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:
• Cisco Aironet Power Injector (AIR-PWRINJ5)
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
• 1260 series access points

• 2600 series access points
• 3500 series access points
A Category 5 or better Ethernet cable connects the injector to a 10/100/1000 Ethernet switch, hub, or
network, and another cable carries power and data to the access point's WAN Ethernet port. The power
injector’s built-in power supply has a C14 connector that connects to a wall outlet or power strip. The
power injector connects to a wall outlet or power strip.
Caution To avoid overheating and possible failure, do not stack or tie together (bundle) the power injector and its
AC power cable.
Figure 1 shows the key features of the power injector.

The Status LED indicates the following system status events:
• AC Power - The LED blinks green at approximately 1.5 times per second to indicate that the Power
Injector is powered ON and ready for connection.
• AP Power - The LED lights solid green to indicate that a valid IEEE 802.3af load (AP) is detected
and powered ON.
• Invalid load connected or Fault: The LED rapidly blinks green at 10 times per second to an invalid
load connected or a Fault. In these conditions the AP has not been powered on. This occurs for 2
seconds for normal error delay, and the detection process will automatically start again after 2.2
seconds unless there is a “restart after disconnect condition” set during the initial configuration.

Cisco Aironet Power Injector (AIR-PWRINJ5) Installation Guide
Installing the Power Injector
Figure 2 shows a typical installation scenario.
Figure 2 Power Injector AIR-PWRINJ5 Installation Scenario
Unpacking the Power Injector
The typical power injector package contains the following items:
• Power injector
• Power cord
• URL Pointer Card and China RoHS Statement
If any item is missing or damaged, contact your Cisco representative or reseller.
Additional Requirements
Use the power cord that shipped with your power injector to supply power for the injector. If you install
the access point in an environmental air space such as above a suspended ceiling, check national and
local safety codes to make sure that the Ethernet cable you connect to the unit meets applicable
standards.
Note The AIR-PWRINJ5 is not plenum and should not be installed in the plenum airspace.
Note The maximum distance that is supported for in-line power is 328 ft. (100 m), including the length of the
6.5-ft. (2-m) Ethernet cable provided with the power injector.
Installing the Power Injector
Follow these steps to install the power injector:
1. Plug a Category-5 Ethernet cable into the port on the power injector labeled AP.
