LevelOne Gigabit PoE Injector, 802.3at/af PoE, 30W

The LevelOne POI-3000 is a single-port, high-power PoE PSE injector that delivers up to 30W over two pairs to power remote PoE PD devices. Designed for devices such as wireless access points, PTZ IP cameras and videophones, the POI-3000 complies with the IEEE 802.3at (PoE+) standard and is backward compatible with IEEE 802.3af. The unit supports connection to 10/100/1000Base-T networks and provides a reliable high-bandwidth link while simplifying network deployment.

Advantages

The POI-3000 supplies up to 30W to a single device while remaining IEEE 802.3at compliant and compatible with legacy IEEE 802.3af equipment. It includes automatic detection and protection for non‑standard Ethernet terminals, preventing damage to low-power devices by supplying only the power they require. The injector supports current and emerging Ethernet speeds, offers a straightforward interlocking mounting feature for easy installation, and reduces installation complexity and downtime.

Key specifications

• Power output: up to 30W over 2 pairs
• Standards: IEEE 802.3at compliant, backward compatible with IEEE 802.3af
• Supported LAN: 10/100/1000Base-T
• Port count: single PoE PSE port

How to use

Connect the POI-3000 to a power source and link its data input to your network switch or router using a standard Ethernet cable. Attach the powered output port to the PoE device (for example, an access point or PTZ camera). The unit will automatically detect the connected device and supply appropriate power while maintaining data transmission. Ensure cable type and length meet the device manufacturer recommendations for reliable operation.

Recommendations

Use Category 5e or better cabling for gigabit-capable setups, verify device PoE class compatibility before connection, and mount the injector in a ventilated location away from direct heat sources to ensure stable performance and longevity.
