Powering the Access Point

The AP can be powered using:

• 48 V DC power via the 48VDC port, using Cisco Power Adapter AC DC AIR-PWR-C=. Ensure

that the power cable is routed through the strain relief retention clips cast into the enclosure. See

Figure

• Power-over-Ethernet (PoE) from the Ethernet cable, from an external power source such as the

Cisco Power Injector AIR-PWRINJ4=.You can also use the AIR-PWRINJ5 Cisco Power Injector

but with reduced functionality.

• Any 802.3at (25.5 W) or 802.3af (15.4 W) compliant power injector.

However, when powered by an 802.3af powering source, the AUX and USB ports are disabled.

The 2.4GHz radio will shift to 2x3:2SS operation and the 5GHz radio will remain at full

operation.

With an 802.3at or the AIR-PWR-C= as the power source, the AP provides full operation

including the AUX and USB ports.
