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

.

Do Not Autoload VI

Does not load the FPGA bit stream from flash memory.

Autoload VI on device powerup Loads the FPGA bit stream from flash memory to the

FPGA when the chassis powers on.
