Caution -
Do not operate the server without all fans, component heat sinks, air baffles, fillers,
and the cover installed. Severe damage to server components can occur if the server is operated
without adequate cooling mechanisms.
1. Verify that the power cords are connected and that standby power is on.
Shortly after power is applied to the server, the SP OK/Fault LED blinks as the SP boots. The
SP OK/Fault LED is illuminated solid green when the SP has successfully booted. After the SP
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 server boots and lights solidly once the operating system boots.
Each time the server powers on, POST can take several minutes to complete tests.
