    Power disconnect

    The DC power cable provides main power disconnect. Do not position the equipment so that it is difficult to disconnect the power cord. The front panel power switch causes the internal chassis power supply to provide DC power to the CompactPCI/PXI Express backplane. You also can use the rear-panel D-SUB 9-pin connector and power mode switch to control the internal chassis power supply.


    Use the DC power cable provided with DC power supplies for VDC input.


    Using the PXIe-1082DC in a manner not described in this document may impair the protection the PXIe-1082DC provides.
