The following sections give instructions for the mounting methods. Before using any of these
mounting methods, record the serial number from the back of the chassis. You will be unable
to read the serial number after you have mounted the chassis.
Caution Make sure that no I/O modules are in the chassis before mounting it.
Mounting the Chassis on a Panel
You can use the NI 9905 panel mount kit to mount the NI 9148 on a flat surface. Complete the
following steps to mount the NI 9148 on a panel.
1. Fasten the chassis to the panel mount kit using a number 2 Phillips screwdriver and two
M4 × 25 screws. National Instruments provides these screws with the panel mount kit.
NI 9148 User Manual | © National Instruments | 5

You must use these screws because they are the correct depth and thread for the panel.
Tighten the screws to a maximum torque of 1.3 N · m (11.5 lb · in.).

Caution Make sure that no I/O modules are in the chassis before removing it
from the panel.
Mounting the Chassis on a DIN Rail
You can order the NI 9915 DIN rail mount kit to mount the NI 9148 on a DIN rail. You need
one clip for mounting the chassis on a standard 35 mm DIN rail. Complete the following steps
to mount the chassis on a DIN rail.

Removing I/O Modules from the Chassis
Complete the following steps to remove a C Series I/O module from the chassis.
1. Make sure that no I/O-side power is connected to the I/O module.
2. Squeeze the latches on both sides of the module and pull the module out of the chassis.
Connecting the Chassis to a Network
Connect the chassis to an Ethernet network using Ethernet port 1 on the front panel. Use a
standard Category 5 (CAT-5) or better shielded, twisted-pair Ethernet cable to connect the
chassis to an Ethernet hub or a computer.
NI 9148 User Manual | © National Instruments | 9

Caution To prevent data loss and to maintain the integrity of your Ethernet
installation, do not use a cable longer than 100 m.
If you need to build your own cable, refer to the Cabling section for more information about
Ethernet cable wiring connections.
Note You will configure the IP settings as described in the Configuring IP Settings
section, after connecting power and powering the chassis on.
The host computer communicates with the chassis over a standard Ethernet connection. If the
host computer is on a network, you must configure the chassis on the same subnet as the host
computer. If neither the host computer nor the chassis is connected to a network, you can
connect the two directly using a crossover cable.
If you want to use the chassis on a subnet other than the one the host computer is on, first
connect the chassis on the same subnet as the host computer. Use DHCP to assign an IP
address or reassign a static IP address for the subnet where you want it to be and physically
move it to the other subnet.
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. The NI 9148 has one layer of reverse-voltage protection. Complete the following
steps to connect a power supply to the chassis.
1. Ensure that the power supply is turned off.
2. Connect the positive lead of the power supply to the V terminal of the COMBICON
power connector shipped with the NI 9148, and tighten the terminal screw. The following
figure shows the terminal screws, which secure the wires in the screw terminals, and the
connector screws, which secure the power connector on the controller.

4. Install the power connector on the front panel of the NI 9148 and tighten the connector
screws.
5. Turn on the power supply.
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. If the LEDs do not behave in this way when the system powers on, refer to
the Understanding LED Indications section.
Chassis Startup Options
The following table lists the startup options available for the NI 9148. These options determine
how the chassis behaves when it starts up in various conditions. Use the RIO Device Setup
utility to select startup options. Access the RIO Device Setup utility by selecting Start»All
Programs»National Instruments»NI-RIO»RIO Device Setup.

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.
1. Launch MAX on the host computer and expand Remote Systems in the MAX
configuration tree. MAX lists the NI 9148 as the model name of the chassis followed by
the serial number, for example, NI9148-XXXXXXXX.
The chassis automatically attempts to connect to the network using DHCP. If DHCP is
not available, the chassis connects to the network with a link-local IP address with the
form 169.254.x.x. You must connect the chassis directly to the host computer to
configure it in this state.
2. Select the chassis under Remote Systems to see the Network Settings tab in the middle
pane of MAX.
3. Enter a name for the chassis in the Name field.
NI 9148 User Manual | © National Instruments | 11

4. Select settings for the chassis in the IP Settings section, then click Apply.
Note For information about configuring network settings, refer to the
Configuring Network Settings book of the MAX Remote Systems Help. In
MAX, click Help»Help Topics»Remote Systems. On the Contents tab,
browse to LabVIEW Real-Time Target Configuration»Configuring
Network Settings.
5. When you click Apply, you are prompted to reboot the chassis for the changes to take
effect. Click Yes. You can also reboot the chassis by right-clicking the name under
Remote Systems and selecting Reboot.
6. After rebooting, the chassis appears under Remote Systems with the assigned name.
Expand the chassis and select Software.
7. Click Add/Remove Software in the toolbar to launch the LabVIEW Real-Time Software
Wizard.
8. Install the Recommended Software Set that appears in the LabVIEW Real-Time Software
Wizard.
For more information about configuring the chassis in MAX, refer to the MAX Help. For
information about installing and using LabVIEW FPGA, refer to the LabVIEW FPGA Module
Release and Upgrade Notes.
Configuring DIP Switches

SAFE MODE Switch
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.
Push the SAFE MODE switch to the ON position if the software on the chassis is corrupted.
Even if the switch is not in the ON position, if there is no software installed on the chassis, the
chassis automatically boots into safe mode. The SAFE MODE switch must be in the ON
position to reformat the drive on the chassis. Refer to the Measurement & Automation
Explorer Help for more about installing software and reformatting the drive.
IP RESET Switch
Push the IP RESET switch to the ON position and reboot the chassis to reset the IP address
and other TCP/IP settings of the chassis to the factory defaults. Refer to the Troubleshooting

Troubleshooting Network Communication
If the NI 9148 cannot communicate with the network, you can perform the following
troubleshooting steps.
1. Move the IP RESET switch to the ON position.
2. Disconnect and reconnect chassis power.
3. Move the IP RESET switch to the OFF position.
4. Configure the IP and other network settings in MAX.
Restoring the BIOS Network Settings
If you are unable to fix network communication with the network settings restored, you can
restore the BIOS network settings of the chassis. Refer to the Configuring IP Settings section
for information about the BIOS network settings for different chassis revisions. Complete the
following steps to restore the BIOS network settings of the chassis.
1. Move the IP RESET and SAFE MODE switches to the ON position.
2. Disconnect and reconnect chassis power.
