["With the ALLNET ALL048900V2 HighPower PoE injector you can install your PoE-capable IP devices such as WLAN access points, VoIP telephones and much more completely independently of existing power sockets. For example, the most ideal installation locations in a building can be selected for WLAN access points without having to pay attention to the power cabling. Switches that are not PoE-capable can be \"retrofitted\" with Power over Ethernet at low cost, especially if you only need a few ports with PoE supply. Here the ALL048900V2 saves you the expensive purchase of a PoE switch. The ALLNET ALL048900V2 supports the IEEE802.3af standard with a power of 15.4 watts, the IEEE802.3at high power standard with 30 watts and the IEEE802.3at++ with 90 watts of power. The ALL048900V2 does not need to be configured. It has an RJ45 input socket and an RJ-45 output socket, via which the switch and end device are connected to the PoE injector. As is usual in Ethernet, the cable length can be up to 100 meters in total between the switch and the end device. Thanks to its compact design and metal housing, the ALL048900V2 can be installed very inconspicuously and is extremely robust.
