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.

Front Panel SYSReset

Activation

Rackmount Installation

The IntelliFrameR mainframe provides you the ability to generate a backplane
SYSReset signal from the front panel. This feature allows you to reset the
complete VXI system without having to power down the mainframe. A
SYSReset activation is accomplished by pushing the right side (nonlighted side)
of the On/Standby power switch.

NOTE. If you decide to configure the front panel SYSReset, you should configure
the mainframe before installing the rackmount hardware. Refer to Appendix B:
Special Configuration Options for activation of this feature and then return to
this section to continue the installation procedures.

The procedures for installing the rackmount kits are similar for the Option 1R
and 2R kits. You can install the Option 1R kit to either recess the mainframe
from the front of the mainframe rack or to extend it out of the mainframe rack.
However, you can only install the door for the Option 2R kit so that the
mainframe recesses into the rack.

The steps for installing the rackmount kits consist of installing the rackmount
hardware to the mainframe, and then installing the mainframe in the rack.

You will need the following tools to install the rackmount options:

Install the Mainframe

in the Rack

Use the following procedure to install the VX1411A IntelliFrame Mainframe in
the rack:

1. Identify the right and left slide-out track assemblies: find the date code label

on each assembly. The assembly to be mounted in the left side of the rack

(the side nearest the left side of the mainframe when it is mounted in the

rack) has a date code that ends with LH (for left hand). The right assembly

has a date code ending with RH.

2. Measure the distance between the front and rear rail of the rack.

3. Align the rear bracket to the right slide-out track as shown in Figure 1–6.

Note that the rear bracket has two pairs of mount-through holes. When

aligning the bracket and the track, select a pair of holes that mount the rear

bracket so the flange-to-flange distance (see Figure 1–6) matches the front

rail to rear rail spacing that you just measured in step 2.

NOTE. If necessary, refer to the rackmount kit instructions for detailed installa­tion information.

4. Attach the rear bracket to the right slide-out track using two 10-32 screws

and a bar nut as shown in Figure 1–6. Leave the screws loose so that you can

adjust the overall length of the slide-out track assembly when installing the

mainframe in the rack.

5. Repeat steps 3 and 4 to assemble the left slide-out track assembly.

continue to slide the mainframe all the way back into the rack cabinet.

15. Tighten the four screws that you left loose at the rear of the rack when you

performed step 8 and pull the mainframe part way out of the rack. (Tighten
the 10-32 screws using 28 inch-lbs of torque.)

16. Be sure that the screws that you left loose at the front of the rack are loose

enough to allow the slide-out track assemblies to seek the normal positions.

17. Tighten the screws and push the mainframe all the way into the rack. If the

tracks do not slide smoothly, readjust the level using the method described in
steps 15 and 16. (Tighten the 10-32 screws using 28 inch-lbs of torque.)

18. Install the proper power cord at the rear of the mainframe.

NOTE. To ensure the mainframe is properly mounted in the rack do not tighten
the screws while installing the chassis track to the rack front rails. After all the
mounting screws have been installed shift the mainframe to the far right of the

Fan Speed Control

Operating Basics

The Fan Speed switch controls the speed of the system cooling fans. When the
switch is set to the variable position, the fans are set to a variable speed to reduce
fan noise. The fans are automatically adjusted by the mainframe to minimize fan
noise and provide appropriate cooling. When the switch is in the FULL position,
the fans operate at full speed.

The fans’ speed varies by the level of the ambient air temperature:

H Air temperatures less than 20C the fans operate at minimum speed
H Air temperatures between 0 to 50C the fans speed linearly increase with

temperature
H Air temperatures greater than 50C fans operate at full fan speed
The power supply is adequately cooled for any load condition when the fan

speed is placed in either the VAR or FULL speed position.

The VX1411A IntelliFrame Mainframe does not include diagnostics. The
functionality of the mainframe can be verified by following the performance
verification procedures as described in Functional Check and Performance
Verification beginning on page 1–22.

The mainframe has one line fuse. The line fuse can be one of three different
kinds depending on the operating voltage of the mainframe. Table 4–1 summa­rizes the different fuses that can be used as the line fuse in the mainframe.

Maintenance

Power Supply Problems. Use the following information to isolate power supply
problems to the power supply or to other modules:

H Isolate the problem to either the mainframe or to one of the installed VXIbus

Modules. Remove the modules from the mainframe and check that the
problem still exists.

H Try isolating the problem to a module by either replacing the module with an

known-good module or moving the module to a different slot.

H Check the fuses in the mainframe.
H Perform the procedures as described in Functional Check and Performance

Verification beginning on page 1–22 to verify the power supply voltages are
present and within the specified limits. If the voltages are not present,
replace the power supply. If any of the voltages are not within the specified
limits, replace the power supply.

Inadequate Cooling. If cooling problems occur, perform the following checks:

H Verify that the air filter is clean. If not, remove the air filter and clean it.
H One or both fans may not be operating properly. Check that both fans rotate.
H Verify that each fan is properly connected to the fan control module (see

H Check the power switch for proper function.
H Check that both fans are working at variable and high speeds.
H Verify that all of the empty slots within the mainframe are closed when no

H Verify that each VXIbus module has a front panel that activates the

Repackaging Instructions

If you need to send the VX1411A IntelliFrame Mainframe to a Tektronix field
center for repair, attach a tag to the mainframe with the owner name and address,
the serial number, and a brief description of the problem(s) encountered or the
service required. Always return all accessories so that the entire system can be
tested.

Figure 4–4 on page 4–7).

modules are installed. If necessary replace the faulty shutter assembly.

IntelliGuides (shutters).

When repacking the mainframe for shipment, use the original packaging. If the
packaging is unavailable or unfit for use, contact your local Tektronix representa­tive to obtain new packaging.

Theory of Operation

This section provides a brief overview of the theory of operation for the
VX1411A IntelliFrame Mainframe. Figure 4–12 shows the functional block
diagram of the mainframe and the major components.

The VX1411A IntelliFrame Mainframe contains the following major compo­nents:

H Power supply
H Backplane

Power Supply . The power supply provides all voltages and currents to the
mainframe. The power supply connects to the backplane at P25, P26, P27, and
P28. The power supply can be replaced as a single unit.

Backplane. The Backplane (A4) provides all the connections to module slots 0
through 12 in the mainframe. It also has connections to all other circuit boards
and modules in the mainframe.

The front panel On/Standby DC switch connects to J22 at the top of the
backplane.

The backplane connects to the Power Supply at J25 and J28. Connector P25
supplies power to the fans from the backplane via the fan control cable.

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
