Checking Hardware after an Upgrade Failure
You can perform a few basic checks if you suspect a hardware failure.
When the system resets as the result of an upgrade failure, you may see output similar to the following example.

hardware and memory, enter the
powercyclecommand at the boot prompt. This causes the system to execute a cold boot.
