Important Points to Remember
You can only perform offline diagnostics on an offline standalone unit or offline member unit of a 
stack of three or more. You cannot perform diagnostics on the management or standby unit in a stack 
of two or more (
).
Perform offline diagnostics on one stack member at a time.
Diagnostics only test connectivity, not the entire data path.
Diagnostic results are stored on the flash of the unit on which you performed the diagnostics.
When offline diagnostics are complete, the unit or stack member reboots automatically.
