VX1411 MainFrame Instruction Manual

Getting Started

Product Description

This chapter provides an overview of the VX1411 Mainframe. It includes installation and configuration information on user installed options.

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:

H Adequate available power for the majority of applications H Intelligent cooling for installed modules H High quality auto-configuration backplane H Optional adjustable rackmounts and cable tray

These features are explained in more detail in the following paragraphs.

Power Supply

Cooling

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 combinations 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.

VX1411 MainFrame Instruction Manual

1–1

Getting Started

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.

Backplane

Optional Rackmounts and

Cable Tray

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.

1–2

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 the rackmounts begin on page 1–10.

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.

Rackmount Installation

Install the Rackmount

Kit Hardware

The procedures for installing the rackmount kits are nearly identical 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 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:

H T-15 Torx Driver H T-20 Torx Driver H #2 Phillips Screw Driver

Refer to Figure 1–4 and perform the following steps to install the rackmount kit hardware:

1. Remove the rubber feet from the mainframe.

2. Determine whether you want to install the VX1411 Mainframe so that it

extends out of the rack or is recessed within the rack. If you want to extend the VX1411 Mainframe from the front of the rack,

position the rackmount bracket as shown on the right side of Figure 1–4. If you want to recess the VX1411 Mainframe in the rack, position the rackmount bracket as shown on the left side of Figure 1–4.

3. Determine how far you want to recess or extend the VX1411 Mainframe and

install the rackmount adapter as shown using two 8-32 screws (included with the kit). Similarly, install the other bracket on the other side of the mainframe.

NOTE. To comply with VXIplug&play mounting specifications, position the rackmount adapter at the mounting holes with the adjacent identifier keys (See Figure 1–4). This results in 3.960 inches (10.06 cm) from the module panel mounting surface to the rack frame mounting surface.

Getting Started

Install the Mainframe

in the Rack

Use the following procedure to install the VX1411 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 1–5.

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 1–5) 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 1–5. 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.

Configuration

Getting Started

After installing the mainframe you are ready to configure it for your applications. If you have not already done so, install your VXIbus modules in the mainframe following the installation guidelines for your VXIbus module.

NOTE. If some VXI modules do not install fully into the mainframe, it may be necessary to remove the shutter and spring from the card guide. For some double-wide modules it may be convenient to remove only one of the shutters instead of disassembling the shutter. To remove the card guides refer a qualified service person to Procedure 4: Removing the Card Guides beginning on page 6–9 in the Maintenance chapter.

Module Selection and

Design Guidelines

The VX1411 Mainframe is UL listed to UL 3111-1 and CAN/CSA C22.2 No. 1010.1 and is IEC 1010-1 compliant. You should use VXIbus modules with the mainframe that are listed or designed to limit electric shock and fire.

H Investigate the possibility of fire hazards due to the availability of power

from the mainframe exceeding 150 W per slot. Use similar considerations for VXIbus Modules that externally receive power greater than 150 W per slot.

H Printed wiring boards should be flame rated UL 94V–1 or better. H To prevent possible electrical shock, limit the voltage to the mainframe

interface or chassis to less than 60 VDC, 30 V

H Ensure that high voltage measuring inputs provide a means of limiting

unintended voltages that may reach the mainframe interface or chassis to less than 60 VDC, 30 V

Operating Basics

Fan Speed Control

The On/Standby switch on the top-left corner of the front panel applies DC voltages to the mainframe. The switch is a momentary contact switch. The switch is lighted when DC voltages are applied to the mainframe.

Figure 2–3 shows the rear view of the standard VX1411 Mainframe. The AC power connector is located on the bottom left side on the rear of the

mainframe. The AC fuse holder is located just above the power connector. The chassis ground screw (if installed) can be used to connect multiple

mainframes to a common ground point. The fan filter is located on the back of the mainframe. The filter slides easily into

the mainframe; there is no need to remove any covers to replace or clean the fan filter.

The Fan Speed switch controls the speed of the system cooling fans. When the switch is set to the low position, the fans are set to a low speed to reduce fan noise. When the switch is in the FULL position, the fans operate at full speed.

To maintain appropriate power supply cooling, set the fan speed switch according to Figure 2–2. For high module loads and high ambient temperatures, set the fan speed switch to full.

Glossary

The terms in this glossary are defined as used in the VXIbus System. Although some of these terms may have different meanings in other systems, it is important to use these definitions in VXIbus applications. Terms which apply only to a particular instrument module are noted. Not all terms appear in every manual.

ACFAIL*

A-Size Card

A VXIbus instrument module that is 100.0 × 160 mm × 20.32 mm (3.9 ×

6.3 in × 0.8 in), the same size as a VMEbus single-height short module.

Asynchronous Communication

Communications that occur outside the normal “command-response” cycle. Such communications have higher priority than synchronous communication.

Backplane

Interface Device

A VXIbus device that provides one or more interfaces to external equipment.

Interrupt Handler

A functional module that detects interrupt requests generated by Interrupters and responds to those requests by requesting status and identity information.

Interrupter

A device capable of asserting VMEbus interrupts and performing the interrupt acknowledge sequence.

IRQ

The Interrupt ReQuest signal, which is the VMEbus interrupt line that is asserted by an Interrupter to signify to the controller that a device on the bus requires service by the controller.

Local Bus

A daisy-chained bus that connects adjacent VXIbus slots.

Local Controller

The instrument module that performs system control and external interface functions for the instrument modules in a VXIbus mainframe or several mainframes. See Resource Manager.

Local Processor

The processor on an instrument module.

Glossary–4
