Messages Displayed at the Startup Screen

If you configure the shutdown feature and an error is detected, the system displays an explanatory message on the startup screen.

The following truncated sample output shows the startup screen if a stand-alone switch is shut down as a result of the hardware recovery configuration:
All switch ports have been shut down.
Use the "clear sys-recovery-level" command to restore all ports.
! SummitX.1 # 

When an exclamation point (!) appears in front of the command line prompt, it indicates that the entire stand-alone switch is shut down as a result of your hardware recovery configuration and a switch error.
