Description
• Green: The power supply is connected to the ac power source.
• Off: The power supply is disconnected from the ac power source or a power problem
occurs.
• Green: The server is on and the power supply is working normally.
• Blinking green: The power supply is in the zero-output mode (standby). When the
server power load is low, one of the installed power supplies enters the standby state
while the other one delivers the entire load. When the power load increases, the
standby power supply will switch to the active state to provide sufficient power to the
server.
To disable the zero-output mode, start the Setup utility, go to System Settings ➙
Power ➙ Zero Output, and select Disable. If you disable the zero-output mode, both
power supplies will be in the active state.
• Off: The server is turned off, or the power supply is not working properly. If the server is
turned on but the power output LED is off, replace the power supply.
• Yellow: The power supply has failed. To resolve the issue, replace the power supply.
• Off: The power supply is working normally.
