlet, power strip) for functionality.
- Verify the terminal block connections are secure and correctly wired.
7.2 No Power to PoE Device
- Confirm the PoE device is compatible with PoE, PoE+, or PoE++ standards.
- Check the Ethernet cable connecting the injector's PoE port to the device. Ensure it is a standard Ethernet cable (Cat5e or higher) and is not damaged.
- Verify the PoE LED on the injector is illuminated. If not, the injector may not be detecting the PoE device or providing power.
- Ensure the total power consumption of the PoE device does not exceed the injector's maximum output (90W).
7.3 No Data Connection
- Check the Ethernet cable connecting the non-PoE switch/router to the injector's DATA port.
- Verify the Ethernet cable connecting the injector's PoE port to the device.
- Ensure the connected network devices (switch, PoE device) are functioning correctly.
