Advanced System Diagnostics and Troubleshooting Guide
Diagnostics
Table 6 describes the behavior of the switch if you run diagnostics manually using the 
run diagnostics
 CLI command with the 
normal
 option. The behavior differs based on the hardware 
configuration, the mode selected (online or offline) using the 
configure sys-health-check
 CLI 
command, and the number of errors to be detected.
