Messages Displayed at the Startup Screen

If you configure the shutdown feature and a hardware 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.
