With a total power budget of up to 160W, this injector enables flexible, scalable installations for IP cameras, high-performance wireless access points, VoIP phones, POS terminals, and other PoE-enabled endpoints. The device handles longer runs up to 100 meters (328 feet) per link, enabling remote mounting for cameras and access points while simplifying cable management and reducing infrastructure costs. Designed for plug-and-play operation, it integrates smoothly into any network topology, delivering reliable power and speed without complex configuration.

• High-speed multi-gigabit power delivery: Four independent PoE++ ports deliver data and power across a wide range of devices at speeds up to 5Gbps, 2.5Gbps, and 1Gbps on each link. This enables high-bandwidth applications such as 4K video surveillance, high-performance wireless access points, and fast, responsive IP devices, all powered through standard Ethernet cabling. The injector continuously negotiates with each connected device to provide the appropriate level of power while maintaining stable data transmission, so you can deploy powerful devices without sacrificing network performance.
• Support for PoE ecosystems (802.3af/at/bt): The injector supports PoE (802.3af), PoE+ (802.3at), and PoE++ (802.3bt), offering a flexible power solution for a wide range of devices. With a total power budget of up to 160W, you can power multiple high-demand devices simultaneously while ensuring reliable operation even on longer cable runs. This broad standard support makes it an excellent fit for mixed-device environments where older PoE devices coexist with newer, power-hungry equipment.
• NBASE-T capability for future-proof deployments: Leveraging NBASE-T technology, the device delivers multi-gig speeds over existing Cat5e/Cat6 cabling, enabling 5Gbps and 2.5Gbps performance where supported by the connected devices. This opens up opportunities for upgrading backhaul bandwidth and improving client experiences without rewiring, while maintaining compatibility with legacy ethernet devices at 1Gbps or lower when required.
• Long reach with reliable data+power delivery: The injector supports remote powering over distances up to 100 meters (328 feet) per link when used with compliant cabling, enabling strategic placement of PoE-powered devices far from the network core. This feature is ideal for outdoor or campus environments, remote surveillance locations, and backstage installations where access to power is limited, allowing you to position devices exactly where they’re needed without compromising performance.
• Plug-and-play simplicity and robust design: Designed for straightforward deployment, this injector requires no complex setup or driver installation. Simply connect to a compatible power source, link the input to your network, and attach PoE-enabled devices to the four output ports. Its compact, durable build is well-suited for IT closets, back rooms, retail floors, and industrial settings where reliable, maintenance-free operation is essential.

How to Install StarTech.com 4-Port Multi-Gigabit PoE++ Injector

• Step 1: Connect the injector to a suitable power source using a compatible external power adapter. Ensure the unit is powered on and placed in a ventilated area to maintain optimal performance and longevity.
• Step 2: Link your network to the injector by connecting the network switch or router to the injector’s input port with a standard Ethernet cable. This establishes the data path for all four downstream ports.
• Step 3: Attach PoE-enabled devices to the four output ports using Cat5e or Cat6 Ethernet cabling. Ensure the total power draw of connected devices does not exceed the 160W budget to maintain stable operation.
• Step 4: Verify device operation by checking that powered devices initialize correctly and that data connectivity is established. If devices fail to power, recheck cable quality and ensure devices are PoE-capable and enabled.
• Step 5: If required, adjust device placement to optimize performance (e.g., reduce cable length where possible to minimize potential signal loss) and perform any device-specific configuration per manufacturer recommendations. The injector is designed for immediate plug-and-play use in most scenarios.

Frequently asked questions

• Q: What is PoE++ and which devices benefit most?

  A: PoE++ refers to the 802.3bt standard that provides higher power delivery over Ethernet. It is especially beneficial for power-hungry devices like multi-radio wireless access points, high-powered IP cameras, advanced LED lighting, and other equipment that requires more than PoE or PoE+ can supply. The StarTech injector supports PoE++, PoE+, and PoE, enabling a wide range of devices to be powered from a single, centralized source.

• Q: Can I mix PoE standards on different ports?

  A: Yes. The injector supports multiple PoE standards (802.3af, 802.3at, and 802.3bt) across its ports. This allows you to power a mix of devices with varying power needs as long as the total budget remains within 160W.

• Q: How far can I place powered devices from the injector?

  A: Each link can deliver data and power over copper cabling up to 100 meters (328 feet), assuming proper Cat5e/6 cabling and device requirements. Distances may vary slightly based on cable quality and environmental factors.

• Q: Do I need special software to use this injector?

  A: No. The injector is designed for plug-and-play operation. It functions as a Power Sourcing Equipment (PSE) and powers devices while providing data connectivity. No driver installation is required for typical PoE devices.
