The access point can be powered from the 48-VDC power module or from an in-line power source. The
access point supports the IEEE 802.3af power standard for in-line power sources.
access point supports the IEEE 802.3af power standard for in-line power sources.
For operation, the access point (powered device) requires 12 W of input power.
Note
When the access point is being used in a PoE configuration, the power drawn from the power sourcing
equipment (PSE), such as a switch or power injector, is higher by an amount dependent on the length of
the interconnecting cable.

The power module (AIR-PWR-1000=) and the Cisco Aironet power injector (AIR-PWRINJ-1000af=)
are capable of supplying the required operating power, but some inline power sources are not capable of
supplying sufficient power. Also, some high-power inline power sources, might not be able to provide
sufficient power to all ports at the same time.

Note
If your access point is connected to in-line power, do not connect the power module to the access point.
On power up, the access point is placed into low power mode (both radios are deactivated), the access
point power negotiation determines if sufficient power is available. If there is sufficient power then the
access point begins to power up (Alarm LED is red and other LEDs are off); otherwise, the access point
turns off all LEDs and remains in low power mode to prevent a possible over-current condition.
