Cisco Aironet Power Injector AIR-PWRINJ6= GuideAIR-PWRINJ6=
This document describes the Cisco Aironet series access point power injector AIR-PWRINJ6= (referred to asAIR-PWRINJ6=
the power injector in this document) and provides instructions for mounting them.
Product Overview
The Cisco Aironet Power Injector AIR-PWRINJ6= increases wireless LAN deployment exibility of supportedAIR-PWRINJ6=
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 PoE injector provides up to 30 Watts and is compliant with IEEE 802.3af (15.4 W) and IEEE
802.3at (30 W) systems. This power injector is for use with the Cisco Aironet 2800 series and 3800 series
access points.
Note The Cisco Aironet Power Injector AIR-PWRINJ6= is not weatherproof and hence is not meant to beAIR-PWRINJ6=
used outdoors.
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 C13 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.

1. There are two AIR-PWRINJ6 models, each provided by dierent suppliers. They are functionally
identical even though they have minor cosmetic dierences. Depending on the model, the Status
LED will be on the right instead of the left.
The Status LED indicates the following system status events:
AC Power - Depending on the model, the LED is amber or blinks green 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 or 802.3at load (AP) is
detected and powered ON. The LED remains green when powering the Access Point even if the uplink is
not connected. The LED is green for showing that the power injector is providing power to the Access
Point.
Figure 2 shows a typical 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.
The AIR-PWRINJ6= should not be installed in the plenum airspace.
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.
Disable PoE on the Connected Switchport
Sometimes, when the AP is connected to the AIR-PWRINJ6 that is cabled to a 802.3af PoE-enabled
switchport, it might not function properly. To resolve this, disable PoE on the switchport connected to the
AIR-PWRINJ6= injector.AIR-PWRINJ6=
Failure to do so will result in the injector not supplying full power to the AP and might cause issues such as
disabled radios since the AP will intermittently receive only 15.4W of power.
To disable PoE on the connected switchport, execute the power inline never command at the CLI prompt of
the Cisco switch when it is in the interface config mode.

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.
2. Plug the other end of the Ethernet cable into the WAN uplink Ethernet port of the access point.
3. Plug a Category-5 Ethernet cable into the port on the power injector labeled Switch.
Note Ensure that PoE is disabled on this switchport before it is connected to the AIR-PWRINJ6= injector.AIR-PWRINJ6=
For more information, go to Disable PoE on the Connected Switchport
4. Plug the other end of the Ethernet cable into your 10/100/1000 Ethernet switch, hub, or network.
5. When power is applied, the Status LED is amber. When the AP is detected, the Status LED glows solid
green.
6. Secure the power injector by mounting it to a vertical or horizontal surface using the mounting keyholes
on the bottom of the unit.
Mounting Instructions
You can mount the power injector to most vertical or horizontal surfaces using the mounting tabs on the top
right and bottom left of the unit.
Using the Mounting Tabs
To mount the power injector to a vertical or horizontal surface using the mounting tabs, you will need the
following parts and tools:
Two #6 plastic wall anchors if mounting to a drywall surface
Two #6 x 1-in. (2.5 cm) sheet-metal screws
A drill and a 3/16-in (0.48-cm) drill bit
A Phillips head screw driver
A small hammer
Follow these steps to mount the power injector:
1. Using the holes in the power injector mounting tabs as a template, mark the locations on the surface
where you will drill the holes for the wall anchors or screws.
2. Drill a 3/16-in. (4.7-mm) hole at each marked location.
3. If you are using #6 wall anchors, use a hammer to install them in the holes.
4. Hold the power injector to the wall and align the mounting tabs on the power injector with the screw
holes.
5. Insert the #6 screws through the mounting tabs and into the holes in the wall or surface.
6. Use a Phillips head screwdriver to drive the screws into the surface.
