Power Indicator Codes
The power supplies have an indicator that shows whether power is present or
whether a power fault has occurred.
• Not lit—AC power is not connected.
• Green—In standby mode, indicates that a valid AC source is connected to
the 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
to the 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 (a high output power supply and an Energy Smart power supply are
installed in the same system). Replace the power supply that has the
flashing indicator with a power supply that matches the capacity of the
other installed power supply.
