Introduction to UCSInstall_CER_14.0.1.13900-34.sha512.iso

This SHA512-verified ISO package delivers the complete firmware suite for Cisco Unified Computing System (UCS) Collaboration deployments running Release 14.0.1 Extended Stable Release (ESR). Officially released on April 28, 2025, it consolidates 34 critical updates for Cisco UCS B-Series Blade Servers and C-Series Rack Servers participating in collaboration workloads like Webex Calling and Unified Communications Manager.

The bundle complies with FIPS 140-3 cryptographic standards and addresses 17 Common Vulnerabilities and Exposures (CVEs) identified in previous firmware versions. It supports hybrid cloud deployments through Cisco Intersight integration and maintains backward compatibility with UCS Manager 4.0(4d) configurations.
