For a Rated-3 data center, network architecture is indeed a key component of the audit under

ANSI/TIA-942. This rating requires concurrent maintainability across all systems, including

telecommunications infrastructure. The network architecture must therefore meet specific

redundancy and reliability standards to ensure uninterrupted operations during maintenance or

failure of any single component.

Detailed Explanation:

Rated-3 requirements extend beyond electrical and mechanical systems to include network

architecture. This ensures that telecommunications systems are also designed for concurrent

maintainability, thus contributing to overall uptime and resilience.

EPI Data Center Specialist Reference:

EPI endorses comprehensive assessments for Rated-3 facilities, emphasizing that network systems

must meet standards for redundancy and concurrent maintainability, which align with ANSI/TIA-

942’s holistic approach to data center reliability.
