The fix actions taken in case of hardware
failures include:
• Off—Takes no action.
•
Warning—Sends warning messages.
• Reset—Resets the failed card.
•
Isolate—Shuts down the failed port,
isolates the failed card, prohibits the
failed card from loaded, or powers off
the failed card to reduce the impact of

action taken for all hardware failures is
warning.
