10 Installing the Hardware
As soon as the cable is connected between the Z9000 and the power source, the 
chassis is powered-up; there is no on/off switch.
Fans
The Z9000 comes from the factory with 1 power supply and 4 fan modules 
installed in the chassis. The fan modules are hot-swappable, if 2 or more fans are 
installed and running.
The fan speed increases and decreases automatically based upon the system's 
state and temperature. The switch never intentionally turns off the fans. Use the 
show logging command to see the log messages.
