The Allnet ALL048900V2 is a Power over Ethernet (PoE) injector for Gigabit networks, which powers PoE-capable end devices such as WLAN access points, VoIP phones or surveillance cameras without requiring a direct power supply. The device enables power delivery via the existing network cable, making installation possible at any location without the need for a nearby power socket. The injector is designed for use in the indoor environment and is particularly suitable for networks where only a few ports require PoE power, avoiding the need to purchase a complete PoE switch.

Applications

The ALL048900V2 is used to extend existing networks with PoE functionality. It is especially suitable for integrating PoE end devices into existing networks that do not support PoE. Typical use cases include installing WLAN access points at optimal radio positions, independent of power cabling, or powering IP cameras in areas where no power socket is available. It is also possible to retrofit non-PoE-capable switches with PoE capability, thereby increasing network flexibility.

Functions and Features in Detail

The injector features two RJ45 ports: one for connection to the switch (data) and one for connection to the PoE end device (data and power). The automatic detection of the connected device ensures that only PoE-capable end devices are powered, preventing damage to incompatible devices. The maximum cable length between switch and end device is 100 meters, complying with standard Ethernet specifications. The LED indicators for Power, PoE, Act and Status allow visual monitoring of the operating status.

Technology Explained Simply

The ALL048900V2 supports multiple PoE standards: IEEE802.3af (up to 15.4 W), IEEE802.3at (up to 30 W) and LTPoE++ (up to 90 W). Power is delivered via the network cable (PoE), with the power output adjusted to the connected device. The device requires no manual configuration and is therefore suitable for plug-and-play use. The metal housing ensures high mechanical stability and heat dissipation, increasing operational reliability. The operating temperature ranges from 0 to 40 °C, and the operating humidity is 10 % to 90 % (non-condensing). The device is suitable for wall mounting and can thus be discreetly integrated into network infrastructures.

Compatibility and Accessories

The injector is compatible with devices supporting the IEEE802.3af, IEEE802.3at and LTPoE++ standards. It can be combined with various accessories, such as the ALL048600 PoE Gigabit Repeater PoE++ 90W for signal amplification, the ALL048700 Splitter HPoE 90W for power splitting, or the ALL048605PD Switch unmanaged 4 Port Gigabit LT-PoE 90W for additional PoE ports. The external power supply (100–240 VAC, 56 VDC/2 A) is included in the delivery scope and provides power for the injector.

Installation and Mounting

Installation is performed by connecting the injector to a switch via the data port and to the PoE end device via the power/data port. The device can be mounted on a wall, allowing it to be discreetly integrated into existing network infrastructures. The compact design and metal housing enable robust and discreet mounting.

Operational Advantages

The ALL048900V2 reduces the need for additional power supply cables, enabling flexible placement of PoE end devices. Automatic detection and support for multiple PoE standards increase compatibility. The use of an external power supply ensures stable power delivery, and the metal housing guarantees high operational reliability. The maximum PoE power of 90 W allows powering even high-performance end devices.
