Figure 1 Troubleshooting unexpected switch reboot
Solution
To resolve the problem:
1. Verify that you can access the CLI after the switch reboots.
{ 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.
Log in to the switch through the console port and restart the switch. If the system reports that a CRC
error has occurred or that no system software image is available, reload the system software
image. The system software image is automatically set to the current system software image during
the Boot ROM image running process.
3. If the problem persists, contact H3C Support.
