The PoE ports provide up to 15.4 W of power to connected Cisco prestandard and IEEE 802.3af-compliant powered devices if the switch detects that there is no power on the circuit. On a per-port basis, through the Cisco Configuration Assistant, you can control whether the PoE port automatically provides power when a powered device is connected. By default, the setting is Auto.

Use the Cisco Configuration Assistant to change the port settings.
