5.3 Power On for the First Time

This section provides instructions for each phase of the initial power-on sequence.

5.3.1 Review Safety Guidelines

Before powering on the system or installing any server equipment into the rack, read the Important Safety Information for Oracle's Hardware Systems (7063567) document included with the system.

Before powering on the system, review the following safety precautions. Failure to observe these precautions can result in personal injury, equipment damage, or malfunction.

  • Do not block ventilation openings.

  • Do not place cables under the equipment or stretch the cables too tightly.

  • Do not disconnect power cords from the equipment while its power is on.

  • If you cannot reach the connector lock when disconnecting LAN cables, then press the connector lock with a flathead screwdriver to disconnect the cable. You could damage the system board if you force your fingers into the gap rather than using a flathead screwdriver.

  • Do not place anything on top of the system or perform any work directly above it.

  • Do not let the room temperature rise sharply, especially during winter. Sudden temperature changes can cause condensation to form inside the system. Allow for a sufficient warm-up period prior to system operation.

  • Avoid static electricity at the installation location. Static electricity transferred to the system can cause malfunctions. Static electricity is often generated on carpets.

  • Confirm that the supply voltage and frequency match the electrical ratings indicated on your Oracle Private Cloud Appliance.

  • Do not insert anything into any system opening, unless doing so is part of a documented procedure. The system contains high-voltage parts. If a metal object or other electrically-conductive object enters an opening in the system, then it could cause a short circuit. This could result in personal injury, fire, electric shock, and equipment damage.

5.3.2 Inspect the Appliance

The following procedure describes how to visually inspect your Oracle Private Cloud Appliance after it is physically installed at your site, and prior to power being applied to the system.

  1. Check for rack damage.

  2. Check the rack for loose or missing screws.

  3. Check your Oracle Private Cloud Appliance for the ordered configuration. Refer to the Customer Information Sheet (CIS) on the side of the packaging.

    Note

    Oracle Private Cloud Appliance is preconfigured by Oracle as a self-contained system. You should not move any equipment or add any unsupported hardware to the system.

  4. Check that all cable connections are secure and firmly in place as follows:

    1. Check the power cables. Ensure that the correct connectors have been supplied for the data center facility power source.

    2. Check the network data cables.

  5. Check the site location tile arrangement for cable access and airflow.

  6. Check the data center airflow that leads in to the front of the system.

    For more information, see Section 2.5, “Ventilation and Cooling Requirements”.

5.3.3 Connect the Power Cords

The following procedure describes how to connect power cords to your Oracle Private Cloud Appliance.

  1. Open the rear cabinet door.

  2. Ensure that the correct power connectors have been supplied.

  3. Unfasten the power cord cable ties.

    The ties are for shipping only and are no longer needed.

  5. After powering on the first management node, wait while the second management node and all compute nodes are powered on and discovered.

    Note

    After power is applied, the LEDs on all compute nodes and storage server heads will start to blink after approximately two minutes. From the rear of the rack, you can see the green LEDs on the power supply units (PSUs) on the compute nodes turn on instantly after power is applied. In addition, from the rear of the rack, you can see the display on the power distribution units (PDUs) illuminate once power is available.

    The management nodes will verify all components within the system. The management nodes ensure that the correct networking switches and storage devices are installed in the system, and search for compute nodes to add to the compute fabric. Once compute nodes are located, the management software automatically installs the proper drivers and the Oracle VM Server version on each compute node.

    Depending on your system configuration, the Oracle Private Cloud Appliance power-on process should take approximately five to ten minutes before the system becomes available for initialization, and up to several hours for the entire configuration to be ready. When initialization is completed, use the Oracle Private Cloud Appliance Dashboard web interface to configure initial system settings (for example: network properties and passwords). For instructions on connecting to the Oracle Private Cloud Appliance and accessing the Dashboard UI, see Section 5.3.5, “Connect the Appliance to the Network”.

5.3.5 Connect the Appliance to the Network

For initial access to Oracle Private Cloud Appliance, you must connect a workstation with a monitor to the reserved Ethernet port in the appliance internal management network switch. The Oracle Private Cloud Appliance Dashboard can be reached by means of a web browser.

Note

You can connect the workstation to the Ethernet port at any time during the system power-on process. However, you should wait approximately two to three minutes after starting the power-on process to allow the IP address to become active. If you connect too soon to the port, you will see an HTTP error code 404 or similar code. If this occurs, wait a few minutes and try to connect again.

You can connect your Oracle Private Cloud Appliance to the network as follows:

  1. Ensure that the appliance public interfaces are connected to your data center (public) network.

    For details, refer to Section 3.1.1, “Network Connection Requirements”.

  2. Connect a workstation with a web browser directly to the management network using an Ethernet cable connected to the appropriate port:

    • port 48 in the Cisco Nexus 9348GC-FXP Switch

  3. Configure the wired network connection of the workstation to use the static IP address 192.168.4.254.

  4. Using the web browser on the workstation, connect to the Oracle Private Cloud Appliance Dashboard on the active management node at http://192.168.4.216 .

    192.168.4.216 is the predefined virtual IP address of the management node cluster for configuring Oracle Private Cloud Appliance. If there is another device on your network that is using this IP address, you should change the conflicting device's IP address prior to connecting to the Oracle Private Cloud Appliance.

  5. Log into the Dashboard using the user name admin and the default password, which is provided during the installation process. Contact your Oracle representative if you need the default password.

    Note

    For security reasons, you must set a new password at your earliest convenience.

    When you have logged in to the Dashboard successfully, the home page is displayed. The central part of the page contains Quick Launch buttons that provide direct access to the key functional areas. Click to open the Hardware View.

    The Hardware View indicates the status of the appliance as it is being powered on. All the networking and storage should be green. As the compute nodes are discovered, they will change from yellow to green. Wait until all compute nodes have been discovered and provisioned before making configuration changes in the Dashboard interface.

  6. Using the Dashboard, configure the system environment parameters, including: domain name, NTP and DNS servers.

    Warning

    Before reconfiguring the system network settings, make sure that no provisioning or upgrade processes are running. For details, refer to the section Do Not Reconfigure Network During Compute Node Provisioning or Upgrade within Known Limitations and Workarounds in the Oracle Private Cloud Appliance Release Notes.
