Install a compute node in the enclosure

Use this information to install a compute node in the DA240 Enclosure.

About this task

To avoid possible danger, read and follow the following safety statement.
  • S002
    disconnect all power
    CAUTION:
    The power-control button on the device and the power switch on the power supply do not turn off the electrical current supplied to the device. The device also might have more than one power cord. To remove all electrical current from the device, ensure that all power cords are disconnected from the power source.
Attention:
  • Read the Installation guidelines to ensure that you work safely.
  • Be careful when you are removing or installing the compute node to avoid damaging the node connector(s).
Watch the procedure. A video of the installation process is available:

Procedure

Figure 1. Compute node installation
Compute node installation

  1. Install a compute node in the enclosure.
    1. Make sure that the front handle on the compute node is in the fully open position; then, slide the compute node into the node bay until it stops.
    2. Rotate the front handle to the fully closed position until the handle latch clicks.
    Attention:
    • If you are reinstalling a compute node that you removed, you must install it in the same node bay from which you removed it. Certain configuration information and update options are established based on respective node bay numbers. Reinstalling a compute node into a different node bay could lead to unintended consequences. If you reinstall the compute node into a different node bay, you might have to reconfigure the compute node.

    • The time required for a compute node to initialize varies by system configurations. The power LED flashes rapidly; the power button on the compute node will not respond until the power LED flashes slowly, indicating that the initialization process is complete.

    • To maintain proper system cooling, do not operate the DA240 Enclosure without a compute node or node bay filler installed in each node bay.

  2. If you have other compute nodes to install, do so now.

After you finish

After you install a compute node, complete the following steps:
  1. Check the power LED to make sure it transitions between fast blink and slow blink to indicate the node is ready to be powered on; then, power on the node.

  2. Make sure that the power LED on the compute node control panel is lit continuously, indicating that the compute node is receiving power and is turned on.

  3. If this is the initial installation of the node in the enclosure, you must configure the node through the Lenovo XClarity Provisioning Manager V3 and install the node operating system. See Deploy an operating system through XClarity Provisioning Manager V3 for more details.

  4. If compute node access over local console is not available:

    1. Access Lenovo XClarity Controller web interface (see Accessing the XClarity Controller web interface).

    2. Set up Lenovo XClarity Controller network connection through Lenovo XClarity Provisioning Manager V3 (see Setting up the XClarity Controller network connection through the XClarity Provisioning Manager).

    3. Log in to Lenovo XClarity Controller (see Logging in to the XClarity Controller).

  5. If you have changed the configuration of the compute node or if you are installing a different compute node from the one that you removed, you must configure the compute node through the Setup utility, and you might have to install the compute node operating system, see System configuration for more details.

  6. You can place identifying information on the pull out label tab that are accessible from the front of the node.
