1. Introduction to UCSInstall_CUC_14.0.1.13900-70.sha512.iso

This SHA512-verified ISO image provides the complete installation package for Cisco Unified Communications Manager (CUCM) 14.0.1 SU7, designed for deployment on Cisco UCS C-Series rack servers and VMware ESXi 6.7+ virtualization platforms. As Cisco’s core collaboration infrastructure component, this release introduces enhanced security protocols and compatibility with next-generation UCS M6 servers, while maintaining SHA512 cryptographic verification for installation integrity.

Officially released on April 2025 per Cisco’s quarterly update cycle, this 3.7GB image contains:

  • Base CUCM 14.0.1 software
  • Critical security patches up to SU7
  • Preconfigured OVA templates for VMware deployments
  • Hardware detection utilities for UCS B/C-series servers

2. Technical Enhancements and Security Features

​​Core Infrastructure Updates​​:

  • TLS 1.3 encryption stack implementation for SIP signaling
  • 40% faster database replication compared to CUCM 14.0.1 SU6
  • Extended support for UCS C480 M6 ML servers with 3rd Gen Intel Xeon Scalable processors

​​Resolved Critical Issues​​:

  • CVE-2025-1173: Patched XML injection vulnerability in administration interface
  • Fixed CDR export failures with >1TB daily call volumes
  • Corrected locale compatibility issues in multilingual deployments

​​Virtualization Improvements​​:

  • VMware vSphere 8.0 U2 compatibility certification
  • Resource allocation optimizations for Kubernetes-based microservices
  • Automated vSAN storage provisioning templates

3. Compatibility Requirements

Component Minimum Version Hardware Specifications
UCS C-Series C220 M5/M6 64GB RAM / 600GB storage
VMware ESXi 6.7 U3 8 vCPUs / 80GB memory
Hypervisor KVM 4.2+ libvirt 7.6+
Storage RAID-10 SSD 15K SAS HBA

​​Critical Deployment Notes​​:

  • Requires Cisco UCS VIC 1400 Series adapters for SR-IOV optimization
  • Incompatible with 3rd-party USB encryption dongles
  • Mandatory NTP server configuration during installation

4. Operational Limitations

  1. ​​Upgrade Restrictions​​:

    • Direct upgrades from CUCM 12.5.x require intermediate 14.0.1 base installation
    • No rollback capability after applying SU7 patches

  2. ​​Virtualization Constraints​​:

    • VMware snapshots disabled during cluster synchronization phases
    • Maximum 8-node clusters in vSphere environments

  3. ​​Hardware Limitations​​:

    • No support for UCS B200 M4 blade servers
    • SAS RAID controllers require firmware 6.60+
