The Pro Safe FS108P provides power & data from a single point, using Power over Ethernet (Po E) over a single Cat-5 cable. The eight Fast Ethernet ports can be used for any 10/100 Mbps link & four 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 Po E or non-Po E equipment. In addition, it discontinues the power when Po E devices are disconnected. Easy & reliable, the Pro Safe FS108P automatically determines Po E requirements, speed, duplex, & cable type using Auto Uplink.
