Powering On the Oracle Exadata Rack
For instructions on how to power on the Oracle Exadata Rack, refer to the Oracle Exadata Database Machine Installation and Configuration Guide at https://docs.oracle.com/cd/E80920_01/index.htm.
 | Caution - Do not connect the power cords to the storage server until you have made the service processor (SP) and host networking cable connections. The storage server includes an SP that you use to configure and boot the host system. Connecting the SP and host networking cables first enables you to properly configure the host system and view SP messages. |
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 you connect AC power to the server, the server boots into standby power mode:
-
The SP OK LED blinks slowly (0.5 seconds on, 0.5 seconds off) while the SP is starting, and the main System OK LED remains off until the SP is ready.
-
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 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 Main power mode:
-
The System OK LED blinks slowly (0.5 seconds on, 0.5 seconds off), and the SP OK LED remains lit (no blinking).
-
When the server successfully boots, the System OK LED remains lit. When the System OK LED and the SP OK LED indicators remain lit, the server is in Main power mode.
Note - The green System OK LED indicator and the green SP OK indicator remain lit (no blinking) when the server is in a normal operating state.
