In a system with dual power supplies, connect each power supply to a separate input source. In case

Verify the power supply operation by checking that the power supply LEDs are in the following states:
• INPUT OK LED is green
• FAN OK LED is green
• OUTPUT FAIL LED is not lit
If the LEDs indicate a power problem, see the “Identifying Startup Problems” section on page E-3 for
troubleshooting information.
