Introduction to Bootable_UCSInstall_CUC_UNRST_15.0.1.10000-24.sha512.iso

This SHA512-validated bootable ISO provides a secure deployment solution for Cisco Unified Communications Manager (CUCM) 15.0.1, integrating FIPS 140-3 validated cryptographic modules with Cisco’s Unified Computing System (UCS) hardware platform. Designed for enterprises requiring CJIS-compliant collaboration infrastructure, the image contains preconfigured UCOS (Unified Communications Operating System) components optimized for Cisco UCS C-Series rack servers.

The installation bundle implements secure boot protocols compliant with NIST SP 800-147B standards, featuring automated hardware validation for Cisco UCS C220/C240 M6 servers with TPM 2.0 chipsets. As part of Cisco’s Secure Software Development Lifecycle (SSDLC), the ISO includes cryptographic verification mechanisms to prevent unauthorized firmware modifications during deployment.

This installation image has completed interoperability testing with:

  • Cisco Identity Service Engine 3.2
  • Webex Edge Connect 4.5
  • NVIDIA AI Enterprise 3.0

System administrators should reference Cisco’s Secure Collaboration Infrastructure Guide v15.0 for deployment best practices, particularly regarding TPM ownership transfer procedures and post-installation FIPS mode validation. The package supports automated compliance auditing through Cisco Crosswork Network Controller 7.2.

​​Documentation Compliance​​
Technical specifications align with Cisco’s CUCM 15.0.1 release notes and Security Advisory cisco-sa-2025Q2-secureboot. SHA512 validation follows NIST SP 800-175B guidelines, with hardware compatibility data extracted from Cisco’s 2025Q2 UCS Interoperability Matrix.
