Set Up Your MXI -Express x4
System
This document explains what you will need to set up various
MXI-Express x4 hardware configurations.
The products covered by this guide are the NI PCIe-8371/8372 and
NI PXIe-8370/8374. For the remainder of this manual the term
MXI-Express x4 product refers to any of these products.
Additional compatible products are included in subsequent tables, but are
not covered in this manual.
Terminology
The following terms may be used throughout this document:
•Host PC—A host computer with at least one PCI Express x4 or wider
slot available.
Note Using a PCI Express slot wider than x4 may result in negotiation down to x1 width,
and therefore limiting bandwidth. This is uncommon in newer PCs.
•Expansion Chassis—An expansion chassis of any of the following
types:
– CompactPCI Express chassis
– PXI Express chassis
– NI HDD RAID
•MXI-Express x4 copper cable—Standard PCI Express specification
compliant cable with x4 PCIe connectors.
Note Refer to the Cabling section for details. Most MXI-Express kits include the cable,
but not all.
•Host Board—The MXI-Express x4 board of a cabled pair of boards
that is closer to the CPU.

that is farther from the CPU.
•Cabled Pair—Two MXI-Express x4 boards that are connected with a
single cable.

Installation and Configuration
This section explains how to unpack, install, and configure the
MXI-Express x4 hardware and software.
Unpacking
Your MXI-Express x4 cards are shipped in antistatic packages to prevent
electrostatic damage (ESD) to the devices. ESD can damage several
components on the device.
Caution Never touch the exposed pins of connectors. Doing so may damage the device.
To avoid such damage in handling the device, take the following
precautions:
• Ground yourself using a grounding strap or by holding a grounded
object.
• Touch the antistatic package to a metal part of the computer chassis
before removing the device from the package.
Remove the device from the package and inspect the device for loose
components or any sign of damage. Notify NI if the device appears
damaged in any way. Do not install a damaged device into the computer or
into a PXI Express or CompactPCI Express chassis.
Store the device in the antistatic envelope when not in use.

Hardware Installation
The following are general instructions for installing the MXI-Express x4
cards. Consult your computer user manual or technical reference manual
for specific instructions and warnings.
Installing an NI PCIe-8371/8372
Complete the following steps to install the NI PCIe-8371/8372 in your
computer.
1. Power off your computer.
Caution To protect both yourself and the computer from electrical hazards, your computer
should remain off until you finish installing all hardware as instructed.
2. Remove the top cover or access port to the PCI Express expansion
slots.
3. Touch the metal part of the power supply case inside the computer to
discharge any static electricity that might be on your clothes or body.
4. Unplug the computer and wait 30 seconds to allow the energy stored
in the computer’s power supply to fully dissipate.
5. Select any available PCI Express expansion slot (x4 or wider).
Note Using a PCI Express slot wider than x4 may result in negotiation down to x1 width,
which will reduce throughput performance. This is rare in modern systems.
Note The BIOS or motherboard may not support the NI PCIe-8371/8372 in a slot intended
for a graphics card.
Note Not all PCI Express expansion slots that have x4 or wider physical connectors are
electrically capable of x4 PCI Express operation. Check with the motherboard
manufacturer to verify that the slot is capable of x4 PCI Express operation.
6. Locate the metal bracket that covers the cut-out in the back panel of the
computer for the slot you have selected. Remove and save the
bracket-retaining screw and the bracket cover.
7. Line up the NI PCIe-8371/8372 with the slot on the back panel. Slowly
lower the NI PCIe-8371/8372 until its card-edge connector is resting
on the expansion slot receptacle. Using slow, evenly distributed
pressure, press the NI PCIe-8371/8372 straight down until it seats in
the expansion slot, as shown in Figure 1.
8. Secure the NI PCIe-8371/8372 to the back panel rail using a bracket
retaining screw.

9. Replace the computer cover.
10. Plug the computer back in.
Figure 1. Installing the NI PCIe-8371/8372
Installing the Low-Profile Bracket on the NI PCIe-8371 (Optional)
To install the NI PCIe-8371 in a host computer that requires a low-profile
height card, the front bracket must be replaced with the low-profile bracket
included with your kit. Complete the following steps to replace the bracket.
1. Remove the standard height front bracket already installed on your
NI PCIe-8371 card by removing the two 4-40 × 1/4 inch Phillips head
screws that attach the bracket to the card. Note that the two mounting
tabs for the standard height bracket rest against the front side of the
card, which is the side upon which the cable receptacle connector
housing rests. Set the two screws aside to re-use when installing the
low-profile bracket.

Caution When removing the bracket, be careful not to remove or lose the EMI gasket on
the cable receptacle connector housing.
2. Fit the low-profile bracket onto the NI PCIe-8371. Note that the
two mounting tabs that the screws thread into rest against the back side
of the card for the low-profile bracket. Ensure that the front bracket
LED bulb is situated in the display hole correctly.
3. Align the mounting holes on the card with the threaded holes on the
mounting tabs of the bracket, and insert the screws from the front side.
4. Tighten each screw to a maximum torque of 3.6 lb · in. (0.407 N · m).

Installing an NI PXIe-8370 or NI PXIe-8374
Table 3 provides information on which PXI Express MXI-Express x4
boards are compatible with which chassis slot types.
Note For this section, all of the above products will be referred to as an “NI PXI Express
board”.
Complete the following steps to install the NI PXI Express board in your
PXI Express or CompactPCI Express chassis.
1. Power off your PXI Express or CompactPCI Express chassis, but leave
it plugged in while installing the NI PXI Express board. The power
cord grounds the chassis and protects it from electrical damage while
you install the module.
Caution To protect both yourself and the chassis from electrical hazards, leave the chassis
off until you finish installing the NI PXI Express board.
2. Remove or open any doors or covers blocking access to the slot in
which you intend to install the NI PXI Express board.
3. Touch a metal part of the chassis to discharge any static electricity that
might be on your clothes or body.
4. Make sure the injector/ejector handle is in its downward position.
Be sure to remove all connector packaging and protective caps from
retaining screws on the module. Align the NI PXI Express board with
the card guides on the top and bottom of the system controller slot.
Caution Do not raise the injector/ejector handle as you insert the NI PXI Express board.
It will not insert properly unless the handle is in its downward position so that it does not
interfere with the injector/ejector rail on the chassis, as shown in Figure 3.
5. Hold the handle as you slowly slide the module into the chassis until
the handle catches on the injector/ejector rail.

6. Raise the injector/ejector handle until the module firmly seats into the
backplane receptacle connectors. The front panel of the NI PXI
Express board should be even with the front panel of the chassis.
Note LEDs on the back side of the NI PXIe-8370 will light, indicating the presence of 5 V
auxiliary power. Refer to the LED Indicators section for details.
7. Tighten the bracket-retaining screws on the top and bottom of the front
panel to secure the NI PXI Express board to the chassis.
8. Replace or close any doors or covers to the chassis.
