Four power supplies must be installed in the chassis at all times, with a minimum of two power supplies (one
per zone) connected to the mains in order to power on the system and ensure sufficient cooling. The system
fans are inside the power supply units and must spin for cooling. Because all the system fans can be powered
by one power supply, the second power supply unit does not have to be powered on, but must be connected.
Note
If you remove a power supply from a system that has four power supplies that are connected and powered
on, the system can run only for a maximum of five minutes before shutting down. However, because the fans
and power elements are independent within the power supply, the replacement power supply does not have
to be energized within five minutes. The only requirement is that the power supply be installed in the chassis
in order to energize the fans and maintain proper system cooling.
Caution
Step 6
Grasping the power supply handles, pull the power supply from the chassis.

Replace the AC power supply within five minutes.
