Main rack contained power supply 140cps52400 and 140cpu43412A and RIO HEAD 140CRP93100 in addition to another I/o cards . Another remote rack containe power supply 140 cps51100 and RIO DROP(140CRA93100) in addition to another i/o cards digital and analog.
As we know RIO HEAD and RIO DROP connected to each other using coaxial table.
The problem occurs suddenly no power on the i/o cards of remote rack and error ERROR A appeared on the RIO HEAD OF THE MAIN RACK.
For the first time i think the power supply in remote rack damage and shut off all related cards in that rack but the power supply tell me pwr ok as on it's display. Then i tightin the coaxial cable on the RIO DROP and the power back to the i/o cards, i can't understand why when tighten the coaxial cabe the power pack to i/o cards.
