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.

Before mounting the ISO, always verify the MD5 or SHA512 checksum. Corrupt downloads are the leading cause of "Media Not Found" errors during the UCOS installation phase. 2. CIMC Virtual Media On Cisco UCS C-Series servers, use the CIMC to map the ISO: Log into the . Open the Launch KVM Console . Version 8

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

If you see this error despite using the patched ISO, check your settings. Cisco UC applications are very sensitive to the RAM and CPU reservations defined in VMware. Ensure you are using the exact "Virtual Machine Template" (OVA) specified for version 8.6(2). Important Security Note

Refers to the underlying TiVo-like Linux distribution Cisco uses for applications like CUCM (CallManager), Unity Connection, and CUPS.
