Mounting the NI 9157/9159

You can mount the chassis horizontally on a 35 mm DIN rail or on a flat, vertical, metallic
surface such as a panel or wall. The maximum allowable ambient temperature for operation is
55 °C. Mounting the chassis in a different orientation or on a nonmetallic surface can reduce
the maximum allowable ambient temperature and can affect the typical accuracy of modules in
the chassis. The following figure shows the chassis mounted horizontally.

Figure 2. NI 9157/9159 Mounted Horizontally

Measure the ambient temperature at each side of the chassis, 63.5 mm (2.5 in.) from the side
and 50.8 mm (2 in.) forward from the rear of the chassis.

Note For more information about typical accuracy specification for modules, go to

ni.com/info and enter the Info Code criotypical.

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 DIN Rail

Use the DIN rail mounting method if you already have a DIN rail configuration or if you need
to be able to remove the chassis quickly. You can order the NI 9916 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 three
M4 x 50 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.).

Panel or wall mounting is the best method for applications that are subject to high shock and
vibration. You can use the NI 9907 panel mount kit to mount the NI 9157/9159 on a flat
surface. Complete the following steps.

1. Fasten the chassis to the panel mount kit using a number 2 Phillips screwdriver and six
M4 x 50 screws. NI provides these screws with the panel mount kit. Tighten the screws to
a maximum torque of 1.3 N · m (11.5 lb · in.).

the panel.

Mounting the Chassis Directly on a Flat Surface Using
the Mounting Holes

Panel or wall mounting is the best method for high shock and vibration applications. If you do
not have the NI 9907 panel mount kit and do not require the portability that the NI 9907
affords, you can mount the NI 9157/9159 directly on a flat surface using the three mounting
holes. Complete the following steps.

1. Align the chassis on the surface.

2. Fasten the chassis to the surface using three M4 or number 8 screws. NI does not provide
these screws with the chassis.

5. Repeat these steps to install additional I/O modules.

Removing C Series Modules

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.

Wiring Power to the Chassis

The NI 9157/9159 requires an external power supply that meets the specifications. The
NI 9157/9159 filters and regulates the supplied power and provides power for all of the I/O
modules. You must connect a power supply to at least one pair of V and C terminals.
Optionally, you can connect a second power supply to the other pair of V and C terminals. The
chassis draws power from the power supply with the higher voltage. The NI 9157/9159 has
one layer of reverse-voltage protection. Complete the following steps to connect a power
supply to the chassis.

1. Connect the positive lead of the power supply to the V1 or V2 terminal of the
COMBICON connector shipped with the NI 9157/9159.

2. Connect the negative lead of the power supply to one of the C terminals of the
COMBICON connector.

3. Optionally you can connect the positive lead of another power supply to the other V
terminal and the negative lead to one of the C terminals.

4. Install the COMBICON connector on the front panel of the NI 9157/9159.

Note The chassis draws power from either V1 or V2 depending on which

terminal has a higher voltage. It does not draw power from both terminals. The
chassis switches between V1 and V2 without affecting operation.

Note If you prefer for the chassis to draw power from one power supply, you

must ensure that the voltage of that power supply, measured at the chassis
power connector, is at least 500 mV higher than the voltage of the other power
supply.

Caution The C terminals are internally connected to each other. If you use

two power supplies, make sure that they share a common ground.

Caution The C terminals are internally connected to the body of the chassis to

prevent a faulty ground connection from causing the chassis ground to float. If
you reverse the input voltage, the positive input voltage is connected directly to
the chassis. The chassis has built-in reversed-voltage protection, but reversed
voltage can damage connected peripherals if the chassis ground is not reliably
connected to earth ground.

Caution Do not tighten or loosen the terminal screws on the power connector

while the power connector is plugged into the chassis or while the power
supply is on.

Connecting One or More NI 9157/9159 Chassis
to the MXI-Express Host System or a Target

Complete the following steps to connect one or more NI 9157/9159 chassis to a MXI-Express
host system or a target.

NI 9157/9159 User Manual and Specifications | © National Instruments | 11

1. Make sure the MXI-Express host system is set up and configured as described in the
MXI-Express (x1) Series User Manual.

2. If the MXI-Express host system is powered up, power it down.

3. If the NI 9157/9159 is powered up, power it down.

4. Use a MXI-Express (x1) cable to connect the MXI-Express host system to the Upstream
port of the first NI 9157/9159 in the chain.

5. Use a MXI-Express (x1) cable to connect the Downstream port of the first NI 9157/9159
to the Upstream port of the next NI 9157/9159 in the chain.

Note The maximum number of NI 9157/9159 chassis in a chain depends on

the system configuration. For example, a PXI system with an NI PXI-8196
controller can support four chassis per chain. Different types of systems may
support more or fewer chassis per chain. For more information about how
different system configurations can affect the maximum number of chassis in a
chain, go to ni.com/info and enter the Info Code 915xchain.

6. Power up all of the connected NI 9157/9159 chassis.

7. Power up the MXI-Express host system.

Note Refer to the MXI-Express (x1) Series User Manual for connectivity

options and supported host devices.

Caution All connected NI 9157/9159 chassis must have power connected

before the host system is powered up. The BIOS and OS of the host system
must detect all bus segments on the chassis side in order to configure the PCI
hierarchy. Powering connected chassis up or down while the host system is
running can cause system hangs and data corruption.

Caution Do not remove MXI-Express (x1) cables while power is connected.

Doing so can cause hangs or application errors. If a cable becomes unplugged,
plug it back in and reboot.

Chassis Powerup Options

The following table lists the reset options available for the NI 9157/9159. These options
determine how the chassis behaves when it is powered on in various conditions. Use the RIO
Device Setup utility to select reset options. Access the RIO Device Setup utility by selecting
Start»All Programs»National Instruments»NI-RIO»RIO Device Setup.

the LabVIEW FPGA Module Help.

Checking MXI-Express LINK LEDs for Status

After powering on the chassis and host system, check the MXI-Express LINK LEDs to ensure
that all connected systems are linked and communicating properly. The MXI-Express LINK
LEDs of the NI 9157/9159 indicate the following:

Table 2. NI 9157/9159 MXI-Express LINK LED Indications

LINK LED Appearance Meaning

Note For information about PCI Express clock compatibility with the

NI 9157/9159, go to ni.com/info and enter the Info Code 915xclock.

Powering Down the MXI-Express System

Always power down the host system before powering down any connected NI 9157/9159
chassis. When the host system is powered down, the order in which the NI 9157/9159 chassis
are powered down is not important.
