Hi 2ndSource.   The latest iDRAC firmware for R620 is 2.65.65.65. As it seems you have a very old firmware, so I recommend performing staged updates (like 1.66.65 -> 2.10.10.10 -> 2.30.30.30 -> 2.65.65.65).   Regarding the Lifecycle Controller, you first should update it to the latest version when it was separated from iDRAC.Here's the link: [URL]   OR   You decide for the platform-specific bootable ISO: [URL]   with this ISO you update all components at once. For more guidance check out the related article Update PowerEdge Servers with Platform Specific Bootable ISO (SLN296511).   Let me know if this solved the issue.   Best regards,Stefan
