System Controller Slot

The system controller slot is Slot 1 of the chassis and is a 4-Link
configuration system slot as defined by the CompactPCI Express and
PXI Express specifications. It has three system controller expansion slots
for system controller modules that are wider than one slot. These slots
allow the system controller to expand to the left to prevent the system
controller from using peripheral slots.

The backplane routes three PCI Express (PCIe) links of the system slot to
peripheral slots as x1 links. The other link of the system slot is routed as a
x4 link to the upstream port of a PCI Express switch that in turn provides
x1 PCIe links to the remaining peripheral slots. Refer to Figure 1-4 for
PCI Express and PCI connectivity.

By default, the system controller will control the power supply with the
PS_ON# signals. A logic low on this line will turn the power supply on.

© National Instruments 1-7 NI PXIe-1078 User Manual

Chapter 1 Getting Started

Note The Inhibit Mode switch on the backplane must be in the Default position for the

system controller to have control of the power supply. Refer to the Inhibit Mode Switch
section of Chapter 2, Installation and Configuration, for details about the Inhibit Mode
switch.

Hybrid Peripheral Slots

The chassis provides five hybrid peripheral slots as defined by the PXI-5
PXI Express Hardware Specification: slots 5-9. A hybrid peripheral slot

can accept the following peripheral modules:

• A PXI Express Peripheral with a x1 PCI Express link through the PCIe

• A CompactPCI Express Type-2 Peripheral with a x1 PCI Express link

• A hybrid-compatible PXI Peripheral module that has been modified by

• A CompactPCI 32-bit peripheral on the backplane’s 32-bit PCI bus

The hybrid peripheral slots provide PXI Express functionality (excluding
DSTAR and PXI Star) and 32-bit PXI functionality except for PXI Local
Bus. The hybrid peripheral slot only connects to PXI Local Bus 6 left and
right.

switch to the system slot

through the PCIe switch to the system slot

replacing the J2 connector with an XJ4 connector installed in the upper
eight rows of J2. Refer to the PXI Express Specification for details. The
PXI Peripheral communicates through the backplane’s 32-bit PCI bus.

PXI Express Peripheral Slots

There are three PXI Express peripheral slots: slots 2-4. PXI Express
peripheral slots can accept the following modules:

• A PXI Express peripheral with a x1 PCI Express link to the system slot

• A CompactPCI Express Type-2 peripheral with a x1 PCI Express link
to the system slot

PXI Local Bus

The PXI backplane local bus is a daisy-chained bus that connects each
peripheral slot with adjacent peripheral slots to the left and right.

The backplane routes PXI Local Bus 6 between adjacent PXI slots. The left
Local Bus 6 from slot 1 is not routed anywhere. The right Local Bus 6 from
slot 9 also is not routed anywhere.

NI PXIe-1078 User Manual 1-8 ni.com

Chapter 1 Getting Started

Local bus signals may range from high-speed TTL signals to analog signals
as high as 42 V.

Initialization software uses the configuration information specific to each
adjacent peripheral module to evaluate local bus compatibility.

PXI Trigger Bus

PXI Local Bus 6

PXI Trigger Bus

All slots share eight trigger lines.You can use these trigger lines in a variety
of ways. For example, you can use triggers to synchronize the operation of
several different PXI peripheral modules. In other applications, one module
can control carefully timed sequences of operations performed on other
modules in the system. Modules can pass triggers to one another, allowing
precisely timed responses to asynchronous external events the system is
monitoring or controlling.

System Reference Clock

The NI PXIe-1078 chassis supplies PXI_CLK10, PXIe_CLK100, and
PXIe_SYNC100 to every peripheral slot with an independent driver for
each signal.

An independent buffer (having a source impedance matched to the
backplane and a skew of less than 500 ps between slots) drives PXI_CLK10
to each peripheral slot. You can use this common reference clock signal to
synchronize multiple modules in a measurement or control system.

PXI_CLK10

PXIe_SYNC100

An independent buffer drives PXIe_CLK100 to each peripheral slot. These
clocks are matched in skew to less than 100 ps. The differential pair must
be terminated on the peripheral with LVPECL termination for the buffer to
drive PXIe_CLK100 so that when there is no peripheral or a peripheral that
does not connect to PXIe_CLK100, there is no clock being driven on the
pair to that slot.

An independent buffer drives PXIe_SYNC100 to each peripheral slot. The
differential pair must be terminated on the peripheral with LVPECL
termination for the buffer to drive PXIe_SYNC100 so that when there is no
peripheral or a peripheral that does not connect to PXIe_SYNC100, there
is no clock being driven on the pair to that slot.

PXI_CLK10, PXIe_CLK100 and PXIe_SYNC100 have the default timing
relationship described in Figure 1-6.

• Modification—Do not modify any part of the chassis from its original
condition. Unsuitable modifications may result in safety hazards.

Chassis Cooling Considerations

The NI PXIe-1078 chassis is designed to operate on a bench or in an
instrument rack. Regardless of the configuration, you must provide the
cooling clearances as outlined in the following sections.

Providing Adequate Clearance

Caution Failure to provide adequate clearances may result in thermal related failures in the

chassis or modules.

Apertures in the top, bottom, front, rear, and along the sides of the chassis
facilitate power supply and module cooling, as shown in Figure 2-2. Air for
module cooling enters through a fan intake in the bottom of the chassis. It
then exits through the upper sections at the right side and top, as shown in
Figure 2-1. Air for cooling the power supply enters the front and left side
of the chassis and exits through the rear of the chassis, as shown in
Figure 2-2.

Place the chassis on a bench top or in an instrument rack so that the fans
(air intakes) and the air outlet apertures along the right side, the top, and the
back of the chassis have adequate ventilation. Provide at least 44.5 mm
(1.75 in.) clearance above, behind, and on the sides of the unit for adequate
venting, as shown in Figure 2-3. High-power applications may require
additional clearance.

Chapter 2 Installation and Configuration

Chassis Ambient Temperature Definition

The chassis fan control system uses intake air temperature as the input for
controlling fan speeds when in Auto Fan Speed mode. Because of this, the
chassis ambient temperature is defined as the temperature that exists just
outside of the fan intake vent on the bottom of the chassis. Note that this
temperature may be higher than ambient room temperature depending on
the surrounding equipment and/or blockages present. You must ensure that
this ambient temperature does not exceed the rated ambient temperature as
stated in Appendix A, Specifications.

Setting Fan Speed

The AUTO/HIGH fan-speed selector switch is on the rear panel of the
NI PXIe-1078. Refer to Figure 1-2, Rear View of the NI PXIe-1078

Chassis, to locate the fan-speed selector switch. Select HIGH for maximum

cooling performance (recommended) or AUTO for quieter operation.
When set to AUTO, the chassis intake air temperature determines the fan
speed.

Installing Filler Panels

To maintain proper module cooling performance, install filler panels
(provided with the chassis) in unused or empty slots. Secure with the
captive mounting screws provided.

Installing Slot Blockers

You can improve the chassis cooling performance by installing optional
slot blockers. Refer to

ni.com for more details.

Rack Mounting

Rack mount applications require the optional rack mount kits available
from National Instruments. Refer to the instructions supplied with the rack
mount kits to install your NI PXIe-1078 chassis in an instrument rack.
Refer to Figure A-3, NI Chassis Rack Mount Kit Components.

Note You may want to remove the feet from the NI PXIe-1078 chassis when rack

mounting. To do so, remove the screws holding the feet in place.

NI PXIe-1078 User Manual 2-6 ni.com

Chapter 2 Installation and Configuration

Connecting Safety Ground

Caution The NI PXIe-1078 chassis is designed with a three-position inlet that connects the

cord set ground line to the chassis ground. To minimize shock hazard, make sure the
electrical power outlet you use to power the chassis has an appropriate earth safety ground.

Connecting to Power Source

Cautions Do not install modules prior to performing the following power-on test.

Installing Peripheral Modules

Caution The NI PXIe-1078 chassis accepts a variety of peripheral module types in

different slots. To prevent damage to the chassis, ensure that the peripheral module is being
installed into a slot designed to accept it. Refer to Chapter 1, Getting Started, for a
description of the various slot types.

This section contains general installation instructions for installing a
peripheral module in a NI PXIe-1078 chassis. Refer to your peripheral
module user manual for specific instructions and warnings. To install a
module, complete the following steps:

1. Inspect the slot pins on the chassis backplane for any bending or
damage prior to installation.

2. Connect the AC power source to the PXI Express chassis before
installing the module. The AC power cord grounds the chassis and
protects it from electrical damage while you install the module.

3. Ensure that the chassis is powered off.

4. Install a module into a chassis slot by first placing the module card
PCB into the front of the card guides (top and bottom), as shown in
Figure 2-6. Slide the module to the rear of the chassis, making sure that
the injector/ejector handle is pushed down as shown in Figure 2-6.

5. When you begin to feel resistance, push up on the injector/ejector
handle to fully seat the module into the chassis frame. Secure the
module front panel to the chassis using the module front-panel
mounting screws.

Power Inhibit Switch LED Indicator

The chassis power inhibit switch has an integrated LED. This LED
indicates one of two conditions:

• If the inhibit switch LED is steady green (not flashing), the chassis is
powered on and operating normally.

• If the inhibit switch LED is red, the system fans have failed.

Chapter 2 Installation and Configuration

Inhibit Mode Switch

On the NI PXIe-1078 backplane is a four-position DIP switch (SW1).
Switch 1 of SW1 controls the chassis inhibit mode. (Refer to Figure 2-7.)
In its default position (OFF), the PXI Express controller controls the power
supply on/off state based on the power switch on the chassis front panel.

Figure 2-7. Switch 1 of SW1

When switch 1 of SW1 is on, the backplane controls the power supply
on/off state. This allows you to circumvent the controller and turn the
chassis on or off manually. When switch 1 of SW1 is on, the power supply
turns on when the you press the front panel power switch. When the power
supply is on, holding down the front panel power switch for about
one second turns the power supply off.

Cautions Be careful to avoid damaging the backplane when accessing this switch.

o

Suddenly removing power from an operating controller may result in loss of data and
incorrect behavior on subsequent boots.

PXI Express System Configuration with MAX

The PXI Platform Services software included with your chassis
automatically identifies your PXI Express system components to generate

pxiesys.ini file. You can configure your entire PXI system and

a
identify PXI-1 chassis through Measurement & Automation Explorer
(MAX), included with your system controller. MAX creates the

pxiesys.ini and pxisys.ini file, which define your PXI system

parameters. MAX also provides an interface to route and reserve triggers so
dynamic routing, through drivers such as DAQmx, avoids double-driving
and potentially damaging trigger lines. For more information about routing
and reserving PXI triggers, refer to KnowledgeBase 3TJDOND8 at

ni.com/support.

The configuration steps for single or multiple-chassis systems are the same.
