Introduction to UCSInstall_UCOS_15.0.1.10000-32.sha512.iso

This SHA512-verified bootable ISO provides the foundational operating system for deploying Cisco Unified Communications Manager (CUCM) 15.0.1 clusters on UCS C-Series servers. Designed for large-scale collaboration environments, it integrates FIPS 140-3 Level 1 validated cryptographic modules and RFC 9421-compliant data validation protocols, ensuring secure initialization of voice/video collaboration infrastructures.

The “UCOS” designation confirms implementation of Cisco’s hardened real-time kernel optimized for 3rd Gen Intel Xeon Scalable processors, supporting deterministic task scheduling with <5μs latency for SIP packet processing. This release specifically targets enterprises requiring FedRAMP Moderate compliance in healthcare and financial sectors.
