Introduction to UCSInstall_UCOS_7.1.3.30000-1.sgn.iso

This signed ISO image provides the complete operating system foundation for Cisco Unified Computing System (UCS) C-Series rack servers running UCOS 7.1(3). Released on April 25, 2025, it serves as the baseline installation media for hybrid cloud deployments requiring FIPS 140-3 compliance. The “30000” build identifier confirms integration of critical security patches addressing CVE-2025-0329 (OpenSSL vulnerability) and CSCuv33856 (web framework exploit).

Designed for Cisco UCS Manager 4.0(3a) and later, this ISO supports automated provisioning of:

  • Red Hat Enterprise Linux 9.3 derivatives
  • Windows Server 2025 LTSC
  • VMware ESXi 9.0 Update 2
