Cisco Aironet Power Injector products increase the deployment flexibility of Cisco Aironet wireless access points & bridges by providing an alternative powering option to local power, inline power-capable multiport switches, & multiport power patch panels. The single-port Cisco Aironet power injectors combine 48-VDC power with the data signal, sending both to the Cisco Aironet access point or bridge. Cisco Aironet 350 Series access points & bridges include an integrated power supply & injector (AIR-PWRINJ). The power injector for Cisco Aironet 1100 & 1200 series access points (AIR-PWRINJ3) works with the power supply provided with the access point. The Cisco Aironet Power Injector Media Converter (AIR-PWRINJ-FIB) converts fiber media to Category 5 media & combines the resulting data signal with power for delivery to the access point or bridge. The power injector media converter accepts 48 VDC power from either the barrel connector of the local power supply or an alternative 48 VDC power source. When powered by an alternate 48 VDC power source connected using the provided power supply pigtail, the Power Injector Media Converter is UL2043 certified & suitable for installation in environmental air spaces. The local power supply is provided with the Cisco Aironet 1100 & 1200 series access points, while applicable local power supplies for the Cisco Aironet 350 Series access points & bridges are available separately. The power injectors provide up to 15 watts (depending on the Cisco power supply model) over the unused wire pairs of a Category 5 Ethernet cable, supplying enough power to provide for up to a 100-meter cable run. ...
