•
Before you connect a chassis power supply to an AC power source, ensure all of the following:
• There is a vacant receptacle on the AC power source within reach of the chassis power supply cable.
• The power supply is already installed in the chassis.
• The chassis is connected to an earth ground.
Note
Step 1 Ensure that the power supply switch located on the front of the power supply is set at standby (labeled as 0).
Step 2
Plug one AC power cable into the power supply, and pull down the retention clip over the plug on the power cable.
Step 3 Plug the other end of the power cable into a AC power source supplied by the data center.
To reduce risk of electric shock and fire, take care when connecting units to the supply circuit so that wiring

Warning This product relies on the building's installation for short-circuit (over current) protection. To reduce risk of
electric shock or fire, ensure that the protective device is rated not greater than: 250V, 20 A. Statement 1005.
Step 4
Turn the power supply switch from standby to on (from 0 to 1 as labeled on the power switch).
Step 5 Verify that the power supply is receiving AC power and outputting DC power by making sure that the INPUT and
OUTPUT power supply LEDs are lit and the FAULT LED is not lit or flashing. For an explanation of all the power
supply LEDs and the conditions that they indicate, see
When you first activate the power supply, you can verify the functionality of the LEDs by checking that each
