• The cooling system is designed such that, during normal operation, the fans typically run at

somewhere between 40 and 50 percent of their maximum speed at 26°C ambient temperature. This

feature results in lower noise and higher average fan life. The switch increases the fan speed to

maximum if the facility air condition fails or if a fan fails.

• The fan speed increases and decreases automatically based on the internal temperature. The switch

never intentionally turns off the fans.

• For proper ventilation, position the switch in an equipment rack (or cabinet) with a minimum of 5

inches (12.7 cm) of clearance around the exhaust vents. When you install two systems near each

other, position the two chassis at least 5 inches (12.7 cm) apart to permit proper airflow. The

acceptable ambient temperature ranges are listed in Technical Specifications.

Installing AC Power Supplies

The chassis requires four power supplies to be installed for normal configuration. The airflow direction

must be from I/O to Utility.

Important Points to Remember for Installing an AC Power Supply

• The power supply unit (PSU) slides into the slot smoothly. Do not force a PSU into a slot as this action

may damage the PSU or the chassis.

• The chassis supports AC power supplies with air-flow direction from I/O to Utility.
