سلام دوستان. دو cpu400H که بصورت ریدیندانت است و دوتا et200m که بخواهیم با فیبر نوری وصل بشویم داریم. توپولوژی استفاده از OLM به چه صورت است؟ دوتاolm p11 در کنار cpu و دوتا olm p12 در آخر یا 4 عدد olm p11 کافی است؟

سلام وقت بخیر

اگر بخواهید از توپولوژی Redundant Daisy Chain استفاده کنید، می توانید ابتدا و انتهای باس هر کدام دو OLM P11 قرار داده و وسط باس OLM P12 باشد و اگر بخواهید از توپولوژی Ring استفاده کنید، باید تمام OLM ها از نوع P12 باشند.
