Hardware Installation
Powering Up the MXI-Express System
1. Power-on all of the expansion chassis in any order you choose.
2. Power-on the host.
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. 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 system.
Note There are no requirements on how MXI-Express expansion chassis are powered up
relative to each other, as long as they are all on before the computer is powered on.
Powering Down the MXI-Express 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. The order in which expansion
chassis are powered off, relative to each other, is not important.

Hardware Overview
This chapter presents an overview of MXI-Express hardware functionality
and explains the operation of each functional unit.
Functional Overview
MXI-Express is based on PCI Express technology. A MXI-Express kit
uses PCI Express switches to enable control of a PXI Express or
CompactPCI Express chassis from a PC with an available PCI Express slot.
The PCI Express switch architecture is transparent to device drivers, so no
additional software is needed to support using PXI Express and
CompactPCI Express devices in a chassis connected using MXI-Express.
Note The PXI Platform Services software on the PXI Platform Services CD or driver CD
included with your PXI Express MXI-Express hardware is required to provide chassis and
controller identification for PXI features such as trigger routing and slot detection. The PXI
Platform Services software is also included with the NI-DAQmx and NI-VISA drivers. For
more information, refer to KnowledgeBase 3TJDONDS at ni.com.
The link between the PC and the chassis is a x1 PCI Express link. This link
is a dual-simplex communication channel comprised of a low-voltage,
differentially driven signal pair. The link can transmit at a rate of 2.5 Gbps
in each direction simultaneously. This connector is not compatible with the
cabled PCI Express specification under development by the PCI-SIG.
Figure 3-1 shows the basic architecture of MXI-Express. The
NI PCIe-8361/8362 consists of a PCI Express x1 card edge connector, a
PCI Express switch, and one or two cabled MXI Express connectors. The
NI PXIe-8360 consists of one cabled MXI Express connector, a
PCI Express switch, and PXI Express connectors.

PCI Express x1 Card Edge Connector
The card edge connector allows you to use the NI PCIe-8361/8362 in a x1
or wider PCI Express slot in a PC. The PCI Express Card
Electromechanical Specification defines this connector.
PCI Express Switch
The PCI Express Base Specification defines a PCI Express switch as a
logical collection of PCI Express-to-PCI Express bridge devices. On the
NI PCIe-8361/8362, the upstream port of the switch is connected to the
PCI Express x1 card edge connector, and the two downstream ports are
connected to the two cabled MXI Express connectors.
On the NI PXIe-8360, the upstream part of the switch is connected to the
cable. One downstream port is connected to the SMBus Master, and either
4 x4 ports or 2 x8 ports are connected to the backplane, depending on the
chassis backplane configuration.

Chapter 3
Hardware Overview
Cabled MXI Express Connector
The cabled MXI Express connector provides all necessary signals to
connect an NI PCIe-8361/8362 and an NI PXIe-8360. These signals
include the PCI Express transmit and receive pair, the system clock,
presence detect signals, reset, and a wake-up signal. This connector is not
compatible with the cabled PCI Express specification being defined by the
PCI-SIG.
PCI Express-to-PCI Bridge
The PCI Express Base Specification defines a PCI Express-to-PCI bridge
as a device that connects a PCI Express fabric and a PCI hierarchy. On the
NI PXIe-8360, the PCI Express-to-PCI bridge connects the x1 PCI Express
link and an SMBus Master on the card.
SMBus Master
The SMBus is a low-speed bus for reading and configuring devices outside
the normal PCI Express mechanism. The PXI Express specification
requires controllers to supply an SMBus for reading chassis configuration
information from an EPROM. It may also be used for fan control, power
monitors, or other system devices. In addition, devices on plug-in boards
may connect to the SMBus for purposes specific to those devices.
LED Indicators
The LEDs on MXI-Express give status information about power supplies
and link state. The NI PCIe-8362 has two tri-color LEDs, one for each port
on the panel. The NI PXIe-8360 has two LEDs, one for power supply status
and one for link state.
The LEDs on the NI PCIe-8362 indicate the following:

Common Questions
This appendix lists common questions related to the use of the
MXI-Express controllers.
General Hardware
What are the board names of the MXI-Express remote controllers?
•
•
NI PCIe-8361/8362: PCI Express MXI-Express interface
NI PXIe-8360: PXI Express MXI-Express interface
How many PXI bus segments can I connect together with
MXI-Express?
The PCI specification allows up to 255 bus segments. MXI-Express does
not limit this number, but the maximum number of bus segments allowed
can be BIOS or operating system dependent. Also, a computer may already
have several PCI bus segments internally, and the MXI-Express link also
has multiple PCI buses internally. Every PCI Express device has at least
1 bus segment, though it will have more if it includes a bridge or switch.
What host PCs are compatible with MXI-Express for PXI Express?
Refer to KnowledgeBase 3U7CI4D8 at ni.com.
Note Due to the point-to-point nature of PCI Express, MXI-Express supports only the star
configuration. You must use traditional MXI for the daisy chain configuration.
General Cabling
What is the maximum length of a MXI-Express copper cable?
The maximum length for a MXI-Express copper cable is 7 m. National
Instruments offers 3 m and 7 m copper cables.

Common Questions
General Software
Under which operating systems will MXI-Express work?
MXI-Express will be recognized as a collection of PCI-to-PCI bridges to
the majority of operating systems. It should automatically work with most
systems like Windows, Macintosh OS X, Linux, and Solaris, but only
Windows XP has been verified in the initial release of MXI-Express.
What software is required to use my MXI-Express kit?
For Windows and LabVIEW RT, the required software is included as part
of the latest version of NI-VISA included with your kit. The software for
your MXI-Express controller enhances the product, allowing you to
view information about the organization of your PXI system and
programmatically retrieve data about the chassis and modules you have
installed.
If the MXI-Express software does not support your operating system,
you can still use MXI-Express and the operating system will provide a
mechanism for you to ignore the SMBus master that is built into the
MXI-Express hardware.
MXI-3 required optimization software. Does MXI-Express require
the same?
No. The necessary optimization is now done automatically by the
MXI-Express hardware.
How does my MXI-Express board show up in the Windows Device
Manager?
MXI-Express boards contain two types of PCI devices onboard and will
have several listings in the Windows Device Manager (WDM). The first
devices show up in the WDM listed under System devices as PCI standard
PCI-to-PCI bridges. The second device type shows up in the WDM as an
NI PXIe-8360 SMBus Controller when the correct MXI-Express driver is
installed. This second device provides configuration information about the
chassis. The NI PCIe-8361 includes two PCI standard PCI-to-PCI bridges.
The NI PCIe-8362 includes three PCI standard PCI-to-PCI bridges. The

Appendix B
Common Questions
NI PXIe-8360 includes five to seven bridges and one
NI PXIe-8360 SMBus Controller device.
If the MXI-Express software is not installed, the PCI-to-PCI function will
still be detected and work correctly, but the SMBus master will be detected
as an unknown device.
MXI-3 and MXI-4 to MXI-Express Upgrade Questions
What are some of the improvements from MXI-3 and MXI-4 to
MXI-Express?
MXI-Express incorporates the latest technology to include:
•
•
•
Support for PCI Express slots.
Support for PXI Express and CompactPCI Express chassis.
Improved error correction and handling for noisy or harsh
environments.
•
•
•
Improved mechanical connectivity.
Improved performance.
Support for two chassis from a single card in the host PC.
Can a MXI-3, MXI-4, and MXI-Express board be used together
directly?
No. MXI-3, MXI-4, and MXI-Express boards use different cable
connectors and cannot be connected together. Additionally, the
board-to-board communication protocols differ.
Can I use a MXI-3, MXI-4, and MXI-Express kit in the same
multichassis PXI system?
Yes. Different MXI kits can be intermixed to connect multiple PXI and
PXI Express chassis together. As mentioned previously, an individual
MXI-3 or MXI-4 board will not cable directly to a MXI-Express board.
MXI-3 and MXI-4 systems required the use of a specific boot ordering.
Is this a requirement with MXI-Express?
Yes. The requirements of the PCI bus still mandate that you must power-on
secondary PXI chassis before powering on the host PC when using
MXI-Express.

Appendix B
Common Questions
With MXI-3 and several chassis connected in series (daisy chain
configuration), you were required to power-on the chassis in order starting
with the chassis at the end of the chain and move towards the host
controller. Now with MXI-Express, multiple chassis are connected in
parallel and can be powered on in any order, except that you need to ensure
that the last component powered on is the host PC.
For more details, refer to the Powering Up the MXI-Express System section
of Chapter 2, Hardware Installation.
