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 3 minutes.
Remove and replace one fan module at a time.
