Oracle X10 - Power on the Server

WARNING:
For accurate component identification, see Illustrated Back Panel Components
Breakdown.
Pay special attention to the cable routing of PS 0 and PS 2 . These are on the left
side when facing the rear of the system. Cables must be routed and secured away
from the power supply fans to avoid interference with the airflow. The slightest
obstruction will result in overheating warnings.
Power On the Server
1. As soon as you connect the power cords, the server enters Standby power mode and
service processor (SP) starts. Check the following:
• The AC Power Supply indicator lights are steady on.
• The main System OK LED remains off until the SP completes its boot process This
can take a few minutes.
• Once the SP has successfully completed its boot process, 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.
The server is now In Standby power mode. The server host is off.
Note:
Depending on the firmware configuration, the system might automatically boot
the server host at this point. If it does not, proceed to the next step.
2. From the Service Enclave, issue the Start command.
See Hardware Administration in the Oracle Private Cloud Appliance Administrator Guide.
• Service Web UI: In the Rack Units table, click the action menu (three vertical dots) and
select Start.
• Service CLI: Enter the command start ComputeNode id=<node-id> .
3. If the Start command from the Service Enclave does not cause the node to boot as
expected, try these alternatives:
• Press the On/Standby button on the front bezel.
By default, the front panel On/Standby button is disabled. Log in to the ILOM, go under
SP/policy and enter the command: set
EXTERNAL_POWER_BUTTON_OVERRIDE=disabled .
• Log in to the ILOM CLI, and enter the command start /System .
When the server is powered on to Main power mode and the power-on self-test (POST) code
checkpoint tests are complete, the green System OK LED on the front panel lights and remains
lit to indicate that the system is ready.
