Replaced the UPS logic board and it seems like the communications problem is still there. GONG guys will check it better tomorrow. I put the old logic board in the box with several other UPS boards that is kept in the shed. Also tried several other things including swapping the Data CPU board, that didn't help so I swapped it back. Didn't swap back the UPS logic board because of how long it takes and the danger of working near those huge capacitors in the UPS. Put everything else back how it was. ___end___ WEATHER COMMENT: Wed Dec 19 01:45:31 GMT 2007 Cloudy all day. ___end___ **PICS PROBLEM**: Wed Dec 19 01:45:48 GMT 2007 Bunny fixed the error message problem, it was a bad memory block. ___end___ Wed Dec 19 01:48:15 GMT 2007 MkIV
