b) Bring the new network module online using the appropriate CLI command (if the new network module supports hot

Remove and Replace the Fan Module

You can remove and replace fan modules while the system is running. The air flow moves from front to back.
If you remove a fan or a fan fails, the other fans operate at full speed, which can be noisy.
Note
The system supports operation with a single fan failure (N+1 fan redundancy), but do not run the system for
an extended amount of time without all fan modules installed. Keep removal and replacement time at three
minutes. Remove and replace one fan module at a time.
