Note The cRIO-9072/9073/9074 may be shipped with a clear protective film cover
on the front panel. You can remove the film cover before installing the
cRIO-9072/9073/9074.
Mounting the CompactRIO Reconfigurable
Embedded Chassis
You can mount the chassis in any orientation on a 35 mm DIN rail or on a panel. Use the DIN
rail mounting method if you already have a DIN rail configuration or if you need to be able to
quickly remove the CompactRIO chassis. Use the panel mount method for high shock and
vibration applications.
Caution Your installation must meet the following requirements for space and
cabling clearance:
• Allow 25.4 mm (1 in.) on the top and the bottom of the chassis for air
circulation.
• Allow 50.8 mm (2 in.) in front of modules for cabling clearance for common
connectors, such as the 10-terminal, detachable screw terminal connector.

The following sections contain 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
Panel or wall mounting is the best method for applications that are subject to high shock and
vibration. You can use the NI 9905 panel mount kit to mount the cRIO-9072/9073/9074 on a
flat surface. Complete the following steps.
1. Fasten the chassis to the panel mount kit using a number 2 Phillips screwdriver and two
M4 × 16 screws. NI provides these screws with the panel mount kit. 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 if you want to mount the chassis 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.
1. Fasten the DIN rail clip to the chassis using a number 2 Phillips screwdriver and two
M4 × 16 screws. NI provides these screws with the DIN rail mount kit. Tighten the
screws to a maximum torque of 1.3 N · m (11.5 lb · in.).

Complete the following steps to install a C Series I/O module in the chassis.
1. Make sure that no I/O-side power is connected to the I/O module. If the system is in a
nonhazardous location, the chassis power can be on when you install I/O modules.
2. Align the I/O module with an I/O module slot in the chassis. The module slots are labeled
1 to 8, left to right.

4. Press firmly on the connector side of the I/O module until the latches lock the I/O module
into place.
5. Repeat these steps to install additional I/O modules.
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. If the system is in a
nonhazardous location, the chassis power can be on when you remove I/O modules.
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 the RJ-45 Ethernet port on the controller
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 use an Ethernet crossover cable to connect the
chassis directly to a computer.
NI cRIO-9072/9073/9074 User Manual and Specifications | © 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.
The first time you power up the chassis, the BIOS network settings determine the initial IP
settings and other network behavior. After powerup, you must install software on the chassis
and configure the network settings in NI Measurement & Automation Explorer (MAX).
Note Installing software may change the network behavior of the chassis. For
information about network behavior by installed software version, go to ni.com/info
and enter the Info Code ipconfigcrio.
The BIOS network settings of the cRIO-9072/9073/9074 depend on the part number of the
chassis. The part number is located on the bottom of the chassis.
BIOS Network Settings of cRIO-9072/9073/9074 with
Part Number Beginning 192172
If the part number of the cRIO-9072/9073/9074 begins with 192172, the IP address, subnet
mask, DNS address, gateway, and Time Server IP are all set to 0.0.0.0 at powerup.
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.
BIOS Network Settings of cRIO-9072/9073/9074 with
Part Number Beginning 198944
If the part number of the cRIO-9072/9073/9074 begins with 198944, the chassis attempts to
initiate a DHCP network connection at powerup. If the chassis 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.
The host computer communicates with the chassis over a standard Ethernet connection. If
neither the host computer nor the chassis is connected to a network, you can connect the two
directly using a crossover cable.
Connecting the Chassis to Earth Ground
You must connect the chassis grounding screw to earth ground. Complete the following steps
to connect to earth ground.
1. Attach a ring lug to a 1.6 mm2 (14 AWG) or larger wire.
