How to Configure PoE
Configuring a Power Management Mode on a PoE Port
When you make PoE configuration changes, the port being configured drops power. Depending on the
new configuration, the state of the other PoE ports, and the state of the power budget, the port might not
be powered up again. For example, port 1 is in the auto and on state, and you configure it for static mode.
The switch removes power from port 1, detects the powered device, and repowers the port. If port 1 is in
the auto and on state and you configure it with a maximum wattage of 10 W, the switch removes power
from the port and then redetects the powered device. The switch repowers the port only if the powered
device is a class 1, class 2, or a Cisco-only powered device.
