To resolve HWC8010 and UEFI0459 errors, first reseat the PERC 755 RAID card and any associated risers, ensuring they are in the correct slots. Next, access the BIOS/iDRAC settings to accept the current hardware configuration as valid. If the issue persists, check for firmware updates or temporarily remove the PERC card to see if the error clears. [community thread]
The LED codes on the R660 motherboard can signal various issues, such as a 5V switch fault or problems with connected USB devices, iDRAC cables, or the rear I/O card. To troubleshoot, perform a flea power drain, clear the NVRAM, and test with only the minimum components necessary for POST. If the server still does not boot, further inspection of the components may be required. [community thread]

The H755N requires NVMe-specific cables, which are different from those used for SAS PERC cards. Ensure that your server's configuration supports the necessary backplane for the H755N, as it typically accommodates specific drive setups. [community thread]
To address a server that is installed upside down, first remove the side door of the rack to inspect the latch mechanism for any damage or bending.
