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.

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.
