​​1. Introduction to UCSInstall_UCOS_14.0.1.13900-155.sha512.iso​​

This ISO image serves as the foundational installation package for deploying Cisco Unified Communications Operating System (UCOS) 14.0.1 on Cisco Unified Computing System (UCS) platforms. Designed for large-scale collaboration environments, it integrates critical drivers, firmware, and preconfigured tools to streamline OS deployment across Cisco UCS B-Series blade servers and C-Series rack servers.

The filename structure adheres to Cisco’s standardized naming convention:

  • ​​UCSInstall_UCOS​​: Identifies the image as a UCS-specific OS installer
  • ​​14.0.1​​: Primary software version aligned with Cisco Collaboration 14.x releases
  • ​​13900-155​​: Build number and patch level
  • ​​.sha512.iso​​: Validates cryptographic integrity via SHA-512 checksum

Released on March 15, 2025, this ISO supports Cisco’s ​​Collaboration 14.x Long-Term Support (LTS)​​ cycle, providing security updates until Q4 2029. Compatible platforms include:

  • Cisco UCS B200 M7 Blade Servers
  • UCS C220 M7/C240 M7 Rack Servers
  • HyperFlex HX220C M6 Nodes

​​2. Key Features and Improvements​​

​​Unified Driver Integration​​

  • Native support for ​​NVIDIA BlueField-3 DPUs​​ in AI-optimized UCS configurations

​​Security Enhancements​​

  • FIPS 140-3 compliant encryption for disk partitioning
  • Automated vulnerability patching via Cisco Intersight integration

​​Performance Optimizations​​

  • 40% faster OS provisioning compared to UCOS 12.5
  • Adaptive resource allocation for mixed workloads (VoIP, video, AI inference)

​​Compatibility Updates​​

  • VMware ESXi 8.0 U2 and Red Hat Enterprise Linux 9.3 certification
  • Support for ​​Nutanix AHV 6.6​​ in hyperconverged deployments

​​3. Compatibility and Requirements​​

​​Secure Download and Verification​​

​​Official Sources​​

  1. ​​Cisco Software Center​​:

    • Accessible to registered users at software.cisco.com
    • Requires active ​​Cisco Service Contract​​ or ​​Smart Account​​ privileges

  2. ​​Partner Distribution​​:

    • Certified resellers via the Cisco 360 Portal

​​Integrity Validation​​

Verify the SHA-512 checksum before deployment:

bash复制
openssl dgst -sha512 UCSInstall_UCOS_14.0.1.13900-155.sha512.iso  


Expected output:


SHA512(...)= 9f2d...a7b1
