Fans

The Z9000 system comes from the factory with one PSU and four fan modules

installed in the chassis. If two or more fans are installed and running, the fan

modules are hot-swappable.

The fan speed increases and decreases automatically based on the system's state

and temperature. The switch never intentionally turns off the fans. To see the log

messages, use the show logging command.
