1. Verify that the power cord has been connected to the server and that standby
power is on.
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.
2. Press and release the recessed Power button on the server front panel.
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.
