Replacing the failed chassis

After you remove the failed node from the cluster, you can remove the failed chassis, and install the replacement chassis.

Before you begin

  • You have an electrostatic discharge (ESD) wristband, or you have taken other antistatic protection.
  • You have the replacement chassis.

Steps

  1. Put on antistatic protection.
  2. Unpack the new chassis, and set it on a level surface.
    Keep the packaging material for when you return the failed chassis to NetApp.
  3. Label each cable that is inserted at the back of the chassis that you are going to remove.
    After you install the new chassis, you must insert the cables back into the original ports.

    The following figure shows the cabling of an H610C compute node:
    This figure shows the cabling of an H610C compute node.

    Port Details

    Ports C and D

    Connect the node to a 10/25GbE network using two SFP28/SFP+ cables.

    IPMI

    Connect the node to a 1GbE network using an RJ45 connector.
    Connect both power cables to the node.

    The following figure shows the cabling of an H615C compute node:
    This figure shows the cabling of an H615C compute node.

    Port Details

    Ports A and B

    Connect the node to a 10/25GbE network using two SFP28/SFP+ cables.

    IPMI

    Connect the node to a 1GbE network using an RJ45 connector.
    Connect both power cables to the node.
  4. Disconnect all the cables from the back of the chassis.
  5. Remove the chassis by unscrewing the thumbscrews on the mounting ears.
    You must package and return the failed chassis to NetApp.
  6. Only for H615C. Remove the DIMMs from the chassis. You will insert these DIMMs in the replacement chassis.
  7. Remove the two power supply units on either side of the chassis.
    You can use these power supply units in the new chassis.
  8. Optional: Remove the rails and install the new rails that were shipped with your replacement chassis.
    If you choose to reuse the existing rails, you can skip this step.
  9. Slide the replacement chassis on to the rails.
    Attention: Ensure that you do not use excessive force when sliding the chassis on to the rails.
  10. Place the chassis that you removed on a level surface.
    You must package it and return it to NetApp.
  11. Replace the power supply units.
  12. Only for H615C. Insert the DIMMs that you removed from the failed chassis, and insert them in the replacement chassis.
  13. Reconnect the cables to the ports from which you originally disconnected them.
    The labels you had on the cables when you disconnected them will help guide you.
    Attention:
    • If the airflow vents at the rear of the chassis are blocked by cables or labels, it can lead to premature component failures due to overheating.
    • Do not force the cables into the ports; you might damage the cables, ports, or both.
  14. Power on the chassis.

After you finish

After you replace the failed chassis, you must install VMware ESXi and the NVIDIA vGPU driver, and add the node to an existing cluster.
