Server Boot Process and Normal Operating State Indicators
A normal server boot process involves two indicators, the service processor SP OK LED
indicator and the System OK LED indicator.
When AC power is connected to the server, the server boots into standby power mode:
1. The SP OK LED blinks slowly (0.5 seconds on, 0.5 seconds off) while the SP is starting,
and the System OK LED remains off until the SP is ready.
2. After a few minutes, the main System OK LED slowly flashes the standby blink pattern
(0.1 seconds on, 2.9 seconds off), indicating that the SP (and Oracle ILOM) is ready for
use. In Standby power mode, the server is not initialized or fully powered on at this point.
When powering on the server (either by the On/Standby button or Oracle ILOM), the server
boots to full power mode:
1. The System OK LED blinks slowly (0.5 seconds on, 0.5 seconds off), and the SP OK LED
remains lit (no blinking).
