Cisco Aironet Power Injector (AIR-PWRINJ5) Installation Guide
Preface
The Cisco Aironet Power Injector (AIR-PWRINJ5) increases wireless LAN deployment exibility 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 su cient power to supply to the AP and any installed modules.
This guide covers the following Cisco Aironet Power Injector:
