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

Interface Descriptions 1-3

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.

1-4 Using the LSI21003

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.

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 Voltage Differential (HVD) are not defined at greater than

Ultra speeds.

slots.

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

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.

Detailed Installation Procedure 2-3

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

Detailed Installation Procedure 2-11

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

Detailed Installation Procedure 2-13

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.

2-14 Installing the LSI21003

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

Detailed Installation Procedure 2-15

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 LSI21003 automatically controls SCSI bus termination for four

different bus configurations. The four bus configurations are:

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.

• 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

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:

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

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

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.

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:

3.1.1 Physical Characteristics

The dimensions of the LSI21003 are approximately 177.8 x 83.8 mm
(7.0 x 3.3 inches). PCI connection is made through edge connector J1.
The component height on the top and bottom of the LSI21003 follows the
PCI specification.

Internal SCSI connections can be made in two ways:

• 68-pin high density connectors J2 for Channel A or J5 for

Channel B (16-bit).

• 50-pin low density connector J4 for Channel A (8-bit).

External SCSI connection is made to Channel A through the 50-pin high
density connector J3. Connector J3 extends through the ISA/EISA
bracket.

Connector J6 connects the Busy LED. It is a 4-pin, one row, right-angle
header and indicates bus activity for both Channel A and Channel B.

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 L VD 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.

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

4.333 pc

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.

44.25 pc

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.

4.333 pc

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).

Synchronous
Data Transfer

One of the ways data is transferred ov er 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”.
