Replace Dimms In Compute Nodes - NetApp HCI Manual

5. Power on the DC power supply units.

The power supply LEDs are lit when the DC power supply unit comes online. Green LED
lights indicate that the power supply units are working correctly.
6. Return the faulty unit to NetApp by following the instructions in the box that was shipped to you.

Replace DIMMs in compute nodes

You can replace a faulty dual inline memory module (DIMM) in NetApp HCI compute
nodes instead of replacing the entire node.
What you'll need
• Before starting this procedure, you should have contacted NetApp Support and received a replacement
part. Support will be involved during the installation of the replacement. If you have not done so already,
contact Support.
• You have planned for system downtime, because you need to power down or cycle the node and boot the
node to NetApp Safe Mode to access the terminal user interface (TUI).
About this task
This procedure applies to the following compute node models:
• H410C nodes. An H410C node is inserted into a 2U NetApp HCI chassis.
• H610C node. An H610C node is built into the chassis.
• H615C node. An H615C node is built into the chassis.

H410C and H615C nodes include DIMMs from different vendors. Ensure that you do not
mix DIMMs from different vendors in one chassis.
