text: <s>[INST] PF70ec DPI Comm loss fault 85 I have 8 Pf70ec drives connnected with 20-comm-e cards and one of the drives gives random a comm loss fault 85. Only one of the drives ever does this and it hasn't happened for about 2 months until today when it happened twice. All of the post I have read say this is uncommon for the comm-e card. So any suggestions would be great. [/INST] Try to take a look to this thread .... the problem could also happen on an Ethernet comm card, as this fault indicates that the main control board has lost communications with the 20-COMM-x... there are detailed explanations by Ken Roach about this fault. - fuzzy logic \\n </s>
