Server Boot Process and Normal Operating State Indicators
A normal server boot process involves two indicators, the service processor (SP) indicator and
the system OK indicator. The process is described below:
1. When the AC power is applied to the server, the service processor (SP) boots. While the
SP boots its indicator blinks at the slow blink rate (for indicator blink rate information, see
“Indicator Blink Rates” on page 43 ), and the system OK indicator is off steady.
2. When the SP has successfully booted, the SP indicator is on steady, and the system OK
indicator blinks at the single blink rate. When the SP indicator is on steady and the system
OK indicator is at the single blink rate, the server is in standby power mode (see “Standby
Power Mode” on page 103 ).
3. When the server is booting (powered on), the system OK indicator blinks at the fast blink
rate, and the SP indicator is on steady. When the server has successfully booted, the system
OK indicator turns on steady. When the system OK indicator and the SP indicator are on
steady, the server is in full power mode (see “Full Power Mode” on page 103 ).
4. For a server in a normal operating state, the green system OK indicator and the green SP
indicator are on steady (no blink).
Locator Indicator On
When the Locator indicator is activated from Oracle ILOM or from the front panel (by pressing
the Locate button), the indicator blinks at the fast blink rate. The indicator assists in finding a
server within a rack of servers (for example, when activated remotely to correctly identify a
server requiring service).
