Connecting the sbRIO-9637 to Power
The NI sbRIO device requires a 9 VDC to 30 VDC external power supply. The NI sbRIO
device filters and regulates the supplied power and provides power for RMCs.
Note Refer to the Power Requirements section of the NI sbRIO-9637
Specifications for the complete power requirement specifications.
Note Refer to the Power Requirements section of the NI sbRIO-9637 User Manual
for formulas and examples for calculating power requirements for different
configurations and application types.
Note Refer to the Power Requirements section of the NI sbRIO-9637 User Manual
for proper wiring of the power cable assembly.
Complete the following steps to connect a power supply to the device.
Caution Do not mate or unmate the power supply connectors while power is
applied.
1. Ensure that your power supply is powered off.
2. Insert the power connector plug into the power connector receptacle of the NI sbRIO
device until the connector latches into place.

Powering On the NI sbRIO Device
The NI sbRIO device runs a power-on self test (POST) when you apply power to the device.
During the POST, the Power and Status LEDs turn on. When the Status LED turns off, the
POST is complete. If the LEDs do not behave in this way when the system powers on, refer to
the STATUS LED Indicators section.
Connecting the sbRIO-9637 to the Host Computer
Complete the following steps to connect the sbRIO-9637 to the host computer using the RJ-45
Ethernet port.
1. Power on the host computer.
2. Connect the sbRIO-9637 to the host computer using a standard Category 5 (CAT-5) or
better shielded, twisted-pair Ethernet cable.
Caution To prevent data loss and to maintain the integrity of your Ethernet
installation, do not use a cable longer than 100 m.
The first time you power up the device, it attempts to initiate a DHCP network
connection. If the device is unable to initiate a DHCP connection, it connects to the
network with a link-local IP address with the form 169.254.x.x. After the device has
