Mode Button

The mode button is used for resetting the switch, entering express setup mode, selecting or changing an LED
mode, and manually waking up the switch from hibernation mode.
In Cisco Catalyst Digital Building series switches, LEDs are normally turned off to save power. When the
mode button is pressed, the LEDs turn on for a set period (60 seconds) before they turn off again to save
power. This can be overridden by a configuration parameter which alters the default 60 second timeout or
disables LED power savings completely. All LEDs are affected by this function except the System LED,
which only dims and does not turn off completely.
