1-4 Using the LSI21002
1.3 Interface Descriptions
This section provides a more detailed explanation about the PCI
Interface, the SCSI Interface, the SCSI Activity LED Interface, and Wide
Ultra2 SCSI.
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
functionality for the LSI21002 is contained within the LSI53C896 PCI
Dual Channel SCSI Multifunction Controller. The LSI53C896 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 2.1 standard. The LSI21002 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 LSI21002 is contained within the
LSI53C896 chip. The LSI53C896 connects directly to the two SCSI
buses for SE or LVD SCSI applications and generates timing and
protocol in compliance with the SCSI standard. One SCSI interface
operates at a burst transfer rate of up to 40 Mbytes/s for wide Ultra SCSI
transfers, and the other up to 80 Mbytes/s for wide Ultra2 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 latching right angle receptacle for
internal SCSI connections. Connector J3 is a 50-pin high density right
angle receptacle that protrudes throughout 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 latching right angle connector for internal SCSI
connections.

Interface Descriptions 1-5
See Figure 2.1 for the location of these connectors.
The LSI21002 supplies SCSI bus TERMPWR through a blocking diode
and self-resetting 1.5 A short circuit protection device. An on-board LED
lights up when TERMPWR is shorted and has turned off.
A 40 MHz oscillator is installed on the LSI21002 to provide the clock
frequency to the LSI53C896 that is necessary to support SCSI transfers.
1.3.3 SCSI Activity LED Interface
The LSI21002 LED interface is a four-wire arrangement that allows
connection of an LED harness to the board. The connector on the
LSI21002 is J6 for both channels. See Table A.7 in Appendix A for the
signal name and pin numbers for this LED interface.
1.3.4 Wide Ultra2 SCSI
The LSI21002 has full support for 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 Ultra SCSI interface, while it allows increased cable length and more
devices than Ultra SCSI interfaces.
Special SCSI cables are specified for operation with Wide Ultra and
Ultra2 SCSI devices, and you must consider the total number of devices
and the length of your SCSI bus when setting up your system. The
section on connecting your SCSI peripherals in Chapter 2, "Installing the
LSI21002," provides a more detailed explanation of SCSI bus
connections. See Table 1.1for maximum bus lengths in meters.
When you purchased the LSI21002 kit, the cable provided in the kit is
matched for a 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.

LSI21002 PCI to Dual Channel SCSI Host Adapter 2-1
Chapter 2
Installing the LSI21002
This chapter describes installing the LSI21002 into PCI computer
systems 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, “Setting Interrupts (Exceptional Cases),” page 2-24
•Section 2.4, “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
LSI21002, 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. Before proceeding, ground yourself so that a static discharge
does not damage the board. Remove the LSI21002 from the
packing and check that it is not damaged. An example of this
host adapter board is shown in Figure 2.1.
Step 2. Switch off and unplug the system.
Step 3. 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
electronic components. Handle plug-in boards by the edge;

2-2 Installing the LSI21002
do not touch board components or gold connector contacts.
The use of a static ground strap is recommended.
Step 4. Locate the slots for the PCI plug-in board installation. A 32-bit
slot should be used. The LSI21002 will work in a 64-bit slot, but
only 32 bits are used. The LSI21002 requires a PCI slot that
allows bus master operation. See Figure 2.2.
Step 5. Remove the blank panel on the back of the computer aligned
with the PCI slot that you intend to use. Save the bracket screw.
Step 6. Carefully insert edge connector J1 of the host adapter into the
PCI slot. Make sure the edge connector is properly engaged
before pressing the board into place. See the example shown
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 7. The bracket around connector J3 should fit where the blank
panel was removed. Secure it with the bracket screw before
making the internal and external SCSI bus connections (see
Figure 2.2).
Step 8. If you are connecting any internal SCSI devices, plug a 68-pin
connector on the end of the internal SCSI ribbon cable into
connector J2 or J5, or plug a 50-pin connector into J4 for an
8-bit SCSI (see Figure 2.1).Makecertaintomatchpin1onall
connectors.
Note. It is possible to use both internal connectors if no external
devices are attached to the host adapter. You may use only
two of the three connectors at once.
Step 9. Connect your computer’s LED cable if desired. This LED cable
drives the front panel LED found on most PC cabinets to
indicate activity on the SCSI bus. See Table A.7 in Appendix A
for the signal name and pin numbers for this LED interface.
Step 10. Replace the cabinet cover as described in the user’s manual for
your computer.
Step 11. Make all external SCSI bus connections.

Detailed Installation Procedure 2-3
Remember: The SCSI bus requires proper termination and no duplicate
SCSI IDs.
Step 12. 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.
2.2 Detailed Installation Procedure
This section provides step-by-step instructions for installing your
LSI21002 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

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.

2-4 Installing the LSI21002
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. Before proceeding, ground yourself so that a static discharge
does not damage the board. Remove the LSI21002 from the
packing and check that it is not damaged. An example of this
host adapter board is shown in Figure 2.1.
Step 2. Switch off and unplug power cords for all components in your
system.
Step 3. Remove the cabinet cover on your computer to access the PCI
slots.
Caution: Ground yourself by touching a metal surface before
removing the cabinet cover. 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 4. Locate the slots for the PCI plug-in board installation. A 32-bit
slot should be used. The LSI21002 will work in a 64-bit slot, but
only 32 bits are used. The LSI21002 requires a PCI slot that
allows bus master operation. See Figure 2.2.
Step 5. Remove the blank panel on the back of the computer aligned
with the PCI slot that you intend to use. Save the bracket screw.
Step 6. Carefully insert edge connector J1 (see Figure 2.1) of the host
adapter into the PCI slot. Make sure the edge connector is
properly engaged before pressing the board into place as
shown in Figure 2.2.
Step 7. You may notice that the components on the PCI host adapter
face the opposite way from those on other non-PCI adapter
boards you have in your system. This is correct, and the board
is keyed to go in only one way.
