One AS500/500 has been causing network errors. It looks like the internal Ethernet ( thinwire MAU ) is the culprit. A PCI device works, while ping on the internal NI has >80% error rate. It is a technical University and so we have lots of environmental factors to check, but it looks like the BNC connector has its outer connection ( ground or shield ) connected to the chassis ground !!! Is this correct ? I will be able to verify this as soon as I get a MAU. Can a proud owner of such a fast machine tell me that it's not true ? /Azfar Khan

39.2 | Possible MAU installation error ? ("What's this plastic for?") | BBPBV1::WALLACE | john wallace @ bbp. +44 860 675093 | Wed Feb 05 1997 04:52 | 10 |
If it's the same MAU as on the 255, it should have a nylon bush between the coax socket and the chassis. If the MAU has been field installed by someone who didn't understand, they may have discarded the nylon bush (apparently it needs to be fitted from the *outside* of the box whereas the socket is fitted from the inside). does this help ? regards john |
