Cisco Power Injector for Cisco Aironet 2800/3800 Access Points


The Cisco Aironet Power Injector AIR-PWRINJ6= increases wireless LAN deployment flexibility of supported 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 Cisco access points requiring 802.3at power input.

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.
