Connecting The System To Power Figure 6. Connecting Power to the System Connect the system's power cables to the system power supplies. CAUTION: To prevent the power cables from being disconnected accidentally, use the plastic clip on each power supply to secure the power cable to the power supply, and use the strap to secure the power cable to the strainrelief bar. CAUTION: Do not plug the power cables directly into a power outlet; you must use a PDU. For optimal system functionality, a minimum of three power supplies are required. Plug the other end of the power cables into a power distribution unit (PDU). NOTE: The power supply units must have the same maximum output power. Turning On The Enclosure Figure 7. Enclosure Power Button Press the power button on the enclosure. The power indicator should light. NOTE: Once you have connected the system to the power supplies, there may be a minimal delay before you can turn on your system. 6
