Lower than 16.8 W

Using the AC Power Adapter

If you use the AC power adapter to provide power to the access point, you do not need to adjust the access
point configuration.

Using a Switch Capable of IEEE 802.3af Power Negotiation

If you use a switch to provide PoE to the access point and the switch supports the IEEE 802.3af power
negotiation standard, select Power Negotiation on the System Software: System Configuration page.

Using a Switch That Does Not Support IEEE 802.3af Power Negotiation

If you use a switch to provide Power over Ethernet (PoE) to the access point and the switch does not
support the IEEE 802.3af power negotiation standard, select Pre-Standard Compatibility on the
System Software: System Configuration page.

Using a Power Injector

If you use a power injector to provide power to the access point, select Power Injector on the System
Software: System Configuration page, and enter the MAC address of the switch port to which the access
point is connected.

1250 Series Power Modes

The 1250 series access point can be powered by either inline power or by an optional AC/DC power
adapter. Certain radio configurations may require more power than can be provided by the inline power
source. When insufficient inline power is available, you can select several options (based upon your
access point radio configuration) as shown in the following table:
