Machine is down for maintenance. All ribbon cables, arcnet, denet, ionet cables checked and are fine and firmly inserted to sockets. SDCC and SLCC cards, swapped from t core to s core,TCDA swapped from S to T but no difference in prevote data,core T reads mismatch for above mentioned logic points. TCEA and TCQC cables checked all in good condition.
Powersupply voltage from T core on Diagc shows P15 = 17 Vdc, N15 = -17 Vdc,P24 =29 Vdc, N24 = -30 Vdc. P5 = 5.02 Vdc
Where can be the fault. kindly advice
Thanks
