Cisco - PoE injector

The Cisco Aironet Power Injector (AIR-PWRINJ5) increases wireless LAN deployment flexibility of Cisco Aironet Access Points 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 provides 802.3 af power and data signal, sending both to the Cisco Aironet Access Point. The power injectors provide up to 15.4 watt over the unused wire pairs of a Category 5 or better Ethernet cable, supplying enough power for a distance of 328 feet (100 metres) on the Cisco Aironet 1040, 1140, 1260, 2600, and 3500 Series Access Points. While it can also support the Cisco Aironet Series 3600 Access Points when modules are not being used, it is recommended to use the AIR-PWRINJ4= power injector instead for the 3600 series, as it has sufficient power to supply to the AP and any installed modules.
