How Can I View Built-in Fan Information?
To view information about built-in fans, run the
display fan command. A device has no fan subcard but has built-in fans if both
of the following situations occur:
- No fan information is displayed when you run the display device command.
- The Online field displays Present when you run the display fan command.
The following is an example of the command output.
