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 USB port is disabled. Both radios

operate at full operation.

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

including the USB port.
