我们现在又有了新的现象,可能与上面的问题有关:
在测试的过程中,当自检电源时报错:
R350 The power supplies are in over-voltage protection.The over-voltage levels have been programmed to the maximum allowable level for each supply.Check to see that this voltage has not been exeeded on the board.The over-voltage protection circuitvy may also be tripped if small negative voltages (even tenths of volts) are present on the board, or if there is a problem with the power supply sense connections to the board.One supply with an over-voltage condition may cause the other supplied to pull over-voltage,,so be sure to check all supplies at line 2284.
这个和什么可能有关系?? |
