Introduction to UCSInstall_UCOS_8.0.2.20000-8.sgn.iso

This cryptographically signed ISO provides the complete deployment package for Cisco Unified Communications Manager (CUCM) 8.0(2)SU8, specifically optimized for VMware vSphere 7.0U3+ and Cisco UCS C-Series rack servers. The “.sgn” extension confirms Secure Boot validation through Cisco’s Trust Anchor 4.0 technology, meeting FIPS 140-2 Level 3 compliance standards for government-grade deployments. Designed for multi-site enterprise collaboration environments, it integrates preconfigured templates supporting 1,000-50,000 user clusters.
