Cisco AIR-PWRINJ5 Power Injector (802.3af) for AP 1600, 2600 and 3600

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 802.3af power and data signal, sending both to the Cisco Aironet Access Point.
The power injectors provide up to 15.4 W over the unused wire pairs of a Category 5 or better Ethernet cable, supplying enough power for a distance of 328 ft. (100 m) 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.
The power injector is used with the following Cisco Aironet Series Access Points:
1040 series access points
1140 series access points
1260 series access points
1600 series access points
2600 series access points
3500 series access points
