5. If you want to reuse the DIMMs, remove them.
6. Pull down the cam handle on the right side of the node, and pull the node out using both the cam handles.
The cam handle that you should pull down has an arrow on it to indicate the direction in which it moves.
The other cam handle does not move and is there to help you pull the node out.

Support the node with both your hands when you pull it out of the chassis.
7. Place the node on a level surface.
You should package the node and return it to NetApp.
8. Install the replacement node.
9. Push the node in until you hear a click.

Ensure that you do not use excessive force when sliding the node into the chassis.

Ensure that the node powers on. If it does not power on automatically, push the power
button at the front of the node.
10. If you removed DIMMs from the failed node earlier, insert them into the replacement node.

You should replace DIMMs in the same slots they were removed from in the failed node.
11. Reconnect the cables to the ports from which you originally disconnected them.
The labels you had attached to the cables when you disconnected them help guide you.

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.

Ensure that the replacement node is cabled in the same way as the other nodes in the
chassis.
Remove the compute node asset in NetApp HCI 1.7 and later
In NetApp HCI 1.7 and later, after you physically replace the node, you should remove the compute node asset
using the management node APIs. To use REST APIs, your storage cluster must be running NetApp Element
software 11.5 or later and you should have deployed a management node running version 11.5 or later.
Steps
1. Enter the management node IP address followed by /mnode:
https://[IP address]/mnode
2. Select Authorize or any lock icon and enter cluster admin credentials for permissions to use APIs.
a. Enter the cluster user name and password.
b. Select Request body from the type drop-down list if the value is not already selected.
c. Enter the client ID as mnode-client if the value is not already populated.
Do not enter a value for the client secret.
d. Select Authorize to begin a session.
