1364.0. "90C and CRC errors" by HITEKS::PEER () Wed Aug 31 1994 09:46

    Could someone please validate, clarify or give me someone that I may
    speak with in reference to this. I have been told that there is a
    potential problem with the retiming on the 90C module. Specifically
    that if I have the 90C attached to a segment or segments which use
    large packet sizes and vendor NIC cards in the PCs, that I may
    experience CRC and framing errors on those segments. It was also
    explained to me that there may be a list of vendor NIC cards that could
    be suspect. I have a customer which is using mostly MAC's and I have
    been logging both CRC and framing errors on those segments. I have
    tested the segments with a TDR and monitored them with a Sniffer. The
    TDR test helped me eliminate some bad cabling but after that I'm still
    logging errors. 
    
    As this is a new installation for NIS, I need to figure out what my
    next step is going to be. Any help with this 90C issue would be greatly
    appreciated. 
    
    Regards,
    
    Regina
