The following truncated sample output shows the startup screen if any of the slots in a modular switch are shut down as a result of the system recovery configuration:
The I/O modules in the following slots are shut down: 1,3 Use the "clear sys-recovery-level" command to restore I/O modules ! BD-8810.1 #
When an exclamation point (!) appears in front of the command line prompt , it indicates that one or more slots shut down as a result of your system recovery configuration and a switch error.
