FEATURES

PCIBX is a Hot Swap PCI, PCI-X extender card, compliant with PCI 2.2 specification. This extender card is able to isolate
voltages and signals to the UUT for Hot Swapping purposes via software control or the on-board mechanical switch. The
software interface is done with the system parallel port in order to not add any additi onal loading on the PCI signals and to
be able to control the extender from a different system than the one testing the UUT.

All PCI signals are switched during On/Off operation, except the JTAG signals which are routed straight through without
any isolation.

The On-Off may be controlled via mechanical switch or the software. The power control domination between the switch and
software is expl ained here:

On power up of the extender card, the extender can be controlled by the mechanical switch in the case where
software control is not available. Once the first software instruction is issued, the mechanical switch is disabled,
and the control of the extender is passed to the software.

In typical auto test applications it is suggested to leave the mechanical switch in the On position, so when the
system is powered up the BIOS can configure the PCI registers on the UUT. After the system has completed
booting user may issue SW commands (or continue to use the switch) to turn the power to the extender Off and
back On.

In addition to Hot Swapping the main voltages and signals, the PCIBX cards have the following features:

1) Short circuit protection

2) Software controllable +3.3Vaux.

3) Register to allow to reading of the status of the PME# signal.

4) On-board 3.3V source, 3 Amps

5) 5V ó 3V signal translators for DUT ó System, jumper selectable

6) I-to-V converters for +5V, +12V and +3.3V

7) ADC converter to read DUT voltages and current measurement

8) Board select jumper for multiple boards operation, 2 boards per system.

9) Selectable RST#, fixed 150 ms or programmable reset width from 2.5 us to 5 seconds

10) Registers to read the status of the RST#, 66 MHz enable, 32 bit or 64 bit operation and status of the UUT

power

11) Frequency counter for measuring the slot clock speed

12) Selectable power up +5V ramp, 50 us or 10 ms

13) Detection of the DUT not being fully asserted in the extender. This detection works by detecting if both pins

B3 and B57 are connected to GND. If both signals are connected to GND it is assumed that the UUT is seated
correctly in the top connector.

14) PCI-X power up initialization. This feature allows the user to define how the PCI-X signal is handled by the

extender. Options are UUT determines, forced to 66 MHz PCI-X or disabled. These option are selected by the
position of JP17.

INTRODUCTION

PCIBX Active Extender board isolates all signals and voltages to the Unit-Under-Test, when the On-Off switch is in the Off
position. All voltages are ramped down and ramped up during the power down and power up in order to eliminate any
spikes.

This board also allows voltage margin testing of the UUT, by allowing external power supplies to replace the system power
supplies as inputs to the Unit-Under-Test.

On-board current-to-voltage converters allow measurement of the current drawn by the UUT at any time, using just a
voltmeter, at the appropriate test points. On-board A/D also allows various current and voltage measurement via software
commands, see programming guide.

INSTALLATION

To install the Active Extender board, make sure to turn the PC power off. Insert the Active Extender in any available slot and
secure it’s bracket to the main chassis. You are now ready to use your new extender board.

OPERATION

In order to use the hot swap capability of these board you must use Catalyst software utility (PCIUD or PCIUW) available
our web site, http://www.getcatalyst.com, to read and write configuration registers. This software is available free of charge.
For an overview of these software packages see the Hot Swapping Utilities section of this manual.

ON-OFF

To insert or remove any Unit-Under-Test into and out of the Active Extender, make sure that the Active Extender is turned
Off, if the system power is to stay On. There are two ways to turn the Active Extender power On and Off. 1) The mechanical
toggle switch. 2) Software control.

Note: Once the software control is used the mechanical switch becomes disabled until next power cycle to the extender card.

The software control to the PCIBX boards is done via parallel port interface. Plug a parallel cable between the system port
running the software and the extender board(s) to turn the board(s) On and Off. Up to 2 PCIBX boards in a system may be
controlled independently, if so desired.

POWER-ON RESET

Each time the Active Extender board is turned Off and then On, a reset signal will be generated from the extender to the
Unit-Under-Test automatically. The duration of this reset is about 150 milliseconds. This reset time may be changed by
software up to 5 seconds. The reset to the Unit-Under-Test is also generated every time there is a reset from the bus.

2

CURRENT MEASUREMENT

Measurement may be taken using software commands or external voltmeter.

Voltmeter: To measure the current being drawn by the Unit-Under-Test, just connect a voltmeter to J3. Every Volt read by
the meter represents one Amp. So if the voltmeter reads 0.35, it represents that the Unit-Under-Test is drawing 350
milliampere of current. J3 terminals are marked for Ground, +5I, +3.3I and +12I.

NOTE: If the VIO and +5V are on the same plane on your board, you need to remove JP10 jumper, located on the extender
board, in order to get an accurate current measurement for the +5V.

Software: The voltage and current to the UUT may also be measured by software, please see instructions in the

"Programming Guide".

CURRENT LIMIT CIRCUITRY

Red LEDs, when illuminated, indicate a short or a very low voltage. Green LEDs when illuminated, indicate voltages at their
corresponding outputs. +5V, +12V, +3.3Vare electronically protected. +VIO and -12V are protected by resetable fuses.

INCREASE CURRENT LIMIT

1- To increase the +5V current limit remove the resistor at location R23 and follow the steps below.
A: To change the current limit to 8 Amps install a 10K resistor at location R22 and 6.2K resistor at location R23.
B: To change the current limit to 10 Amps install a 10K resistor at location R22 and 10K resistor at location R23.

2- To increase the +3.3V current limit the system must be supplying the +3.3V and not the on board regulator.
A: To change the current limit to 8 Amps install a 4.7K resistor on top of existing R57.

3

EXTERNAL POWER SUPPLY

An external power input terminal, J5, is used for the external power supply input. However, remember never to connect any
supply to these inputs so long as you have JP4, JP5, JP6 and JP7 installed. In case you want to use the external supply as
an input you must remove these 4 jumpers in order not to cause any conflict with the bus voltages. These jumpers are,
however, independent from each other. For instance if you would want to bring in only a +5V from the external supply and
continue to use the bus voltages for +12V, -12V, and +3.3V, you would only need to remove JP5. The list below identifies
which jumper is for which supply:

JP4 = -12V
JP5 = +5V
JP6 = +12V
JP7 = +3.3V

JP7 1-2 installed è 3.3V from on-board regulator
JP7 2-3 installed è 3.3V from the bus
JP7 not installed è 3.3V from the external supply

The following diagram indicates the interconnection of the Unit-Under-Test voltages to the bus voltages and the external
voltages:

+5VE ON-OFF 5V out to UUT

Circuitry

VIO to UUT

JP5 JP10

ON-OFF
Circuitry

+5V from the bus +VIO from bus

As indicated, there will be conflict in case the external supply is connected while the jumper is still in place. This circuit is
repeated for each of the 4 voltages.
If you are using external power supplies do not forget to connect the Ground (GND) signals between the system and the
supply. If your external power supply outputs are not isolated, make sure the ground of the PC (containing the extender
board) and the ground of the power supply are at the same voltage phase/level with respect to a common point, before
connecting the GND signal.

If making current measurements in +5V, be sure to remove JP10 if the VIO and +5V on your
board are on the same voltage plane.

LEDs

There are two sets of LED on the board, green and red. Each LED has a label which Voltage it represents. The green LED,
when lit, indicates presence of the corresponding voltage. The red LED, when lit, represent a short on the corresponding
voltage at the output. Please note that the green LEDs indicate presence of some voltage and do not necessarily indicate if
the exact voltage is at the expected level.

LED Purpose of LED
D10 -12V is present
D11 +12V is present
D12 +5V is present
D13 +3.3V is present
D18 +VIO is present
D9 -12V has a short or low voltage condition
D15 +12V has a short or low voltage condition
D14 +3.3V has a short or low voltage condition
D16 +5V has a short or low voltage condition

5V ó 3.3 V Translation

PCIBX is capable of allowing 5V UUT to work with 3.3V system and vice versa, without any timing degridation. Therefore
cards or components needing 3.3 V signaling can be tested or operated on a 5-volt system using these extender cards.

+5V cards can operate in +3.3V systems provided that +5V is provided to the UUT cards.

If JP3 is installed the UUT signals will be the same as the bus signals, most likely +5V.
If JP3 is not installed the signals between the bus and the UUT will be translated.

Hot Swapping Utilities

Features

• Hot Swap PCI Boards Under Test

• Reload configuration space data without rebooting the computer.

• Automate board testing for production applications

• Software control of Extenders, for hands off power cycling of Unit Under Test

• View & change configuration registers.

Overview

The purpose of this document is to provide the user with the knowledge and application of Hot Swap utility software
and extender cards for purposes of swapping PCI cards while the system power stays on. These utilities will allow the
user to perform var ious functions with the Catalyst Enterprises, PCI Active extenders. The software allows the user to
read, save and reload the configuration space data and allow the user to control the power of to the UUT during testing
via the test program.

Utility Programs

1. PCIUD: This DOS program allows the users of MS -DOS to read, save and reload (after the BIOS has already

configured the UUT at boot up) the configuration space data for PCI Devices. This program is useful if the user
needs to swap out the UUT, and continue to test the UUT, in MS -Dos. Please note that the configuration space
data for each device is slot specific. For more details please refer to the PCIUD document located on our website

http://www.getcatalyst.com on the Documents page.

2. PCIUW: This Windows program allows the users of Windows 95/98/ME and Windows NT/2000/XP, to read,

save and reload (after the BIOS has already configured the UUT at boot up) the configuration space data for PCI
Devices. This program is useful if the user needs to swap out the UUT, and continue to test the UUT, in Windows.
Please note that the configuration space data for each device is slot specific. For more details please refer to the
PCIUW document located on our website http://www.getcatalyst.com on the Documents page.

3. PARALLEL: This program allows the user to control the ON/OFF of the PCIBX extenders via the Parallel Port,

under Windows only. This program is useful when the user wishes to automate the power cycling of the PCIBX.
(The parallel port is used to control the On-Off power of the extenders to minimize the loading effect on the PCI
Signals to UUT). For more details please refer to the Parallel document located on our website

http://www.getcatalyst.com on the Documents page.

4. Driver file for Windows NT/2000/XP: This driver is required for user of Windows NT/2000/XP. This

driver provides a software interface between the Windows NT/2000/XP Operating System and the computer's
Parallel Port.

To Get Started Using the Hot Swapping Software

NOTE:

Please note that the utility programs provided here only read and write the configuration space data
to UUT and do not actually assign these parameters.

On system power up the BIOS has to do the assignment and initialization of the configuration
registers before the utility progr ams may be used.

At Power Up

Before the software in this package can be used, the following steps must be performed:

1. Power Down the Computer, remove the cover, and install the PCI Extender in a PCI Slot.

2. Install the UUT on top of the extender and be sure that the On-Off switch on the extender is in the On position.

3. Power on the computer and allow the system to go through boot.

4. When the computer has finished booting, verify that the UUT is working properly by executing your application.

5. If the UUT is working properly, you can proceed using the software provided in this package, please see the

section on Operating Instructions for PCIUW or PCIUD.

6. If the UUT is not working properly, refer to the troubleshooting guide section of this document.

Production Automation

PCI Test I/F Package

• Hot Swap up to 2 UUT boards on an enclosed system

• Low cost, easy to replace Connectors

• Designed to be used with the PCIBX.

• May be used in test environments where it is not desirable to leave the PC Chassis open.

• LEDs provide visual indication of UUT power.

• Easy automation of the power up and power down cycles, through software control.

• Minimizes the extender board connector wear -out.

• This fixture is designed for a 6" high PC Chassis, the user must cut a hole in the top cover of the chassis. This fixture

will connect to the installed PCIBX extenders, via a provided adapter PCIMM. After the fixture is installed the PC cover
may be installed again.

Troubleshooting Guide

UUT works when plugged directly on the motherboard, but does not work when plugged on top of a PCI Extender.

Assuming the PCI extender is in good condition and has not been damaged, this condition occurs on motherboards

where the IDSEL line is connected to an address line through a resistor larger than ~ 51 ohms. To verify this move

the extender and UUT to another machine with a different type of motherboard, if the UUT works on the second

system, the problem is the IDSEL line on the first system. You can also find the resistor for the IDSEL and measure

it by an Ohmmeter. This resistor is usually right next to the IDSEL pin next to each connector.

UUT stops working after cycling the p ower switch of the extender, but when the PC is booted with the UUT on top

of the extender, the UUT works fine.

The reason the UUT stopped working, is that the UUT has lost the configuration data when the PCI Extender was

powered down. To solve this probl em you must use the PCIUD or PCIUW software to read, save and reload the

configuration data.

Computer crashes when the extender power switch is cycled OFF and then ON, with UUT installed in top

connector of extender.

This condition can occur if any of the following conditions exist:

A. Devices on the UUT require a special timing sequence at the time of power up,

Check the devices on the UUT to determine if it contains a PCI Controller or other Bridge Chips. If it does,
install a 22 uF Capacitor between Pin 3 of U13 and GND. This capacitor will slow down the time between
when the +5V goes high and the time the Chip enable is driven low.

B. Some of the control signals of the PCI device on the UUT may be noisy or have glitches during power up.

This may be corrected in most cases by providing pull up on these signals. PCIBX has these pull ups but
other extenders do not.

With the UUT installed on top of the extender use a scope to check the signals SERR#, DEVSEL#, LOCK#,
FRAME#, TRDY# and STOP#, as the extender power switch is cycled, see if any of these signals spike
below 2V and then return to 3.3V.

C. The extender is damaged.

Several different UUT cards may be tested on an extender to see if all cards cause a system crash (which
points to the extender) or the problem is depended on any specific type of UUT.

Computer crashes when the extender power switch is turned OFF.

A. This can occur if the ICs on the extender card have been damaged and have internal leakage, This leakage

can cause some of the signals to be shorted to ground, VCC, or to each other.

B. The UUT is being used, by the system software, at the time the extender power switch is turned off the

software is looking for the board and system hangs when it can not find the UUT board.

Computer crashes when the extender power switch is in the OFF position and a new UUT is inserted.

This can occur if the extender card is damaged, and some of the signals are not fully turned off.
