Power Dsine 3524 Power over Ethernet (Po E) Midspan offers a cost effective, fully IEEE 802.3af compliant solution to upgrade existing infrastructure with Po E. Power Dsine 3524 allows network devices to receive power, along with data, over standard Ethernet cables, leaving network infrastructure completely unaltered. With Po E, data & power flow smoothly & safely over a single LAN cable with no interference. A Po E Midspan (Po E injector) resides between the Ethernet switch & the data terminals, delivering data, along with power, from switch to powered devices. It is a highly effective means for injecting power into existing LAN cables.
