The VX1411A IntelliFrame Mainframe provides all VXIbus voltages at levels
necessary for most ATE applications. The power supply has a volt-ampere
capacity of 1186 VA, with 700 watts is usable by VXI instrument modules at any
one time (refer to Appendix A: Power Budget Worksheet). The mainframe
accommodates exclusively digital applications, exclusively analog applications,
or combinations of both.

The power supply plugs directly into the rear of the mainframe and has no cables
to disconnect. The power supply can easily be replaced in less than three
minutes, minimizing downtime. The power supply automatically sets the ranges
for the appropriate input voltage and frequency.

The VX1411A IntelliFrame Mainframe provides optimal cooling for all installed
modules. The mainframe is equipped with two efficient variable speed fans. The
fan speed can easily be manually switched from a low noise, variable speed to
full speed for maximum cooling. Fan speed varies with ambient air temperature:

H Minimum speed <20C
H Maximum speed >50C
H Variable speed from 20 to 50C

Getting Started

Air is exhausted at the sides of the mainframe, allowing you to safely 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. To prevent damage from over heating, 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. The fans can
be replaced without disassembling the entire mainframe.

Backplane

Optional Rackmounts and

Cable Tray

The VX1411A IntelliFrame 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. The backplane is installed with standard EMI DIN shields.

Full differential distribution of the CLK10 signals provides a clean timing source
for your VXIbus instruments.

You can order the VX1411A IntelliFrame 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 butch 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; instructions for the
rackmount kits begin on page 1–11.

Options and Upgrade Kits

Table 1–1 lists the VX1411A IntelliFrame Mainframe options and upgrade kits
that you can purchase and install separately. Contact your local Tektronix

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.

Site Considerations

Cable Tray Installation

The VX1411A IntelliFrame Mainframe is designed to operate on a bench or in a
rackmount environment. For proper cooling, allow at least 2 inches (5.1 cm) of
clearance on the rear and sides of the mainframe. Determine how you will use
your VX1411A IntelliFrame 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. To avoid personal injury, use care when lifting or moving the
mainframe to avoid personal injury while performing the installation proce­dures.

The IntelliFrameR mainframe comes a with a 0.75-inch cable access area on the
bottom of the mainframe. Use the following procedure to install your cable tray
option:

You will need a T-20 Torx and Phillips driver to install Options 1U or 2U.
Options 1U and 2U can be installed three different ways; without rails, with

rails, or with rails installed at 90
Figure 1–1 on page 1–7 and Figure 1–2 on page 1–8 show how to install

Both options come with butch plates to mount cable connectors at the rear of the

cable trays. The butch plate will not fit on Option 1U when the foot rails are not
used. 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.
