The Cisco Aironet Power Injector increases wireless LAN deployment flexibility by providing an alternative powering option to local power, inline power-capable multiport switches, and multiport power patch panels.The single-port Cisco Aironet Power Injector combines 48-VDC power (supplied by the external power supply) with the data signal, sending both to the Cisco Aironet Access Point and to Bridge.Depending on the model, the power injector provides up to 15 watts over the unused wire pairs of a Category 5 Ethernet cable, supplying enough power for a distance of 100 meters on the Cisco Aironet 350, 1100, and 1200 Series access points and Cisco Aironet 350 Series bridges.
