Note
The NI 9155 requires a host system with a PCI Express clock that complies with the PCI Express Specification. The NI 9155 may not be compatible with systems using noncompliant clocks, particularly clocks with peak frequencies higher than 100 MHz. For more information about PCI Express clock compatibility with the NI 9155, go to ni.com/info and enter the Info Code 915xclock.

Installing C Series Modules

The following figure shows the mechanical dimensions of C Series I/O modules.
Figure 1. C Series I/O Module, Front and Side View with Dimensions

Complete the following steps to install a C Series I/O module in the chassis.

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.
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.

Insertion Groove
Latch
Squeeze the latches and insert the I/O module into the module slot.
Press firmly on the connector side of the I/O module until the latches lock the I/O module into place.
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.

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.
Squeeze the latches on both sides of the module and pull the module out of the chassis.

Connecting the NI 9155 to the Ground

You must connect the NI 9155 grounding terminal to the grounding electrode system of the facility.

What to Use

Ring lug
Wire, 2.05 mm2 (12 AWG) or larger
Screwdriver, Phillips #2

What to Do
Complete the following steps to ground the NI 9155.

Attach the ring lug to the wire.
Remove the grounding screw from the grounding terminal on the NI 9155.
Attach the ring lug to the grounding terminal.
Tighten the grounding screw to 0.5 N · m (4.4 lb · in.) of torque.
Attach the other end of the wire to the grounding electrode system of your facility using a method that is appropriate for your application.

Caution If you use shielded cabling to connect to a C Series module with a plastic connector, you must attach the cable shield to the chassis grounding terminal using 1.3 mm diameter (16 AWG) or larger wire. Attach a ring lug to the wire and attach the wire to the chassis grounding terminal. Solder the other end of the wire to the cable shield. Use shorter wire for better EMC performance. For more information about ground connections, visit ni.com/info and enter the Info Code campground.

Connecting One or More NI 9155 Chassis to the MXI-Express Host System or a Target

Complete the following steps to connect one or more NI 9155 chassis to an MXI- Express host system or a target.

Make sure the MXI-Express host system is set up and configured as described in the MXI-Express (x1) Series User Manual.
If the MXI-Express host system is powered up, power it down.
If the NI 9155 is powered up, power it down.
Use an MXI-Express (x1) cable to connect the MXI-Express host system to the Upstream port of the first NI 9155 in the chain.
Use an MXI-Express (x1) cable to connect the Downstream port of the first NI 9155 to the
Upstream port of the next NI 9155 in the chain.
Note The maximum number of NI 9155 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.
Power up all of the connected NI 9155 chassis.
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 9155 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.

Wiring Power to the Chassis

The NI 9155 requires an external power supply that meets the specifications. The NI 9155 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 9155 has one layer of reverse voltage protection. Complete the following steps to connect a power supply to the chassis.

Connect the positive lead of the power supply to the V1 or V2 terminal of the COMBICON connector shipped with the NI 9155.
Connect the negative lead of the power supply to one of the C terminals of the COMBICON connector.
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.
Install the COMBICON connector on the front panel of the NI 9155.

Caution To ensure the specified EMC performance, do not connect the power input to a DC mains supply or to any supply requiring a connecting cable longer than 3 m (10 ft). A DC mains supply is a local DC electricity supply network in the infrastructure of a certain site or building.
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.

Chassis Powerup Options

The following table lists the reset options available for the NI 9155. 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.

Table 1. Chassis Powerup Options

Powerup Option	Behavior
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.

If you want the NI 9155 to autoload and run a VI at powerup, you must also configure the VI to autoload before you compile it. For more information about autoloading VIs, refer to 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 9155 indicate the following:

Table 2. NI 9155 MXI-Express LINK LED Indications

LINK LED Appearance	Meaning
Off	The chassis power is off.
Solid yellow	The link is not established.
Solid green	The link is established.
Blinking yellow	PCI Express clock is incompatible with NI 9155

Note For information about PCI Express clock compatibility with the NI 9155, 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 9155 chassis. When the host system is powered down, the order in which the NI 9155 chassis are powered down is not important.
