To resolve firmware upgrade issues, consider performing a staged upgrade by first updating to version 22.5.x before moving to 23.0.x. Additionally, try running the updates from a Live ISO environment and ensure that the BIOS and iDRAC versions are consistent across all systems. [community thread]
To upgrade the C6400 to an NVMe backplane, you will need the NVMe backplane itself and specific backplane cables. Note that the C6400 can only support 8 NVMe drives, and if you have a PERC H330 or H730 installed in the C6420 nodes, you will need to replace them with a PERC S140 or HBA330, as the former do not support NVMe.

Ensure that the server's BIOS, iDrac, and H730 RAID controller firmware are all updated to the latest versions, as outdated components may interfere with the SSD firmware update process. If the issue persists, consider reaching out to support for further assistance. [community thread]
Ensure that the TPM module is compatible and has not been previously installed on another server, as it is cryptographically bound to the original system board. Check that the BIOS is updated and configured for UEFI boot mode. If issues persist, consider verifying the mainboard part number and the TPM part number without the leading zero. [community thread]
If you're experiencing no video from the mini DisplayPort, ensure you are using a compatible adapter, as some may only support analog output. It's recommended to try a mini DisplayPort to VGA adapter, as this has been noted to work with certain configurations. [community thread]
