1. Introduction to PCD_UCOS_14.0.1.11900-136.sha512.iso
This cryptographically verified operating system image provides core platform services for Cisco Unified Communications Manager (CUCM) 14.0(1)SU9 deployments. Designed for enterprises requiring ISO/IEC 27001:2025-compliant infrastructure, it implements secure firmware updates while maintaining backward compatibility with legacy SIP devices.
The 14.0.1.11900-136 build introduces SHA-512 hashing for firmware integrity verification and optimizes memory allocation for HyperFlex HX280c clusters. Compatible with CUCM clusters running 14.0(1)SU7 or later, it supports hybrid environments spanning Cisco UCS C480 M7 servers and Intersight managed infrastructure.
2. Key Features and Improvements
