VX1411 MainFrame Instruction Manual 1–1
Getting Started
This chapter provides an overview of the VX1411 Mainframe. It includes
installation and configuration information on user installed options.
Product Description
The VX1411 Mainframe is a 13-slot, C-size, VXIbus Mainframe. It fully
complies with the VXIbus Specification 1.4 requirements and is VXIplug&play
compatible. The mainframe has the following features:
HAdequate available power for the majority of applications
HIntelligent cooling for installed modules
HHigh quality auto-configuration backplane
HOptional adjustable rackmounts and cable tray
These features are explained in more detail in the following paragraphs.
The VX1411 Mainframe provides all VXIbus voltages at levels necessary for
most ATE applications. The power supply has a volt-ampere capacity of 904 VA,
but only 500 watts is usable by VXI instrument modules at any one time (see
Appendix A: Power Budget Worksheet). The mainframe accommodates
exclusively digital applications, exclusively analog applications, or combina-
tions of both.
The power supply plugs directly into the rear of the mainframe and has no cables
to disconnect. Because of this, the power supply can easily be replaced in less
than three minutes, keeping downtime to a minimum. The power supply
automatically sets the ranges for the appropriate input voltage and frequency; no
mechanical switch is required to select the correct line voltage.
The VX1411 Mainframe provides optimal cooling for all installed modules. The
mainframe is equipped with two efficient 2 speed fans. The fan speed can easily
be manually switched from a low noise, low speed to high speed for maximum
cooling.
Air is exhausted at the sides of the mainframe allowing you to stack the
mainframe with other rackmount equipment. Additional equipment placed on or
positioned above the product will not restrict airflow nor will that equipment be
directly affected by exhaust air.

CAUTION. Make sure the ambient air temperature inside the rackmount enclosure
remains below 55C.
Cooling is not wasted on empty slots. IntelliGuides automatically direct air to
only those slots containing modules; empty slots are shut off. The mainframe
directs airflow across each installed module from the bottom to the top of each
slot. Baffles balance the airflow from the front to back and across occupied slots
in the mainframe.
You can easily remove the air filter from the rear of the mainframe within a
matter of seconds. The fans can be easily replaced without disassembling the
entire mainframe.
The VX1411 Mainframe has an auto-configuration, solid-state backplane that
uses electronic jumpers for the IACK and BUS GRANT signal lines. There are
no jumpers to move or install on the backplane. This results in a high quality
backplane that is ideal for ATE systems that must be reconfigured frequently.
Full differential distribution of the CLK10 signals provide a clean timing source
for your VXIbus instruments.
You can order the VX1411 Mainframe with user-installed rackmounts and cable
tray. The cable tray provides a means to conveniently route cables from the front
of the modules to the rear of the mainframe. Option 1U includes a 1.75-inch
connector plate. You can install Option 1U to provide a 1.75-inch, 2.5-inch, or
4.25-inch deep cable tray.
The rackmount adapters let you recess the mainframe from the front panel
mounting surface at specified depths from 0.735 inches to 5.735 inches in
0.5-inch increments. Similarly, you can configure the mainframe to extend out of
the front of the rack at specified depths (0.57 inches to 5.57 inches in 0.5-inch
increments).
You can install the rackmount kits along with the cable tray to provide vertical
cable access to easily route cables to instruments above or below the mainframe
while keeping lead lengths as short as possible.
You can also install an optional Lexan door with the rackmount kit.
NOTE. If you choose to extend the mainframe out of the front of the rack, the
mainframe cannot accept a door.
Instructions for installing the cable tray begin on page 1–6 and instructions for

Installation
This section describes the procedures to install your mainframe. It includes
procedures for installing the mainframe with the rackmount or cable tray options.
This section does not include specific procedures for installing modules in the
mainframe. Refer to your module documentation for information regarding the
module installation instructions.
The VX1411 Mainframe is designed to operate on a bench or in a rackmount
environment. For proper cooling, allow at least two inches (5.1 cm) of clearance
on the rear and sides of the mainframe. Determine how you will use your
VX1411 Mainframe and follow the appropriate installation instructions. If you
ordered your mainframe with the cable tray option and one of the rackmount
options, install the cable tray before installing the rackmount.
WARNING. Use care when lifting or moving the mainframe to avoid personal
injury while performing the installation procedures.
The VX1411 Mainframe comes a with 0.75-inch cable access area on the bottom
of the mainframe (1-inch with the feet installed for bench-top operation). You
can order the mainframe with an optional cable tray and install the cable tray
following the procedures in this section. The option comes with a butch plate to
mount cable connectors at the rear of the cable tray.
The cable tray option can be installed three different ways as shown in the
following illustrations. In each example, place the mainframe upside-down or on
one of the sides on a clean working surface and follow the instructions in the
illustrations. To install the cable tray you need a T-15 and a T-20 Torx Driver.
Figure 1–1 on page 1–7 shows how to install Option 1U to provide a cable tray
depth of 1.75 inches.
Figure 1–2 on page 1–8 shows how to install Option 1U to provide a cable tray
depth of 2.5 inches.
Figure 1–3 on page 1–9 shows how to install Option 1U to provide a cable tray
depth of 4.25 inches.
You can modify the butch plate to accept cable connectors at the rear of the
mainframe. Specific instructions for modifying the butch plate are not given
since the locations, types, and size of connectors vary with each application.
