خوب طبیعی هستش که وقتی کابل مربوطه رو قطع مکنید ارتباط قطع میشه و باید هم BUSF روشن بشه اما اگه OBهای مربوطه باشه STOP نمیشه

ممنون ولی در Hwconfig هیچ وسیله ای برای پروفیباس تعریف نشده در این شرایط CPU ران هست ولی BUSF ثابت روشنه وقتی یک کانکتور 9 پین به پورت وصل می کنم باس فالت خاموش میشه

سلام وقت بخیر

این مورد نشان دهنده آسیب سخت افزاری به پورت DP روی CPU است که معمولاً بر اثر ارت نامناسب یا عدم وجود آن و وجود ولتاژ روی بدنه رک رخ داده است.

در این شرایط ولتاژی بر روی پورت DP منعکس می شود که با وجود Terminator روی کانکتور شبکه، این ولتاژ مصرف و حذف می شود در نتیجه "BUSF" خاموش می شود.

البته در برخی شرایط امکان استفاده از پورت DP همچنان وجود دارد و در حالتی دیگر ممکن است ارتباط برقرار نشود و نیاز به تعمیر دارد.

موفق باشید
