This section explains how to replace hardware components in HPE Alletra 4140 nodes.
- We strongly recommend engaging an on-site 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)
- We don’t recommend updating firmware on Qumulo-certified hardware nodes unless the equipment manufacturer or a member of the Qumulo Care team advises you to do so. For questions about this process, contact the Qumulo Care team.
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.
-
Boot by using the latest version of the Qumulo Core USB Drive Installer.
-
Select [*] Perform maintenance.
-
Select [2] 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 1 as you would for a fixable issue to reboot the node and then repeat the part replacement procedure.To Replace a HDD or SSD NVMe Drive
Your HPE Alletra 4140 chassis contains either 60 or 80 HDDs and 8 SSD NVMe drives.
For information about replacing an HDD or SSD NVMe drive, see Storage Drives (HDD and SSD NVMe) in the HPE documentation.
To Replace an M.2 Boot Drive
Your HPE Alletra 4140 chassis contains one NVMe boot drive in an internal M.2 expansion slot.
For information about replacing an M.2 boot drive, see Installing an M.2 Solid State Drive in the HPE documentation.
To Replace a Power Supply Unit (PSU)
Your HPE Alletra 4140 chassis contains two PSUs.
For information about replacing a PSU, see Power Supply in the HPE documentation.
To Replace a Fan
Your HPE Alletra 4140 chassis has six internal fans.
For information about replacing a fan, see System Fans in the HPE documentation.
To Replace a DIMM
Your HPE Alletra 4140 chassis has 24 DIMM slots.
For information about replacing a DIMM, see DIMM Installation in the HPE documentation.
To identify which DIMM failed, you must use the baseboard management controller (BMC) on the node or another hardware monitoring solution.
