If you are deploying this specific build, follow these steps to ensure a successful boot: 1. MD5 Verification

Ensures the ISO is correctly seen as a bootable device by the UCS BIOS or CIMC (Cisco Integrated Management Controller). Installation Best Practices

The specific version branch and build number.

Version 8.6(2) is significantly past its End-of-Software-Maintenance (EoSM) date. While the patched ISO makes installation possible on newer hardware, it does not address the modern security vulnerabilities present in such an old kernel. This version should ideally be used only for lab environments or as a stepping stone in a multi-stage upgrade path to a supported version like CUCM 12.5 or 14/15.

Indicates the file is cryptographically signed by Cisco for security. Why the "Patched" Version is Required

Under the tab, select Add Image and map your patched ISO. Ensure the "Mapped" checkbox is selected. 3. BIOS Boot Order

Ensure the server is set to boot from "Cisco vMedia" or "EFI DVD/CD" as the first priority. Because this is an older 8.6(2) based build, you may need to ensure your UCS Boot Policy is set to mode rather than UEFI , as older UCOS versions do not consistently support UEFI boot.

If you are working with legacy Cisco Unified Computing System (UCS) hardware or specific Unified Communications (UC) applications, you may have encountered the requirement for a specific bootable image: (often referred by its shorthand build number 8621000014sgn161 ).

Indicates this is a bootable installer designed for Cisco UCS platforms.
