PoE Midspan Injector 30W (802.3at) HP Aruba Instant On — Grey, 100–240V, 50/60Hz, 89×51×61mm

The HP Aruba Instant On PoE Midspan Injector 30W (802.3at) is a compact power-over-Ethernet adapter designed to supply up to 30 watts of DC power to compatible network devices while carrying data on a single Ethernet cable. The injector supports IEEE 802.3at (PoE+) standard and is intended for use with access points, IP phones and PoE-capable cameras that require higher power than standard PoE. The unit accepts a wide AC input voltage range and is housed in a grey enclosure sized for desktop or near-rack placement.

Advantages

This PoE midspan injector delivers up to 30 W per port in compliance with the IEEE 802.3at specification, ensuring predictable power delivery for PoE+ devices. Its universal AC input allows operation from 100–240 V at 50/60 Hz, making it suitable for diverse installation sites. The small footprint (89 × 51 × 61 mm) saves space and enables discreet positioning close to network equipment. The device separates power sourcing from network switches, allowing standard switches to provide data without PoE capability while the injector supplies required power.

Suitable for

• Powering Wi‑Fi access points that require PoE+ (802.3at) support
• Supplying power to IP desk phones or intercoms with PoE compatibility
• Delivering power to PoE-enabled security cameras and edge devices
• Adding PoE capability to non‑PoE switches in small office or retail deployments

Key specifications

• PoE standard: IEEE 802.3at (PoE+), up to 30 W output
• AC input: 100–240 V, 50/60 Hz
• Form factor: compact grey enclosure measuring 89 × 51 × 61 mm
• Connection: Ethernet data + power over single cable (midspan injector configuration)
• Mounting: suitable for desktop or adjacent-to-rack placement

How to use

Install the injector near your network switch or device to minimize cable length. Connect the injector’s AC power cord to a mains outlet within the specified voltage range. Use a standard Ethernet patch cable from the network switch to the midspan injector input and run another Ethernet cable from the injector output to the PoE-capable device. Verify that the powered device supports IEEE 802.3at to ensure proper negotiation and power delivery. Ensure firmware or software monitoring on managed devices is configured to reflect the new power source if applicable.

Usage recommendations

Place the injector in a ventilated area and avoid covering the enclosure to maintain thermal dissipation. Use certified Ethernet cabling (Cat5e or higher) for reliable data and power transmission, and keep cable runs within recommended lengths for PoE deployment. For installations with multiple PoE devices, plan power budgeting to avoid exceeding the injector’s 30 W output.
