Set Up Your MXI-Express x4 System
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.
