Will come with different power supply, (15V), but works fine unless you need to power all 8 PoE ports then you will need to up your voltage. Customer service is our goal! Additional Details ------------------------------ Bullet point: The ProSafe FS116P provides power and data from a single point, using Power over Ethernet (PoE) over a single Cat-5 cable. The sixteen Fast Ethernet ports can be used for any 10/100 Mbps link and eight of these ports can supply industry-standard IEEE 802.3af power. Advanced auto-sensing algorithm gives power only to 802.3af end devices, so no need to worry about damaging proprietary PoE or non-PoE equipment. In addition, it discontinues the power when PoE devices are disconnected.
