Solution
To resolve the problem:
1.
Verify that you can access the CLI after the switch reboot.
If you can access the CLI, execute the display diagnostic-information command to collect log
messages.
If you cannot access the CLI, go to step 2.
2.
Verify that the system software image on the switch is correct.
a.
Log in to the switch through the console port and restart the switch. If the system reports that a
CRC error occurs or that no system software image is available during the BootWare loading
process, reload the system software image.
b.
Verify that the system software image in the flash memory is the same as the one on the server.
If no system software image is available in the flash memory, or if the image is different than
the one on the server, reload the system software image. Then set the reloaded system software
image to the current system software image. The system software image in the flash memory is
automatically set to the current system software image during the BootWare loading process.
