Install the compute-expansion node assembly into the enclosure

Use this procedure to install a compute-expansion node assembly into the enclosure.

Before you install the compute-expansion node assembly into the enclosure:
  1. Read the following section(s) to ensure that you work safely.

  2. Install the PCIe expansion node to the compute node (see Install the PCIe expansion node to a compute node).

Attention
When removing or installing the node assembly, be careful not to damage the node connectors.

Complete the following steps to install the PCIe expansion node assembly into the enclosure.

  1. Select two empty bays vertically adjacent to each other for installation.

    Note

    1. When reinstalling a compute-expansion node assembly removed previously, be sure to install it into the exact same node bays. Some compute node configuration information and update options are established according to node bay number, and reinstalling a compute node into a different node bay can lead to unexpected consequences. If you reinstall the compute-expansion node assembly into different node bays, you might have to reconfigure the installed compute node.

    2. When a compute-expansion node assembly is installed in an enclosure, the other two node bays in the same enclosure must be installed with either one compute-expansion node assembly or two node fillers.

  2. Make sure that the front handles of the compute node are in the fully open position.
  3. Slide the compute-expansion node assembly into the node bays until it stops.
  4. Rotate the compute node handles to the fully closed position with two hands until both the handle latches click into place.
    Note
    The time required for a node to initialize varies by system configuration. 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.
After you install the compute-expansion node assembly to the enclosure, 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 you have other compute nodes to install, do so now.

  4. If this is the initial installation of the node in the enclosure, you must configure the node through the Lenovo XClarity Provisioning Manager and install the node operating system. See OS Installation with Lenovo XClarity Provisioning Manager for more details.

  5. 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 (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).

  6. 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.

  7. If you are installing a different compute node from the one that you removed, update the machine type and serial number with new vital product data (VPD). Use the Lenovo XClarity Provisioning Manager to update the machine type and serial number. See Update the machine type and serial number.

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