## Summary description

The LevelOne POI-4000 is a 56W PoE injector designed to power PoE-enabled devices such as IP cameras and wireless access points. It supports IEEE 802.3af/at standards, ensuring compatibility with a wide range of devices. With a compact design and easy installation, it provides a reliable power solution without the need for additional power outlets. Ideal for both home and business use, the POI-4000 enhances network efficiency and simplifies deployment.

## Long description

LevelOne POI-4000(-Z) is a high-power Power Sourcing Equipment (PSE) injector designed for Power over Ethernet applications. It accepts a data-only Ethernet input and provides a combined data-and-power output over Cat5/6/7 cabling, delivering up to 56 watts (60 W peak capability) to support devices that require more power than the IEEE 802.3af limit allows. The unit supports 10/100BASE-T connections and implements IEEE 802.3x flow control to ensure stable data transmission.
Advantages
POI-4000(-Z) supplies significantly higher power than legacy PoE standards, enabling deployment of power-hungry devices such as outdoor access points, IP surveillance cameras and PoE VoIP phones. The injector preserves 100 Mbps wire-speed Ethernet performance while adding power on the output port, and includes built-in protection against over-current and over-voltage conditions for safer operation. Installation is straightforward with plug-and-play connectivity.
Key specifications
Ports: 2 × 10/100BASE-T RJ‑45 (one data-in, one data+power out)
Maximum output power: 56 W (PSE high-power injector; supports up to 60 W over suitable cabling)
Ethernet standard: 10/100 Mbps wire speed
PoE protocol/compatibility: high-power PSE for PoE devices beyond IEEE 802.3af limits
Flow control: IEEE 802.3x
Power protection: OCP (over-current protection), OVP (over-voltage protection)
How to use
Connect the network switch or data source to the injector’s Ethernet input (data only) RJ‑45 port. Connect the powered device (PD) to the injector’s output RJ‑45 port using Cat5/6/7 cable to deliver both data and power. Ensure cabling and PD power requirements are compatible with the injector’s maximum output. The device operates at 100 Mbps wire speed and requires no special configuration; power and data are applied automatically when a compatible PD is connected.
Recommendations
Use quality Cat5e or higher cabling and verify that the powered device supports high-power PoE. For extended distances, pair the injector with PoE repeaters to extend the powered Ethernet link while monitoring total power budget and cable length limits to avoid voltage drop or insufficient power delivery.
