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.

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.

Cable Length

(Meters)

3 m MXI-Express x4 copper cable 779725-03

7 m MXI-Express x4 copper cable 779725-07

Connect the MXI-Express x4 cable to both MXI-Express x4 cards. The cables have no polarity, so either end may be connected to either card.

Caution Do not remove the cable after the system is powered on. Doing so can hang

or cause errors in applications communicating with devices behind MXI-Express x4. If a cable becomes unplugged, plug it back into the system. (You may need to restart your computer.)

Powering On the MXI-Express x4 System

1. Power-on all of the expansion chassis in any order you choose.

2. Power-on the host.

available from National

Description Part Number

Note There are no requirements on how MXI-Express x4 expansion chassis are powered

up relative to each other, as long as they are all on before the computer is powered on.

3. Observe the LED status on the NI PCIe-8371, NI PCIe-8372, NI PXIe-8370 and NI PXIe-8374 where applicable. A properly connected and powered up system should report a valid link and power status on all of these boards once the host PC is powered on. Refer to the LED Indicators section for more information.

Typical PCI-PCI bridges and switches are used to add PCI devices to a PCI hierarchy in which all the bridges and devices are contained within a single chassis. Because of this, BIOSes and operating systems make the assumption that all PCI devices in the entire hierarchy will be available as soon as code execution begins at power-up time. This assumption means that all of the expansion chassis must be turned on before the host PC for the BIOS and OS to correctly configure a MXI-Express x4 system.

For more information, refer to the Terminology section.

Powering Off the MXI-Express x4 System

Because operating systems and drivers commonly make the assumption that PCI devices will be present in the system from power-up to power-down, it is important to not power off the expansion chassis until after the host PC is powered off. Powering off the expansion chassis while the host is still on can cause crashes or hangs. However, once the host pc is powered off, the order that the expansion chassis are powered off is not important.

Note To power down the chassis while the host computer or host chassis is on, you may

need to hold the power button for at least four seconds. However, this behavior cannot be guaranteed.

LED Indicators

The LEDs on MXI-Express x4 cards give status information about power supplies and link state. The NI PCIe-8371 and NI PXIe-8374 have one tri-color LED on the panel, indicating power and link status. The NI PCIe-8372 has two tri-color LEDs on the panel, indicating power and link status for each port. The NI PXIe-8370 has two LEDs, one for power supply status and one for link state.

The NI PXIe-8370 also has a vertical column of 16 LEDs on the back panel

of the card near the front connector, as shown in Figure 5. These LEDs provide additional information about the link status of the PCI Express lanes on the module to the backplane. Each group of four LEDs corresponds to one of the four PCI Express links to the backplane.

Notes

If you are using a chassis (such as the NI PXIe-1062) that directly links the PXI Express board, the LEDs to that slot will not illuminate until you have a PXI Express board installed and linked.

If you are using the NI PXIe-1062 chassis, you will notice that the last group of LEDs has an LED (PORT 3) illuminated even if no boards are populated in the slots. Since the NI PXIe-1062 uses the last link for a PCI Express to PCI bridge for PXI communication, this link should always be active. Different chassis topologies will give different default behaviors. Contact your chassis’ manufacturer for more information on your chassis’ topology.
