Usage guidelines

When the auto power-down function is enabled on an interface and the interface has been down for a certain period of time, both of the following events occur:

• The switch automatically stops supplying power to the interface.

• The interface enters the power save mode.

The time period depends on the chip specifications and is not configurable.

When the interface comes up, both of the following events occur:

• The switch automatically restores the power supply to the interface.

• The interface enters its normal state.
