22 About Your System
• 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 870-W power supply and an Energy Smart 570-W
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.
