Page 25: Maintenance Philosophy
GENERAL the REPT:PA printout which would identify the frame with power fault. The precise structure of the message is given The maintenance philosophy contained in this volume is in the input/output (I/O) message manuals. The symptoms based upon the design of equipment (hardware), diagnostic described in the IXL reflect the assumptions above, and software and test equipment employed.
Page 26 on three levels. Level one [TAP-101] addresses what to do access TOP documents at a point in trouble-clearing where with a software-generated TLP SUSPECTED FAULTY EQUIPMENT analyzation is completed (faulty component determined) and only repair or replacement required. In many instances, list and provides a step-by-step procedure for replacing circuit packs one at a time, and analyzing the results.
