Step Task 1 Remove the small plastic cover from the DC connectors. 2 Ensure that the power source is turned off. Do not attach the DC cable to the DC connectors while the power source is on. 3 Attach the connectors to the PSUs, making sure that the connections are secure. 4 Replace the plastic cover over the DC connectors. 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.
