1.3 Interface Descriptions

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

Interface, and the SCSI Activity LED Interface. It also provides

information about cabling.

1.3.1 The PCI Interface

PCI is a high-speed standard local bus for interfacing a number of I/O

components to a PC processor and memory subsystem. The PCI

1-4 Using the LSI21003

functionality for the LSI21003 is contained within the LSI53C1010-33.

The chip connects directly to the PCI bus and generates timing protocol

in compliance with the PCI specification.

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

is made through edge connector J1 (see Figure 2.1). The signal

definitions and pin numbers conform to the PCI Local Bus Specification

Revision 2.2 standard. The LSI21003 conforms to the PCI universal

signaling environment for a 5 V or 3.3 V PCI bus.

1.3.2 The SCSI Interface

The SCSI functionality for the host adapter is also contained within the

LSI53C1010-33. The chip connects directly to the two SCSI buses for SE

or LVD SCSI applications and generates timing and protocol in

compliance with SCSI standards. One SCSI interface operates at a burst

transferrateofupto40Mbytes/sforwideUltraSCSItransfers,andthe

other up to 160 Mbytes/s for wide Ultra160 SCSI transfers.

Channel A is SE only with active autosensing termination. The

Channel A interface is made through connectors J2, J3, and J4.

Connector J2 is a 68-pin high density right-angle receptacle for internal

SCSI connections. Connector J3 is a 50-pin high density right-angle

receptacle that protrudes through the ISA/EISA bracket. Connector J4 is

a 50-pin narrow (ribbon) internal connector.

Channel B may be either SE or LVD with active termination always

enabled. The Channel B interface is made through connector J5. J5 is a

68-pin high density right-angle connector for internal SCSI connections.

See Figure 2.1 on page 2-5 for the location of these connectors.

The LSI21003 supplies SCSI bus TERMPWR through a blocking diode

and self-resetting 1.5 A short circuit protection device.

A 40 MHz oscillator on the host adapter provides the clock frequency to

the LSI53C1010-33 that is necessary to support SCSI transfers.

Interface Descriptions 1-5

1.3.3 SCSI Activity LED Interface

The SCSI activity LED interface is a four-wire arrangement that allows

connection of an LED harness to the board. The connector on the host

adapter is J6 for both channels. See Table 3.8 on page 3-12 for the signal

name and pin numbers on this interface.

1.3.4 Cabling

The cable provided in the kit is matched for a Fast/Ultra/Ultra2/Ultra160

SE or LVD operation. This cable also has built-in multimode (SE/LVD)

termination since most Ultra160 hard disk drives are not made with

on-board LVD termination.

Table 1.1 lists standard cable specifications.

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.

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

•Section 2.3, “Setting SCSI IDs,” page 2-22

•Section 2.4, “Setting Interrupts (Exceptional Cases),” page 2-24

•Section 2.5, “Completing the Installation,” page 2-25

2.1 Quick Installation Procedure

This section provides quick setup instructions for the experienced

computer user with prior host adapter installation and SCSI bus setup

experience. If you prefer more detailed guidance for installing the

LSI21003, please follow the instructions in Section 2.2, “Detailed

Installation Procedure.”

For safe and proper installation, check the user’s manual that was

supplied with your computer and perform the following steps.

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

Note: The use of a static ground strap is recommended.

Step 2. Remove the LSI21003 from the packing and check that it is not

damaged.

Step 3. Switch off and unplug the system.

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

slots.

Step 5. Locate the slots for the PCI plug-in board installation.

2-2 Installing the LSI21003

A 32-bit slot should be used. The LSI21003 will work in a

64-bit slot, but only 32 bits are used. The host adapter requires

a PCI slot that allows bus master operation. See Figure 2.2 on

page 2-6.

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 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. See the example in

Figure 2.2.

Note: You may notice that the components on the PCI Host

Adapter face the opposite way from those on other non-PCI

plug-in boards you have in your system. This is correct, and

the board is keyed to go in only one way.

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

internal and external SCSI bus connections (see Figure 2.2).

Step 9. If you are connecting any internal SCSI devices, plug the end

of an appropriate internal SCSI ribbon cable into the connector

that provides the performance/features your system needs (see

Figure 2.1 on page 2-5).

Make certain you match pin 1 on both connectors. Chain your

internal devices on this cable.

Step 10. Connect the LED cable to J6 if desired.

This is designed to drive the front panel LED found on most PC

cabinets to indicate activity on the SCSI bus. See Table 3.8 for

the signal name and pin numbers for the LED interface.

Step 11. Make all external SCSI bus connections.

Step 12. Terminate the SCSI bus.

Step 13. Set SCSI IDs as required.

You must not have duplicate SCSI IDs.

Step 14. Replace the cabinet cover.

Step 15. Refer to the PCI Storage Device Management System SDMS

4.0 User’s Guide (or the guide for the software that you will use)

to load the driver software for your particular operating system.

Detailed Installation Procedure 2-3

2.2 Detailed Installation Procedure

This section provides step-by-step instructions for installing your

LSI21003 and connecting it to your SCSI peripherals. If you are

experienced in these tasks, you may prefer to use Section 2.1, “Quick

Installation Procedure.” If you are not confident that you can perform the

tasks as described here, LSI Logic suggests getting assistance.

2.2.1 Before You Start

Before you start, look through the task list below to get an overall idea

of the steps to perform.

•Open your PC cabinet and select an open PCI slot

•Insert the host adapter

•Connect your internal and external SCSI peripherals

•Terminate the SCSI bus

•Set the peripheral SCSI IDs

•Make any configuration changes

•Replace your PC cabinet cover

•Install the software

The SCSI host adapter acts on your computer’s behalf as the host to

your suite of SCSI peripherals. Each chain of SCSI peripheral devices

and their host adapter work together, and they are referred to as a SCSI

bus.

Each SCSI host adapter that you install can act as host for up to

15 peripheral devices (depending on the SCSI bus speed), not including

the adapter itself.

2-4 Installing the LSI21003

2.2.2 Inserting the Host Adapter

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

your computer and perform the following steps:

Step 1. Ground yourself before removing the host adapter board from

its package.

Note: Static charges on your body can damage 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 2. Remove the LSI21003 from its packing and verify that it is not

damaged.

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

Step 3. Switch off the computer and unplug power cords for all

components in your system.

Step 4. Remove the cover from your computer per the instructions in

the user’s manual for your system to access the PCI slots.

Make sure you are adequately grounded.

Step 5. Locate the slots for PCI plug-in board installation.

A 32-bit slot should be used. The LSI21003 will work in a

64-bit slot, but only 32 bits are used. The host adapter 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.

Step 7. Carefully insert edge connector J1 (see Figure 2.1) of the host

adapter into the PCI slot.

Make sure the edge connector is properly aligned before

pressing the board into place as shown in Figure 2.2.The

bracket around connector J3 should fit where you removed the

blank panel.

Note: You may notice that the components on a PCI host adapter

face the opposite way from non-PCI adapter boards you

Detailed Installation Procedure 2-5

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

is keyed and can only be inserted one way.

Step 8. Secure the board with the bracket screw (see Figure 2.2)before

making the SCSI bus connections.

Detailed Installation Procedure 2-7

For convenience, Channel A also has a 50-pin narrow (ribbon) connector.

Some internal cables come with an SE/LVD terminator on one end. This

end should be furthest from the host adapter.

All external SCSI bus connections to the LSI21003 are made with a

shielded, 50-pin high density cable (see Figure 2.3). The connectors on

this cable are always keyed to ensure a proper pin-1 connection.

2.2.3.1 Making Internal SCSI Bus Connections

This section provides step-by-step instructions about making internal

SCSI bus connections. If you have no internal devices to connect,

proceed to Step 4.

Step 1. Plug one end of a SCSI ribbon cable into an appropriate

connector, J2, J4, or J5. The example in Figure 2.4 shows a

wide cable.

Channel A (J2 and J4) supports SE mode. Channel B (J5)

supports SE and LVD modes.

Figure 2.4 Internal SCSI Ribbon Cable to Host Adapter

Detailed Installation Procedure 2-9

Step 2. Plug the other end of the cable into the connector on the

internal SCSI device.

An example of this connection appears in Figure 2.5.

Figure 2.5 Internal SCSI Ribbon Cable to Internal SCSI Device

Connection

If this is the only internal device on the bus, proceed to Step 4.

If you have more than one internal device to connect, use an

internal SCSI ribbon cable with the required number of

connectors attached along its length and proceed to Step 3.

2-10 Installing the LSI21003

Step 3. Plug the cable into each additional device as illustrated in

Figure 2.6.

Figure 2.6 Connecting Additional Internal SCSI Devices

Detailed Installation Procedure 2-11

An example of multiple internal SCSI devices chained together is

shown in Figure 2.7.

Figure 2.7 Multiple Internal SCSI Devices Chained Together

2-12 Installing the LSI21003

Most PC cabinets are designed with a front panel LED. If you wish to

enable this feature, follow Step 4.

Step 4. Connect the LED cable to connector J6 on the host adapter, as

shown in Figure 2.8.

When properly connected, the front panel LED lights when

there is activity on the SCSI bus.

Connector J6 is not keyed. The orientation of the LED cable

should not matter as long as all four pins are connected. If the

LED does not light during SCSI bus activity from this host

adapter, you may have to rotate the LED cable connector 180°

on J6. If your connector has only two wires, refer to Table 3.8

on page 3-12 for connector pinout information.

2.2.3.2 Making External SCSI Bus Connections

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

bus connections. If you have only internal devices, proceed to Section

2.2.4, “SCSI Bus Termination,” page 2-15. To connect external SCSI

devices to the LSI21003:

Step 1. Plug the 50-pin HD connector on one end of a shielded external

SCSI cable into the host adapter connector J3 (see Figure 2.1).

This connector is in the bracket attached to the back panel of

your computer. Figure 2.9 shows how this connection is made.

Figure 2.9 External Cable to Host Adapter

2-14 Installing the LSI21003

Step 2. Plug the 50-pin high density connector on the other end of the

shielded external SCSI cable into the SCSI connector on the

external SCSI device. An example of this connection is shown

in Figure 2.10.

Figure 2.10 External Cable to External SCSI Device

If this is the only external SCSI device on your system, proceed

to Section 2.2.4, “SCSI Bus Termination,” page 2-15, for

termination instructions. If you have multiple external devices,

proceed to page 2-15.

Detailed Installation Procedure 2-15

Step 3. Chain multiple devices together with shielded external SCSI

cables.

An example of these chained connections is shown in

Figure 2.11.

Figure 2.11 Multiple External SCSI Devices Chained Together

2.2.4 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. Remember that your LSI21003 is also on the SCSI

2-16 Installing the LSI21003

bus and its termination is automatically enabled when it is connected to

the end of the bus.

Important: To utilize Ultra160 SCSI performance, you must only have

LVD devices on the bus. Do not mix any SE devices with

LVD devices or the entire bus will drop to SE, limiting bus

performance to Ultra SCSI levels.

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

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

terminator setting of each device and how to change it.

Caution: The autoenable/disable sensing feature on your LSI21003

may enable termination erroneously if it is directly cabled to

another SCSI device or host adapter using the same

sensing method. The LSI21003 senses SCSI devices by

detecting the ground signal on conductor 22 of a

50-conductor internal cable, conductor 36 of a

50-conductor external cable, or conductor 50 of a

68-conductor cable.

The LSI21003 automatically controls SCSI bus termination for four

different bus configurations. The four bus configurations are:

•Connections for high density internal SCSI connections

•Connections to high and low density internal connectors

•Connections for external SCSI connection

•Connections to both internal and external SCSI connectors

These terminations are discussed below. Please note that only SE

termination control is allowed on Channel A.

2.2.4.1 High Density Internal SCSI Connections

If only internal SCSI device connections on the host adapter have been

made, then terminate the last internal device on the SCSI bus. You must

disable the termination on all other devices. Termination on the LSI21003

is automatically enabled for Channel A. The termination for Channel B is

enabled all the time.

Detailed Installation Procedure 2-17

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

SCSI bus configuration.

2.2.4.2 Internal SCSI Connections for Both Internal Connectors

If internal SCSI device connections to both internal connectors (J2 and

J4) on your host adapter have been made, then terminate the internal

devices on each end of the SCSI bus. You must disable the termination

on all other devices. Termination on Channel A of your host adapter is

automatically disabled in this case. Remember, you must not use the

external connector J3 if you use both internal connectors.

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

SCSI bus configuration.

2.2.4.3 External SCSI Connections

If only external SCSI device connections to the host adapter have been

made, then terminate the last external device on the SCSI bus. You must

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

adapter is automatically enabled for Channel A.

2.3 Setting SCSI IDs

Set each SCSI device and the host adapter to a separate SCSI ID,

0 through 15. SCSI ID 7 is the preset host adapter setting, giving it the

highest priority on the 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 2 “SCSI BIOS” of the PCI Storage

Device Management System SDMS 4.0 User’s Guide explains how to set

your host adapter ID using the SCSI BIOS Configuration Utility.

Note: Devices on a narrow (8-bit) bus only respond to SCSI IDs

0–7. Also, they will not be able to respond to the host

adapter if the host adapter ID is set higher than 7.

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 computer’s users manual to determine the ID of

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

on a SCSI bus.

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

any duplications.

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

IDs for future reference.

Table 2.1 is provided to keep this record.

2.4 Setting Interrupts (Exceptional Cases)

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

LSI21003, since performance is usually increased by having two

separate interrupts.

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

INTA/INTB/ jumper is provided to change the interrupt routing. This

capability requires enabling the INTA/INTB/ to act as a jumper for special

configuration purposes. This feature is not packaged with the standard

LSI21003, as the default interrupt routing is sufficient for most systems.

In the exceptional case, where a user would require jumper settings,

Table 2.2, “Setting Interrupts,” explains these settings:

Contact Technical Support for further information concerning jumper

settings for this board.

open boot code support through the PCI bus and a serial EEPROM for

each channel.

3.2.1 The PCI Interface

The PCI interface operates as a 32-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 Tables 3.2 and 3.3.

Note: The +3.3 V pins are tied together and decoupled with high

frequency bypass capacitors to ground. No current from

these 3.3 V pins is used on the board. The PCI portion of

the LSI53C1010 is powered by 3.3 volts from the

on-board regulator.

3.2.2 The SCSI Interface

The SCSI interface conforms to ANSI X3T10.11/1142.

The SCSI interface operates as two 16-bit, SE or LVD channels, and

supports Fast, Ultra, Ultra2, and Ultra160 SCSI protocols. The interface

is made through connectors J2, J3, and J4 for Channel A and J5 for

Channel B.

J2 is a 68-pin high density right-angle connector for internal SCSI

connections to Channel A. J3 is a 50-pin high density right-angle

connector that protrudes through the ISA/EISA bracket for external

connections to Channel A. Also on Channel A is connector J4, which is

a 50-pin narrow (ribbon) connector for internal connections. Channel A

has autosensing, active SE SCSI termination.

J5 is a 68-pin high density latching right-angle connector for internal

SCSI connections to Channel B. Channel B has active, SE or LVD SCSI

termination that is always enabled.

SCSI TERMPWR is supplied by the board.

Tables 3.4,3.5,3.6,and3.7 document the signal assignments for J2, J3,

J4 and J5 respectively.

Glossary of Terms and Abbreviations A-5

Parity Checking A way to verify the accuracy of data transmitted over the SCSI bus. The

parity bit in the transfer is used to make the sum of all the 1 bits either

odd or even (for odd or even parity). If the sum is not correct, the

information may be retransmitted or an error message may appear.

Passive

Termination The electrical connection required at each end of the SCSI bus,

composed of a set of resistors. It improves the integrity of bus signals.

PCI Peripheral Component Interconnect. A local bus specification that allows

connection of peripherals directly to computer memory. It bypasses the

slower ISA and EISA buses.

Peripheral

Devices A piece of hardware (such as a video monitor, disk drive, printer, or

CD-ROM) used with a computer and under the computer’s control. SCSI

peripherals are controlled through a SCSI host adapter.

Pin-1

Orientation The alignment of pin 1 on a SCSI cable connector and the pin-1 position

on the SCSI connector into which it is inserted. External SCSI cables are

always keyed to insure proper alignment, but internal SCSI ribbon cables

sometimes are not keyed.

PIO Programmed Input/Output. A way the CPU can transfer data to and from

memory using the computer’s I/O ports. PIO is usually faster than DMA,

but requires CPU time.

Port Address Also Port Number. The address through which commands are sent to a

host adapter board. This address is assigned by the PCI bus.

Port Number See Port Address.

Queue Tags A way to keep track of multiple commands that allow for increased

throughput on the SCSI bus.

RAM Random Access Memory. The computer’s primary working memory in

which program instructions and data are stored and are accessible to the

CPU. Information can be written to and read from RAM. The contents of

RAM are lost when the computer is turned off.

RISC Core LSI Logic SCSI chips contain a RISC (Reduced Instruction Set

Computer) processor, programmed through microcode SCRIPTS.

ROM Read Only Memory. Memory from which information can be read but not

changed. The contents of ROM are not erased when the computer is

turned off.

SCAM SCSI Configured AutoMatically. A method to automatically allocate SCSI

IDs using software when SCAM compliant SCSI devices are attached.

SCSI Small Computer System Interface. A specification for a high-performance

peripheral bus and command set. The original standard is referred to as

SCSI-1.

SCSI-2 The SCSI specification which adds features to the original SCSI

standard.

SCSI-3 The current SCSI specification which adds features to the SCSI-2

standard.

SCSI Bus A host adapter and one or more SCSI peripherals connected by cables

in a linear chain configuration. The host adapter may exist anywhere on

the chain, allowing connection of both internal and external SCSI

devices. A system may have more than one SCSI bus by using multiple

host adapters.

SCSI Device Any device that conforms to the SCSI standard and is attached to the

SCSI bus by a SCSI cable. This includes SCSI host adapters and SCSI

peripherals.

SCSI ID A way to uniquely identify each SCSI device on the SCSI bus. Each SCSI

bus has eight available SCSI IDs numbered 0 through 7 (or 0 through 15

for Wide SCSI). The host adapter usually gets the highest ID, (7 or 15)

giving it priority to control the bus.

SCSI SCRIPTS A SCSI programming language that works with the SCRIPTS processor

that is embedded on the LSI53C1010-33 device. These SCRIPTS reside

in the host computer system memory.

SCRIPTS

Processor The SCRIPTS processor allows users to fine tune SCSI operations with

regard to unique vendor commands or new SCSI specifications. The

SCRIPTS processor fetches SCRIPTS instructions from system memory

to control operation of the LSI53C8XX device.

SDMS Storage Device Management System. An LSI Logic software product that

manages SCSI system I/O.

Single-Ended

(SE) SCSI A hardware specification for connecting SCSI devices. It references each

SCSI signal to a common ground. This is the most common method (as

opposed to differential SCSI which uses a separate ground for each

signal).

Glossary of Terms and Abbreviations A-7

STA SCSI Trade Association. A group of companies that cooperate to

promote SCSI parallel interface technology as a viable mainstream I/O

interconnect for commercial computing.

Synchronous

Data Transfer One of the ways data is transferred over the SCSI bus. Transfers are

clocked with fixed frequency pulses. This is faster than asynchronous

data transfer. Synchronous data transfers are negotiated between the

SCSI host adapter and each SCSI device.

System BIOS Controls the low-level POST (power-on self-test), and basic operation of

the CPU and computer system.

Ultra SCSI A standard for SCSI data transfers. It allows a transfer rate of up to

20 Mbytes/s over an 8-bit SCSI bus and up to 40 Mbytes/s over a 16-bit

SCSI bus. SCSI Trade Association (STA) supports using the term “Ultra

SCSI”overtheolderterm“Fast-20”.

Ultra2 SCSI A standard for SCSI data transfers. It allows a transfer rate of up to

40 Mbytes/s over an 8-bit SCSI bus, and up to 80 Mbytes/s over a

16-bit SCSI bus. SCSI Trade Association (STA) supports using the term

“Ultra2 SCSI” over the term “Fast-40”.

Ultra160 SCSI A standard for SCSI data transfers. It allows a transfer rate of up to

160 Mbytes/s over a 16-bit SCSI bus.

VCCI Voluntary Control Council for Interference.

VDE Verband Deucher Elektroniker (Association of German Electrical

Engineers).

Virtual Memory Space on a hard disk that can be used as if it were RAM.

Wide SCSI A SCSI-2 feature allowing 16-bit or 32-bit transfers on the SCSI bus. This

dramatically increases the transfer rate over the standard 8-bit SCSI bus.

Wide Ultra SCSI The SCSI Trade Association (STA) term for SCSI bus width 16-bits, SCSI

bus speed maximum data rate 40 Mbytes/s.

Wide Ultra2

SCSI The SCSI Trade Association (STA) term for SCSI bus width 16-bits, SCSI

bus speed maximum data rate 80 Mbytes/s.

Wide Ultra160

SCSI The SCSI Trade Association (STA) term for SCSI bus width 16-bits, SCSI

bus speed maximum data rate 160 Mbytes/s.
