Installing the Auxiliary 48 V Power Source on the PXIe-4151

Complete the following steps to install the auxiliary 48 V power source on the PXIe-4151 and prepare it for use.
  1. Connect the power source to the auxiliary power input connector on the PXIe-4151 front panel using a 6-pos to 4-pos cable rated for ≥60 V/≥15 A. Refer to the AUX I/O Connector pinout in the PXIe-4151 Pinouts topic for more information.
  2. Tighten the screws to hold the auxiliary 48 V power source in place.
    Note An auxiliary 48 V power source is required to operate the PXIe-4151. NI recommends using a power source that is greater than 9 A. The auxiliary power source provided by NI uses sufficient wire gauge to maintain voltage requirements for the device. If you use a third-party auxiliary power source, you must use the appropriate wire gauge to ensure that it can provide the required device current without dropping below the minimum voltage at the auxiliary power input connector
