Troubleshoot Hardware Faults Using the Oracle ILOM Web Interface
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 Power/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 main Power/OK LED remains off until the SP is ready.
2. After a few minutes, the main Power/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 Power button or Oracle ILOM), the server boots to
full power mode:
1. The Power/OK LED blinks slowly (0.5 seconds on, 0.5 seconds off), and the SP OK LED
remains lit (no blinking).
2. When the server has successfully booted, the Power/OK LED remains lit. When the Power/
OK LED and the SP OK LED indicators remain lit, the server is in full power mode.
Note - The green Power/OK LED indicator and the green SP OK indicator remain lit (no
blinking) when the server is in a normal operating state.
Server System-Level Status Indicators
There are seven system-level status indicators (LEDs), some of which are located on both the
server front panel and the server back panel. The following table describes these indicators.
