The power supplies have an indicator that shows whether power is present or
a power fault has occurred.
• Not lit — AC power is not connected.
• Green — In standby mode, indicates that a valid AC source is connected
tothe power supply, and that the power supply is operational. When the
system is on, it also indicates that the power supply is providing DC power
tothe system.
• Amber — Indicates a problem with the power supply.
• Alternating green and amber — When hot-adding a power supply, this
indicates that the power supply is mismatched with the other power supply.
Replace the power supply that has the flashing indicator with a power supply
that matches the capacity of the other installed power supply.
