Remove a compute node from the enclosure

Use this procedure to remove a compute node from the D2 Enclosure.

Attention:
  1. Unauthorized personnel should not remove or install the nodes. Only trained or service-related personnel are allowed to perform such actions.

  2. If one or more sets of shared PCIe dual adapters are installed in the enclosure, make sure to remove the nodes with auxiliary adapters first (node 2 and 3) and proceed to nodes with primary adapters (node 1 and 4). See the following table for location of primary and auxiliary adapters.

Before you remove a compute node:

  1. Read the following section(s) to ensure that you work safely.
  2. Turn off the corresponding compute node that you are going to perform the task on.

  3. When you remove the compute node, note the node bay number. Reinstalling a compute node into a different node bay from the one it was removed from can have unintended consequences. Some configuration information and update options are established according to node bay number. If you reinstall the compute node into a different node bay, you might have to reconfigure the compute node. One way to track node is via the serial number.
    Note: The serial number is located on the pull out tab for the each node.

Complete the following steps to remove the compute node from a enclosure.

Watch the procedure. A video of the installation process is available:

  1. Release and rotate the front handle as shown in the illustration.
    Attention: To maintain proper system cooling, do not operate the D2 Enclosure without a compute node or node bay filler installed in each node bay.
  2. Slide the node out about 12 inches (300 mm); then, grip the node with both hands and remove it from the enclosure.
  3. Install either a node bay filler or another compute node in the node bay within 1 minute.

If you are instructed to return the component or optional device, follow all packaging instructions, and use any packaging materials for shipping that are supplied to you.
