Power On the Modular System for the First Time

  1. Ensure that you performed the tasks listed in Prepare the Modular System for Power.
  2. Read and follow the information in ESD and Safety Precautions.
  3. Ensure that the modular system power cables are plugged into an acceptable outlet.

    See Connect the Modular System Cables.

  4. Perform one of the following at the electrical circuit breakers for main power, based on the PDU type.
    • For systems with 22 kVA PDUs (six cables):
      1. Turn on the circuit breakers to the cables labeled PDU B Input 1 and PDU A Input 1.
      2. Verify that the System Status LEDs light.
      3. Turn on the circuit breakers to the other four cables.
    • For systems with 24 kVA PDUs (four cables):
      1. Turn on the circuit breakers to the cables labeled PDU B Input 1 and PDU A Input 0.
      2. Verify that the System Status LEDs light.
      3. Turn on the circuit breakers to the other two cables.

    For general information on PDUs, refer to the Sun Rack II Power Distribution Units User’s Guide.

  5. Verify that the modular system is powered on and the configuration is valid.

    The amber Fail LED on the front panel will turn off and stay off. If the Fail LED is on, configuration errors have occurred. For a description of each system LED, see Modular System Status LEDs. If the OK status LED is not solid green, see Troubleshooting Installation Issues.

  6. Verify that every node comes online.

    The compute node's green OK LED begins to flash to indicate that the node was discovered and the power-up sequence has started. The node's OK LED then turns solid green. For a description of each node LED, see Node Status LEDs. For more information about interpreting diagnostic LEDs, refer to the product-specific documentation.

    When you add a compute node, the NET MGT compute node port is automatically configured. The solid green OK LED indicates that the compute node is initialized and ready for operation.


    Tip  -  After a compute node with a preinstalled OS is online, you can automatically power on the compute node through the modular system's management software, based on the hot-swap policy. The hot-swap policy default is to allow the compute node to activate, deactivate, and power on. For more information, refer to Modifying the Service Processor Network Settings Using Oracle ILOM in Oracle Server X5-2 Installation Guide or Oracle Server X6-2 Service Manual.

    If all compute nodes do not come online, see Troubleshooting Installation Issues.

  7. (Optional) Power balance the modular system.

    See 3-Phase Power Balancing.

    If you want to install nodes at a later time, refer to the Netra Modular System Service Manual Supplement.

  8. (Optional) Install an OS and other applications on the node.

    Follow the instructions in Install an OS (Oracle System Assistant).
