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.
