Using the SYM22902

Low Profile PCI Host

Adapter

This chapter describes the SYM22902 Low Profile PCI Host Adapter

interface to PCI computer systems and includes these topics:

•

Section 1.1, “General Description,” page 1-1

Section 1.2, “Features,” page 1-2

Section 1.3, “Benefits of LVD Link™,” page 1-5

Section 1.4, “TolerANT® Technology,” page 1-6

1.1 General Description

The LSI Logic Symbios^®SYM22902 PCI to Ultra2 SCSI Dual Channel

Low Profile PCI Host Adapter provides two SCSI-3, Ultra2 SCSI

interfaces to PCI computer systems that require BIOS support on the

add-in SCSI adapter. Installing this adapter in your PCI system allows

connection of SCSI devices over a SCSI bus.

The SYM22902 host adapter provides two independent Ultra2 SCSI

channels. The external channel on the SYM22902 board supports Low

Voltage Differential (LVD) and Single-Ended (SE) SCSI, while the internal

channel supports LVD SCSI only. The SYM22902 is a SCSI solution for

an 1U and 2U size server. This board can support legacy fast SCSI

devices, Ultra SCSI devices, and the newest Ultra2 SCSI devices on the

appropriate connections.

The Symbios Storage Device Management System (SDMS™) software

operates the board. The design of the board does not prevent other SCSI

software from being used with it. BIOS support for this host adapter is

incorporated on the board in a 128K Flash device.

This guide and the LSI Logic Symbios PCI Storage Device Management

System SDMS 4.0 User’s Guide contain product information and

Symbios SYM22902 PCI to Ultra2 SCSI Dual Channel Low Profile PCI Host Adapter

installation instructions to help you gain the full benefits of your

SYM22902 PCI to Ultra2 SCSI Dual Channel Low Profile PCI Host

Adapter.

1.2 Features

This section provides an overview of the PCI Interface, the SCSI

Interface, and Board Characteristics for the SYM22902 host adapter

board.

1.2.1 PCI Interface

The PCI interface operates as a 32-bit or 64-bit DMA bus master, where

the connection is made through the J1 edge connector. The PCI portion

of the SYM53C896 Dual Channel Ultra2 controller is powered from the

host system PCI + 3.3 V power rail. The implementation is PCI 2.2

compliant.

The PCI interface includes these features:

•

Supports 64-bit or 32-bit (33 MHz) DMA bus master

Bursts 2 to 128 Dwords across PCI bus

Prefetches up to 8 Dwords of SCRIPTS™ instructions

Supports PCI Write and Invalidate, Read Line, and Read Multiple

commands

•

Provides zero wait-state bus master data bursts

Includes PCI Universal 3.3 V/5 V bus support

1.2.2 SCSI Interface

The SCSI interface is made through connector J2 for Channel A and J4

for Channel B. Connector J2 is a 68-pin VHDCI right-angle receptacle

that protrudes through the Low Profile PCI or Standard ISA/EISA bracket.

Connector J4 is a 68-pin high density receptacle, either right-angle

nonlatching or vertical with/without latches, for internal SCSI connection.

See Figure 2.1 for the location of these connectors.

1-2

Using the SYM22902 Low Profile PCI Host Adapter

The SCSI interface includes these features:

•

Provides two independent wide Ultra2 SCSI channels

Provides two connectors:

68-pin VHDCI for the external Channel A (LVD/SE)

68-pin high density for the internal Channel B (LVD)

•

Supports SE and LVD signaling: 16-bit SE or LVD interfaces

Supports LVD/SE termination for external Channel A and LVD

termination for internal Channel B

•

Supports fast, Ultra, and Ultra2 data transfer capability: Ultra2 SCSI

LVD synchronous transfers are as fast as 80 Mbytes/s

Supports three termination control options:

–

Keep termination always on

Use a manual shunt on each channel to disable termination

Provide software control using GPIO3 and/or manual shunt to

enable or disable the terminators

•

Supplies SCSI termination power (TERMPWR) source with

autoresetting circuit breaker

•

Includes SCSI Plug and Play

Provides flash EEPROM for BIOS storage for each channel

Includes 8 Kbytes internal RAM for SCRIPTS instruction storage for

each channel

•

Provides a SCSI activity LED connector (J3) for both channels

1.2.3 Board Characteristics

This board provides a low cost Low Profile PCI (LPPCI) solution for

computer manufacturers that require BIOS support for their add-in SCSI

host adapters. The board characteristics are:

•

PCI board dimensions

Approximately 6.60 x 2.53 inches

•

Universal 64-bit PCI card edge connector

Low Profile PCI and Standard ISA/EISA bracket

Features

1-3

1.2.4 SCSI Activity LED Interface

The SYM22902 LED interface is a four-wire arrangement that allows the

user to connect an LED harness to the board. The GPIO0_FETCH line

for each channel is driven low to complete the circuit when a harness

with an LED is attached. The connector on the SYM22902 is J3 for both

channels. See Table A.5 for the signal name and pin numbers for this

LED interface.

1.2.5 Wide Ultra2 SCSI

The SYM22902 fully supports Wide Ultra2 SCSI. This interface is an

extension of the SCSI-3 family of standards that expands the bandwidth

of the SCSI bus to allow faster synchronous data transfers, up to 80

Mbytes/s. Wide Ultra2 SCSI provides a doubling of the data rate over the

Ultra2 SCSI interface, while it increases cable lengths and allows a larger

number of devices on the cable than Ultra2 SCSI interfaces.

Special SCSI cables are specified for operation with Wide Ultra and

Ultra2 SCSI devices. You must consider the total number of devices and

the length of your SCSI bus when setting up your system. See Chapter 2,

“Installing the SYM22902 Host Adapter” for a more detailed explanation

of SCSI bus connections.

The cable included in the SYM22902 host adapter kit is matched for

fast/Ultra/Ultra2 SE or LVD operation. This cable also has built-in LVD

termination since most Ultra2 hard disk drives are not made with on-

board LVD termination. Table 1.1 provides an overview of standard SCSI

cable specifications.

1. This parameter may be exceeded in point-to-point and engineered

applications.

2. LVD was not defined in the original SCSI standards for this speed. If

all devices on the bus support LVD, then 12-meter operation is

possible at this speed. However, if any device on the bus is SE only,

then the entire bus switches to SE mode, and the distances in the

SE column apply.

3. SE and high power differential are not defined at Ultra2 speeds.

1.3 Benefits of LVD Link™

The SYM53C896 supports LVD for SCSI, a signaling technology that

increases the reliability of SCSI data transfers over longer distances than

are supported by SE SCSI. The low current output of LVD allows the I/O

transceivers to be integrated directly onto the chip. LVD provides the

reliability of HVD SCSI without the added cost of external differential

transceivers. Ultra2 SCSI with LVD allows a longer SCSI cable and more

devices on the bus, with the same cables defined in the SCSI-3 Parallel

Interface standard for Fast-20 (Ultra SCSI). LVD provides a long-term

migration path to even faster SCSI transfer rates without compromising

signal integrity, cable length, or connectivity.

For backward compatibility to existing SE devices, the SYM53C896

features universal LVD Link transceivers that can support LVD SCSI, SE,

and HVD modes. The LVD Link technology also supports HVD signaling

in legacy systems, when external transceivers are connected to the

SYM53C896. This allows the SYM53C896 to be used in both legacy and

Ultra2 SCSI applications.

Benefits of LVD Link™

1-5

®

1.4 TolerANT Technology

The SYM53C896 features TolerANT technology, which includes active

negation on the SCSI drivers and input signal filtering on the SCSI

receivers. Active negation causes the SCSI Request, Acknowledge,

Data, and Parity signals to be actively driven HIGH rather than passively

pulled up by terminators. Active negation is enabled by setting bit 7 in

the SCSI Test Three (STEST3) register. Refer to the LSI Logic Symbios

SYM53C896 PCI to Dual Channel Ultra2 SCSI Multifunction Controller

Technical Manual for specific register information.

TolerANT receiver technology improves data integrity in unreliable

cabling environments, where other devices would be subject to data

corruption. TolerANT receivers filter the SCSI bus signals to eliminate

unwanted transitions, without the long signal delay associated with

RC-type input filters. This improved driver and receiver technology helps

eliminate double clocking of data, the single biggest reliability issue with

SCSI operations. TolerANT input signal filtering is a built-in feature of the

SYM53C896 and all LSI Logic fast SCSI, Ultra SCSI, and Ultra2 SCSI

devices.

The benefits of TolerANT technology include increased immunity to noise

when the signal is going HIGH, better performance due to balanced duty

cycles, and improved fast SCSI transfer rates. In addition, TolerANT SCSI

devices do not cause glitches on the SCSI bus at power-up or

power-down, so other devices on the bus are also protected from data

corruption. When it is used with the LVD Link transceivers, TolerANT

technology provides excellent signal quality and data reliability in real

world cabling environments. TolerANT technology is compatible with both

the Alternative One and Alternative Two termination schemes proposed

by the American National Standards Institute.

Installing the SYM22902

Host Adapter

This chapter provides instructions on how to install the SYM22902 host

adapter board and includes these topics:

•

Section 2.1, “Quick Installation Procedure,” page 2-1

Section 2.2, “Detailed Installation Procedure,” page 2-3

Section 2.3, “Completing the Installation,” page 2-23

2.1 Quick Installation Procedure

This section provides an overview of the installation procedure. If you are

an experienced computer user with prior host adapter installation and

SCSI bus setup experience, this section may sufficiently describe the

procedure for you. If you prefer a more detailed guidance for installing

the SYM22902 host adapter, proceed to Section 2.2, “Detailed

Installation Procedure.”

For safe and proper installation, check the user’s manual supplied with

your computer and perform the following steps.

Step 1. Ground yourself before handling the host adapter board.

Step 2. Remove the SYM22902 from its packing and examine it for any

damage.

An example of this host adapter board is shown in Figure 2.1.

A more detailed drawing is located in Figure A.1.

Step 3. Switch off and unplug the system.

Step 4. Remove the cabinet cover on your computer to access the PCI

slots.

Caution:

Ground yourself by touching a metal surface before

handling boards. Static charges on your body can damage

Symbios SYM22902 PCI to Ultra2 SCSI Dual Channel Low Profile PCI Host Adapter

2-1

electronic components. Handle plug-in boards by the edge;

do not touch board components or gold connector contacts.

The use of a static ground strap is recommended.

Step 5. Locate the PCI slots on your computer.

A 32-bit slot may be used but full performance requires a 64-

bit slot. Refer to the user’s manual supplied with your computer

to confirm the location of the PCI slots. The SYM22902

requires a PCI slot that allows bus master operation. See

Figure 2.2.

Step 6. Remove the blank bracket panel on the back of the computer

aligned with the PCI slot you intend to use.

Save the bracket screw for securing the installed board.

Step 7. Carefully insert the edge connector J1 of the host adapter into

the PCI slot.

Make sure the edge connector is properly aligned before

pressing the board into place. The bracket around connector J2

should fit where the blank bracket panel was removed.

Note:

You may notice that the components on a PCI host adapter

face the opposite way from non-PCI adapter boards you

have in your system. This orientation is correct. The board

is keyed and will only go in one way.

Step 8. Secure the bracket with the bracket screw before making the

internal and external SCSI bus connections.

Step 9. If you are connecting any internal SCSI devices, plug a 68-pin

connector on the end of the internal SCSI ribbon cable into

connector J4 (see Figure 2.1).

Be sure you match pin 1 on both connectors.

Step 10. Chain the internal SCSI devices on this cable.

Step 11. Connect the LED cable if desired.

This is designed to drive an off-board system LED and

indicates activity on the SCSI bus. The off-board LED will

operate at the same time as the on-board SCSI Activity LED.

Step 12. Replace the cabinet cover as described in the user’s manual for

your computer.

Step 13. Make all external SCSI bus connections.

2-2

Installing the SYM22902 Host Adapter

Step 14. Refer to the LSI Logic Symbios PCI Storage Device

Management System SDMS 4.0 User’s Guide (or the guide for

the software you will use) to load the driver software for your

2.2.4 Connecting SCSI Peripherals

All internal SCSI bus connections to the SYM22902 host adapter can be

made with an unshielded, 68-conductor ribbon cable (see Figure 2.3).

One side of this cable is marked with a color to indicate the pin-1 side.

The connectors on this cable are keyed to ensure proper pin-1

connection. Use Ultra/Ultra2 rated cables for these bus speeds. (See

Table 1.1.)

All external SCSI bus connections to the SYM22902 host adapter are

made with shielded, 68-conductor cables (see Figure 2.3). The

connectors on this cable are always keyed to ensure proper pin-1

connection. Some internal cables come with a LVD/SE emulator on one

end. This end should be furthest from the host adapter.

Most PC cabinets are designed with a front panel LED to

indicate bus activity. It may already be connected to an existing

IDE controller. If you want, you can connect the LED to the

SCSI LED connector.

Detailed Installation Procedure

2-11

Step 4. Connect the LED cable to J3 on your SCSI host adapter, as

shown in Figure 2.8.

The Busy LED connector J3 is not keyed. The J3 connector is

a 4-pin one row right-angle header for both Channel A and

Channel B. Some LED cables have only two wires. In this case,

place the connector on one end of J3. If the LED does not light

during SCSI bus activity, you may have to rotate the LED cable

180° on J3 or move it to the other end of the jack.

After the correct connection is established, the front panel LED

will indicate activity on the SCSI bus. There is also an LED on

the SYM22902 host adapter board that indicates activity on the

SCSI bus.

See Table A.5 for connector pin out information.

2.2.4.2 Making External SCSI Bus Connections

This section provides step-by-step instructions for making external SCSI

bus connections.

Step 1. Plug the 68-pin VHDCI connector on one end of a shielded

external high density cable (see Figure 2.3) into the host

adapter connector J2.

This connector is exposed on the back panel of your computer.

Figure 2.9 shows where this connection is made.

Figure 2.9 External Cable to Host Adapter

Detailed Installation Procedure

2-13

Step 2. Plug the 68-pin connector on the other end of the shielded

external SCSI cable into the SCSI connector on your external

SCSI device.

An example of this connection is shown in Figure 2.10.

Figure 2.10 External Cable to External SCSI Device

2-14

Installing the SYM22902 Host Adapter

Step 3. Chain any additional SCSI devices together with shielded

external SCSI cables.

See the example in Figure 2.11.

Figure 2.11 Multiple External SCSI Devices Chained Together

Detailed Installation Procedure

2-15

2.2.5 SCSI Bus Termination

The devices making up the SCSI bus are connected serially (chained

together) with SCSI cables. The first and last physical SCSI devices

connected on the ends of the SCSI bus must have their terminators

active. All other SCSI devices on the bus must have their terminators

removed or disabled.

Termination control has three build options to allow three modes of

termination. The three options are:

•

Termination is always on.

Termination can be disabled by placing a manual shunt over both

posts on each channel. When the shunt is off, the terminator is

active. When the shunt is on both posts, the terminator for that

channel is disabled.

•

Termination can be enabled or disabled for a specific channel using

software control with GPIO3 and/or the manual shunt method.

LVD peripheral devices are normally terminated with external

terminators, but are sometimes set with jumpers or with a switch on the

peripheral. Refer to the peripheral manufacturer’s instructions and to the

user’s manual for your computer for information on how to identify the

terminator setting of each device and how to change it.

2-16

Installing the SYM22902 Host Adapter

The SYM22902 automatically controls SCSI bus termination for two

different bus configurations, depending on the use of the SCSI channel

(see Figure 2.1). The two bus configurations are:

•

Termination on

Termination off

You can disable termination in two ways:

•

Use BIOS software control, where the BIOS termination option is

changed from Auto to Off.

Manually place Channel A shunt DIS_A and Channel B shunt DIS_B

on both posts of their respective jumpers.

2.2.5.1 Internal SCSI Terminations

If you are making internal SCSI device connections on your host adapter,

you must terminate the last internal device on the SCSI bus. You must

disable the termination on all other devices. Termination on your host

adapter is automatically enabled in this case.

Figure 2.12 shows an example of how termination is determined for this

SCSI bus configuration.

Detailed Installation Procedure

2-17

Figure 2.12 Internal SCSI Device Termination

2.2.5.2 External SCSI Terminations

If you are making external SCSI device connections on your host

adapter, you must terminate the last external device on the SCSI bus.

2-18

Installing the SYM22902 Host Adapter

Termination on all other devices must be disabled. Termination on your

host adapter is automatically enabled in this case.

Figure 2.13 shows an example of how termination is determined for this

SCSI bus configuration on your host adapter Channel B.

2.2.6 Setting SCSI IDs

You must set each SCSI device and the host adapter to a separate SCSI

ID. The IDs are 0 through 7 for an 8-bit bus and 0 through 15 for a 16-

bit bus. SCSI ID 7 is the preset host adapter setting, giving it the highest

priority on the SCSI bus. If you plan to boot your computer from a hard

disk drive on the SCSI bus, that drive should have SCSI ID 0, or the

lowest SCSI ID on the bus. Chapter 3, “Configuring the SYM22902 Host

Adapter” explains how to set your host adapter ID using the Symbios

SCSI BIOS Configuration Utility.

The peripheral device SCSI IDs are usually set with jumpers or with a

switch on the peripheral. Refer to the peripheral manufacturer’s

instructions and to the user’s manual for your computer to determine the

ID of each device and how to change it. No duplication of SCSI IDs is

allowed on a SCSI bus.

Note:

As SCAM (SCSI Configured AutoMatically) support is off by

default for the SYM53C896 Version 4.11.00 and above, you

may choose to turn this on to assist in assigning SCSI IDs.

Step 1. Determine the SCSI ID of each device on the SCSI bus.

Note any duplications.

Step 2. Make any necessary changes to the SCSI IDs and record the

IDs for future reference. Correct any duplications at this time.

Table 2.1 on page 2-21 is provided as a place to keep this

record.

2.2.7 Setting Interrupts

Normally, you do not change the default interrupt routing for the

SYM22902, since performance is usually increased by having two

separate interrupts. However, if your system does not support two

separate interrupts, the INTA/INTB jumper (see Figure A.1) is provided to

change the interrupt routing. Table 2.2 explains the jumper settings.

Section 3.1, “Overview of the SCSI BIOS Configuration Utility,”

page 3-1

•

Section 3.2, “Starting the Configuration Utility,” page 3-2

Section 3.3, “The Symbios SCSI BIOS Configuration Utility Menus,”

page 3-3

•

Section 3.4, “Exiting the SCSI BIOS Configuration Utility,” page 3-19

3.1 Overview of the SCSI BIOS Configuration Utility

The SYM22902 host adapter is loaded with Symbios SCSI BIOS and

Configuration Utility Version 4.16. This chapter describes the process

you need to follow to change the configuration settings on your board.

34.732 pc

The SDMS SCSI BIOS provides support for the BIOS Boot Specification

(BBS), which allows you to choose which device to boot from by

selecting the priority.

To use this feature, the system BIOS must also be compatible with the

BBS. If your system supports the BBS, then you will use the system

BIOS Setup Menu to select the boot and drive order. In the system BIOS

setup, the Boot Connection Devices Menu appears with a list of available

boot options. Use that menu to select the device and rearrange the order.

Then exit to continue the boot process.

In most cases, you should not need to change the default configuration

of the host adapter. You may decide to alter these default values if there

is a conflict between device settings or if you need to optimize system

performance.

There are four sets of configurations you can change. You make changes

on subordinate menus called from the Main Menu, which is opened when

you start the SCSI BIOS Configuration Utility. The subordinate menus are

listed below.

Device Properties

Boot Adapter List

Global Properties

All these properties are controlled by menus you access through the

configuration utility through the Main Menu. The Main Menu also gives

an overview of some properties of installed Symbios host adapter

boards.

3.2 Starting the Configuration Utility

You can see the version number of your Symbios SCSI BIOS in a banner

displayed on your computer monitor during boot. If the utility is available,

the following message also appears on your monitor:

44.25 pc

Press Ctrl-C to start Symbios Configuration Utility...

This message remains on your screen for about five seconds, giving you

time to start the utility. If you decide to press “Ctrl-C,” the message

changes to:

Please wait, invoking Symbios Configuration Utility...

After a brief pause, your computer monitor displays the Main Menu of the

Symbios SCSI BIOS Configuration Utility.

These messages may appear during the boot process:

•

“Adapter removed from boot order, parameters will be

updated accordingly” appears when an adapter is removed from

the system or relocated behind a PCI bridge.

•

“Configuration data invalid, saving default

configuration!” appears if none of the information in the NVRAM

is valid.

order and more adapters exist than are shown.

NonVolatile Random Access Memory (NVRAM) is available on the

SYM22902 host adapter. Changes can be made and stored using this

menu driven utility.

Important: This utility is a powerful tool. If, while using it, you somehow

disable all of your controllers you can recover. Pressing

Ctrl-E after memory initialization during a reboot allows you

to re-enable and reconfigure.

Note:

Not all devices detected by the SCSI BIOS Configuration

Utility can be controlled by the BIOS. Devices such as tape

drives and scanners require that a device driver specific to

that peripheral be loaded. This device driver is provided by

the device manufacturer.

^{44.25 pc}3.3 The Symbios SCSI BIOS Configuration Utility Menus

This section describes the menu system of the Symbios SCSI BIOS

Configuration Menu System.

3.3.1 Using the Menus

You make your configuration changes in the main area (central portion)

of the menu. As in the example menus shown in the figures, it is lighter

in color than the header or footer areas on the top and bottom of the

menu. The commands you use to make changes are shown in the footer

area and described in Table 3.1. Settings with black text can be changed,

while settings with white text cannot. This is true regardless of whether

the Color or Mono setting is chosen in the Global Properties Menu

(Figure 3.6), which is described in Section 3.3.6, “Global Properties

Menu”.

devices attached that are shared with one or more

other adapters and therefore, the Symbios SCSI

BIOS should avoid SCSI bus resets as much as

possible.

This option allows the user to enable an adapter to

join a cluster of adapters without doing any SCSI bus

resets. This is a requirement for Microsoft Cluster

Server. The default value is No with an alternate

option of Yes.

Description

Scan LUNs > 0

Configuration

[Yes / No]

Indicates whether to scan for LUNs greater than zero for

a device. LUN 0 is always queried. This option should be

used if a multi-LUN device responds to unoccupied

LUNs or if it is desired to reduce the visibility of a

multi-LUN device to LUN 0 only.

Set this option to No if you have problems with a device

that responds to all LUNs whether they are occupied or

not. Also, if a SCSI device with multiple LUNs exists on

your system but you do not want all of those LUNs to be

available to the system, then set this option to No. By

doing so, you will limit the scan to LUN 0.

Disconnect

Configuration

[On / Off]

Indicates whether to allow a device to disconnect during

SCSI operations. Some (usually newer) devices run

faster with disconnect enabled, while some (usually

older) devices run faster with disconnect disabled.

SCSI Timeout

Executable

[0–9999]

Indicates the maximum allowable time for completion of

a SCSI operation in seconds. Since time-outs provide a

safeguard that allow the system to recover should an

operation fail, it is recommended that a value greater

than zero be used. A value of zero allows unlimited time

for an operation to complete and could result in the

system hanging (waiting forever) should an operation

fail.

Appendix A

Technical Specifications

This appendix discusses the physical environment associated with the

SYM22902 host adapter. It includes a mechanical drawing of this board,

which is shown in Figure A.1. It also includes these topics:

•

Section A.1, “Physical Environment,” page A-1

Section A.2, “Operational Environment,” page A-3

Section A.3, “Subsystem ID and Subsystem Vendor ID,” page A-9

A.1 Physical Environment

This section discusses the physical, electrical, thermal, and safety

characteristics of the SYM22902 host adapter board. Additionally, this

board is compliant with electromagnetic standards set by the FCC.

A.1.1 Physical Characteristics

The dimensions of the SYM22902 host adapter board are approximately

6.60 x 2.53 inches. PCI connection is made through edge connector J1.

The component height on the top and bottom of the SYM22902 follows

the PCI Local Bus Specification, Revision 2.2 standard.

Internal 16-bit SCSI connection is made through the 68-pin high density

connector J4 for Channel B. External SCSI connection is made through

the 68-pin VHDCI connector J2 for Channel A.

The J2 connector extends through the Low Profile PCI (LPPCI) or

ISA/EISA bracket, which is attached to the face of the connector outside

of the cabinet where the SYM22902 is installed. The J3 connector is

used to connect the Busy LED. It is a 4-pin one row right-angle header

for both Channel A and Channel B.

the following parameters:

•

Temperature range: 0 °C to 55 °C (dry bulb)

Relative humidity range: 5% to 90% noncondensing

Maximum dew point temperature: 32 °C

The board is designed for a storage and transit environment, which is

defined by the following parameters:

•

Temperature range: − 45 °C to + 105 °C (dry bulb)

Relative humidity range: 5% to 90% noncondensing

A.1.4 Electromagnetic Compliance

This board is tested to and meets class B regulatory requirements for

United States, Canadian, European, Japanese, and Australian markets

and carries the appropriate markings (FCC, CE, VCCI, C-Tick) indicating

such compliance.

A.1.5 Safety Characteristics

The bare board meets or exceeds the requirements of UL flammability

rating 94 V0. The bare board is also marked with the supplier’s name or

trademark, type, and UL flammability rating. Since this board is installed

in a PCI bus slot, all voltages are below the SELV 42.4 V limit.

A.2 Operational Environment

The SYM22902 is designed for use in PCI computer systems with either

a standard ISA/EISA or LPPCI bracket type. The SDMS software

operates the board, but the design of the board does not prevent the use

of other software. An on-board Flash memory device is provided to allow

BIOS code and open boot code support through PCI and a serial

EEPROM for each channel.

Operational Environment

A-3

A.2.1 The PCI Interface

The PCI interface operates as a 32-bit or 64-bit DMA bus master. The

connection is made through edge connector J1, which provides

connections on both the front and back of the board. The signal

definitions and pin numbers conform to the PCI Local Bus Specification,

Revision 2.2 standard. The signal assignments appear in Table A.2,

Table A.3, and Table A.4.

Note:

The SYM22902 board uses 3.3 V pins to run the

SYM53C896 chip and some other parts. The 3.3 V is

required for the board to work through the host system.
