The recommended maximum voltage level for Common Mode Noise (CMN) is typically around 3V according to equipment vendors. This level is considered optimal as it helps in maintaining the integrity of data transmission while minimizing the risk of interference and potential damage to sensitive components. Keeping the voltage level at or below this threshold ensures that the equipment operates within safe parameters, which is crucial for the reliability and longevity of electronic devices used in data center environments.

As voltage levels rise above this threshold, the likelihood of degrading signal quality increases, leading to errors and malfunctions in electronic systems. This understanding is critical for professionals involved in designing and maintaining data centers, as managing noise and ensuring optimal performance directly impacts overall system reliability.
