Refer to Power Button, Power/OK LED, and SP Fault/OK LED when completing the following procedure.
Shortly after power is applied to the server, the SP OK/Fault LED blinks as the service processor boots. The SP OK/Fault LED is illuminated solid green when the service processor has successfully booted. After the service processor has booted, the Power OK/LED on the front panel begins flashing slowly, indicating that the host is in standby power mode.
When main power is applied to the server, the main Power/OK LED begins to blink more quickly while the system boots and lights solidly once the operating system boots.
Each time the server powers on, the power-on self-test (POST) can take several minutes to complete.
