These appear to be designed to monitor voltages from 0-18V. http://pdf1.alldatasheet.com/datasheet-pdf/view/177129/TI/TL7705BC.html http://pdf1.alldatasheet.com/datasheet-pdf/view/177128/TI/TL7702BC.html They are labeled as U33 and I believe U32 on this card. (The U32 is not clearly readable on the pcb). These are located above the SIMM slot on the IO card. http://www.bsd.am/IMG_4312.JPG (warning, hi-res) HTH, B _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
