Returning the Server to Operation

This section describes safety considerations and provides procedures and information after replacing components in the server.

After replacing components inside of the server, perform the procedures in the following sections. For more information, see the component replacement procedures in this guide.

Reconnect Cables

Reconnect the power cables to the power supplies at the back of the server, and secure them from accidental disconnection with the securing straps.

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.
