Displaying The Operating State Of Fans - HP 12500 Series Installation Manual

The hardware-failure-protection aggregation and hardware-failure-protection auto-down commands
do not take effect on an interface in the following cases:

•
The interface is forcibly brought up (using the port up-mode command).
•
• The interface is a physical IRF port. For more information about physical IRF ports, see IRF
Configuration Guide.

interface command to view the status. To restore the interface to UP state, execute the undo shutdown
command.
For a card that is isolated or forbidden to load software for hardware failure protection, you can remove
it and then reinstall it to restore it to operating state.
