Yes, the SR650 v3 server supports various configurations for front drive bays, including NVMe backpanels. Ensure that the RAID card and NVMe cables are properly configured with the new disk panel. [community thread]
If the remote video via Xclarity is not showing the login screen, first ensure that you are using the latest firmware for the XCC2. If the issue continues, try accessing the XCC2 from a different computer, restarting the XCC2, or performing an AC cycle by unplugging the server. If none of these steps resolve the issue, consider reapplying or updating the XCC2 firmware. [community thread]
The installation may be failing due to an incorrect driver being loaded for the RAID controller. Ensure you download the appropriate driver for Windows Server 2022 from the Lenovo support site, and verify that your UEFI, XCC, and LXPM firmware are updated to the latest versions. After updating, reboot the server and attempt the installation again. [community thread]
