Power supply failure

You can use the LEDs on the power supply to identify a power supply failure. For more information about
the LEDs on a power supply, see HP A58x0AF 650W AC (JC680A) & 650W DC (JC681A) Power
Supplies User Guide.
The LEDs on the power supply are steady green (active) or blinking green (standby) while the power
supply system is correctly working. If the LEDs behave in any other way, verify the following items:
The switch power cord is properly connected.
•
The power source meets the requirement.
•
The operating temperature of the switch is in the normal range and the power supply has good
•
ventilation.
