Both and DC-input Both the AC-input power and DC-input power supplies support redundancy. When
power is removed from one supply, the redundant power feature causes the second supply to produce full
power.
For power supply LED descriptions, see the “Environmental Monitoring of the Power Supply” section
on page 1-32. For complete power specifications, see Appendix A, “Technical Specifications.”
