Cisco Aironet Power Injector
(AIR-PWRINJ5) Installation Guide
Preface
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.
This guide covers the following Cisco Aironet Power Injector:

The Cisco Aironet Power Injector provides both power and data to a connected Cisco Aironet Access
Point. The device serves the following functions:
•
It provides Category 5 or better Ethernet media to the access point.
•
It uses wires in an Ethernet cable to supply inline 15.4 W power to an access point. The power
injector provides an easy and economical way to provide data and power to an access point located
in areas where power is not available.
The power injector is used with the following Cisco Aironet Series Access Points:
•
1040 series access points
•
1140 series access points
•
