This section explains how to replace hardware components in Supermicro 1014S nodes.
- We strongly recommend engaging an on-site Supermicro engineer to replace failed hardware components including but not limited to any procedure that:
- This guide doesn't cover
- You haven't received training on
- Requires precautions to avoid damage caused by electrostatic discharge (ESD) by using industry standard anti-static equipment (such as gloves or wrist straps)
- Don't update your node firmware unless a Qumulo representative instructs you to perform an update.
- Some components vary across node types. For information about node types, see Technical Specifications.
To Perform the Part Replacement Procedure by Using the FVT
When you replace a component such as the motherboard or a NIC card in your node, you must ensure that the firmware version and configuration are correct for your new components. To do this, you must perform the part replacement procedure by using the FVT.
Before you replace the motherboard, you must request a new Data Center Management Suite (DCMS) license key from Supermicro and apply it before you run the FVT. (The license key uses the BMC MAC address which changes with the motherboard.) If you don’t install a DCMS license on your node, the Field Verification Tool (FVT) fails, preventing you from running the part replacement procedure in the FVT, which normalizes the firmware and BIOS configuration for your new motherboard.
Boot by using the latest version of the Qumulo Core USB Drive Installer.
Select [*] Perform maintenance.
Select  Perform automatic repair after part replacement (non-destructive).
The part replacement procedure runs and the FVT passed! message appears.
In some cases, after the part replacement procedure, the message
FIX: Run the FVT flash command.appears. Enter
1as you would for a fixable issue to reboot the node and then repeat the part replacement procedure.
To Replace a Drive
Your Supermicro 1014S chassis contains 12 HDDs, 4 NVMe drives, and one NVMe boot drive (in an internal M.2 expansion slot). For information about replacing a drive, see Drive Bay Mapping and the following topics in the Supermicro documentation.
To Replace a Power Supply Unit (PSU)
Your Supermicro 1014S chassis contains two PSUs. For information about replacing a PSU, see Power Supply in the Supermicro documentation.
To Replace a Fan
Your Supermicro 1014S chassis has six internal fans. For information about replacing a fan, see System Fans in the Supermicro documentation.
To Replace a DIMM
Your Supermicro 1014S chassis has 16 DIMM slots. For information about replacing a DIMM, see DIMM Installation and DIMM Module Population in the Supermicro documentation.
To identify which DIMM failed, you must use the baseboard management controller (BMC) on the node or another hardware monitoring solution.
