  • Page 9: Wiring Power To The Chassis

    Wiring Power to the Chassis The NI 9148 requires an external power supply that meets the specifications in the Power Requirements section. The NI 9148 filters and regulates the supplied power and provides power for all of the I/O modules.
  • Page 10 The C terminals are internally connected to each other. Powering On the NI 9148 When you apply power to the NI 9148, the chassis runs a power-on self test (POST). During the POST, the Power and Status LEDs turn on. The Status LED turns off, indicating that the POST is complete.

  • Page 11: Configuring Ip Settings

    Configuring IP Settings When you power on the NI 9148 for the first time, it boots into safe mode because there is no software installed on it. This section describes how to configure the IP settings and install software on the chassis.

  • Page 12: Configuring Dip Switches

    Safe mode is for troubleshooting, updating configuration, and installing software. Keep the SAFE MODE switch in the OFF position during normal operation. If the switch is in the ON position at startup, the NI 9148 launches only the essential services required for updating configuration and installing software.
