9.1.2.1
System Status LED – BMC Initialization
When AC power is first applied to the system and 5V-STBY is present, the BMC controller on
the server board requires 30-35 seconds to initialize.
During this time, the system status LED
will blink, alternating between amber and green, and the power button functionality of the control
panel is disabled, preventing the server from powering up.
Once BMC initialization has
completed, the status LED will stop blinking and the power button functionality is restored and
can be used to turn on the server.
