1. Introduction to UCSInstall_CUC_14.0.1.11900-128.sha512.iso
This enterprise-grade installation image provides the complete deployment package for Cisco Unified Communications Manager (CUCM) 14.0.1, featuring SHA512 cryptographic verification for secure distribution. Designed for ESXi 7.0+ and KVM virtualization environments, it integrates Cisco’s Unified Computing System (UCS) hardware validation routines to ensure compatibility with B/C-Series servers.
Released through Cisco’s authorized channels on April 28, 2025, this version introduces automated driver injection for 40G/100G VIC adapters and prevalidates NFSv4.1 storage configurations. The ISO contains localized components for 28 languages while maintaining FIPS 140-3 compliance for government deployments.
