Step 8 Secure the cable in the power supply receptacle by pushing the cable retention clip until it snaps into
place around the cable connector.
Step 9 Connect the opposite end of the power cable to an appropriate power source.
Caution Do not turn on any power supplies until you are ready to power up the system. The interlock switch that
locks the power supply in the slot also turns on the system power.
If you are installing a second power supply, repeat Step 2 through Step 9. We recommend you connect
the second power supply to a secondary power source for redundancy.
Note To prevent system problems, do not mix AC-input and DC-input power supplies in the same chassis.
