The RS (Radiated Immunity) test for data center switches is conducted according to the IEC 61000-4-3 standard, applicable to frequencies from 80MHz to 6GHz. General industrial environments require a field strength of 3V/m (Level 2), power and outdoor scenarios require 10V/m (Level 3), and harsh military environments require 30V/m (Level X). Typical data center scenarios fall into Levels 2-3, with a design target of 10V/m and a 6dB margin (20V/m). Audiotech's solution includes: chassis shielding effectiveness >30dB@1GHz; interface filtering using CMZ2012A-900T common-mode inductors; grounding of critical PCB signals; and the addition of a PBZ1005B-102Z0T (1000Ω@100MHz) ferrite bead to the reset line. Actual measurements show zero system crashes and zero throughput loss at a field strength of 10V/m.
