ZyXEL GS-105B V2 有尖銳高頻音

Jan 20th 2015, 14:41

最近買了一台ZyXEL GS-105B V2 switch

發現接上NB和數據機都會出現微小的高頻音, 耳朵離30cm才能明顯聽到

實驗1: switch 只接電源, 無聲音
實驗2: switch 接電源+NB, 開始有較低頻的聲音出現
實驗3: switch 接電源+數據機, 聲音和實驗2相同
實驗4: switch 接電源+NB+數據機, 開始有"較高頻"的聲音出現, 而且聲音會隨著燈號亮滅而斷斷續續

雖然把switch離開耳朵1公尺以上, 高頻會比較聽不見, 但是就是覺得很煩

請問大家有類似的經驗嗎？
