Introduction to UCSInstall_UCOS_14.0.1.12900-161.sha512.iso

The ​​UCSInstall_UCOS_14.0.1.12900-161.sha512.iso​​ is the official bootable installation image for Cisco Unified Communications Operating System (UCOS) version 14.0.1.12900-161, released on ​​April 28, 2025​​ as part of Cisco’s Q2 2025 software refresh cycle. This ISO file serves as the foundation for deploying Cisco Collaboration Suite components including Unified Communications Manager (CUCM), Unity Connection, and IM&P services in enterprise environments.

Designed for bare-metal installations on Cisco UCS C-Series rack servers, the image integrates SHA-512 checksum validation (FIPS 180-4 compliant) to ensure cryptographic integrity during deployment. It supports hybrid cloud implementations through native integration with VMware ESXi 8.0U2 and Cisco HyperFlex 5.0 platforms.
