Introduction to Bootable_UCSInstall_UCOS_UNRST_15.0.1.10000-32.sha512.iso

This bootable ISO image provides the unrestricted installation package for Cisco Unified Communications Operating System (UCOS) 15.0.1, designed for enterprise-scale collaboration deployments. Released in Q2 2025 under Cisco’s Extended Maintenance Release cycle, it integrates critical security patches identified in 15 CVEs from previous versions while maintaining backward compatibility with 14.x configurations. The SHA512 checksum ensures cryptographic validation compliant with NIST FIPS 180-4 standards, requiring mandatory integrity verification before deployment on UCS C-Series servers or virtualized environments.

The package supports bare-metal installations and VMware ESXi deployments, featuring automated hardware detection for Cisco’s 2025-certified server portfolio. It includes preconfigured drivers for 40GbE/100GbE network adapters and NVMe storage controllers, eliminating manual driver injection during OS deployment.
