Disk Drive Power Connector Installation
Before installing the disk drive power connector, you must install and set
up the R Series PCI Express device as described in the Getting Started with
R Series Multifunction RIO document. Complete the following steps to
install the disk drive power connector.
1. Power off and unplug the computer.
2. Remove the computer cover.
3. Attach the PC disk drive power connector to the disk drive power
connector on the device, as shown in Figure 2-19.
Note The power available on the disk drive power connectors in a computer can vary. For
example, consider using a disk drive power connector that is not in the same power chain
as the hard drive.

5. Use the NI 78xxR Calibration Utility to run a self-calibration on the
NI PCIe-784xR/785xR device. Refer to the Self-Calibration section of
Chapter 3, Calibration (NI 783xR/784xR/785xR Only), for more
information.
Note Connecting or disconnecting the disk drive power connector can affect the analog
performance of your device. To compensate for this, NI recommends that you
self-calibrate after connecting or disconnecting the disk drive power connector.
