1. Introduction to UCSInstall_CCP_12_5_1_UCOS_12.5.1.11003-470.sgn.iso

The ​​UCSInstall_CCP_12_5_1_UCOS_12.5.1.11003-470.sgn.iso​​ is Cisco’s comprehensive deployment package for Unified Computing System (UCS) infrastructure, integrating Compute Cluster Platform (CCP) management with Unified Communications Operating System (UCOS) 12.5.1. Released in Q1 2025, this signed ISO image enables automated deployment of converged infrastructure supporting up to 500 physical servers in hyperconverged environments.

Designed for Cisco UCS C880/C890 Series and B-Series Blade Servers, the package combines firmware bundles for fabric interconnects, I/O modules, and server nodes with preconfigured UCOS templates. Its dual-stack IPv4/IPv6 architecture supports hybrid cloud deployments through Cisco Intersight integration.
