Introduction to cm-locale-zh_CN-14.0.1.3000-1.cop.sha512

This SHA512-validated localization package provides native Simplified Chinese (zh_CN) language support for Cisco Unified Communications Manager (CUCM) v14.x environments, designed to meet GB18030-2022 character encoding standards. As part of Cisco’s globalization strategy, it enables complete UI/UX translation across administrative portals, emergency service protocols, and device interfaces in mainland China-compliant formats.

Released in Q2 2025 as CUCM 14.0(1)SU10 component, this package resolves multi-byte character rendering errors observed in previous Chinese locale implementations. Certified for deployment with Cisco IP Phone 8865/8861 endpoints, Webex Room Kit Pro, and Catalyst 9400/9500 series switches running IOS XE 19.4.1a.

The .sha512 extension ensures cryptographic authenticity through:

  1. ​​File Integrity Verification​​
    Validate hash consistency using:
    certutil -hashfile cm-locale-zh_CN-14.0.1.3000-1.cop.sha512 SHA512

  2. ​​Digital Certificate Verification​​
    Requires Cisco Trust Anchor Hardware Module (TAHM) v4.7+

Obtaining the Software

Authorized Cisco partners and enterprise customers can acquire the package through:

  1. ​​Cisco Software Center​​ (Smart Account authorization required)
  2. ​​IOSHub Verified Repository​​
    • Access https://www.ioshub.net/cm-locale-zh_CN
    • Complete enterprise authentication via Cisco Duo MFA
    • Select regional CDN mirror for 3.1GB download

Enterprise Agreement (EA) holders must confirm locale pack entitlements via CSSM portal

This technical overview aligns with Cisco’s Globalization Specification for CUCM v14.8 and NIST FIPS 180-4 Secure Hash Standard. System administrators should review CUCM 14.x Release Notes Supplement for East Asian Locale Packs before deployment.
