When auditors arrive, they will check three things:
: The standard now explicitly requires a minimum of two Category 6A or higher balanced twisted-pair cables to power and backhaul modern high-throughput wireless access points within the facility [1.19]. Environmental Controls, Power, and Sustainability Most data centers are (concurrently maintainable)

As a final note, the table below provides a quick reference guide to the certification process. It summarizes the three certification types, their audit scope, and the validity period of each. their audit scope
：在MDA（主配线区）、IDA（中间配线区）、HDA（水平配线区）等关键布线节点，机柜最小宽度提升至800mm（约31.5英寸），以容纳高密度光缆及连接器。对比传统24英寸机柜已不再适配现代高密度布线，800mm机柜更能满足AI、高性能计算所需的光纤密度要求；
