Power Indicator Codes The power supplies have indicators that show whether power is present or whether a power fault has occurred. • Not lit-AC power is not connected. • Green-In standby mode, a green light indicates that a valid AC source is connected to the power supply and that the power supply is operational. When the system is on, a green light 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. CAUTION: When correcting a power supply mismatch, replace only the power supply with the flashing indicator. Swapping the opposite power supply to make a matched pair can result in an error condition and unexpected system shutdown. To change from a High Output configuration to an Energy Smart configuration or vice versa, you must power down the system. 20 About Your System

About Your System
Power Indicator Codes
The power supplies have indicators that show whether power is present or
whether a power fault has occurred.
•
Not lit—AC power is not connected.
•
Green—In standby mode, a green light indicates that a valid AC source is
connected to the power supply and that the power supply is operational.
When the system is on, a green light 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.
CAUTION:
When correcting a power supply mismatch, replace only the power
supply with the flashing indicator. Swapping the opposite power supply to make a
matched pair can result in an error condition and unexpected system shutdown.
To change from a High Output configuration to an Energy Smart configuration or
vice versa, you must power down the system.
