Chapter 1
Using the
LSI20860

This chapter contains instructions and illustrations to help you install a
LSI20860 PCI to Ultra SCSI host adapter board into a PCI computer
system. It includes these topics:

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

• Section 1.2, “Installing the LSI20860,” page 1-5

• Section 1.3, “Connecting SCSI Devices,” page 1-7

• Section 1.4, “Troubleshooting,” page 1-12

1.1 General Description

The LSI20860 provides a low-cost SCSI solution for attaching SCSI
devices (disk drives, scanners, CD-ROM drivers, tape drives, removable
media drives, etc.) to PCI computer systems with an ISA/EISA bracket
type. The LSI20860 uses the LSI53C860 PCI to Ultra SCSI I/O
Processor chip, an 80 MHz oscillator, and transfers SCSI data up to
20 Mbytes/s.

1.1.1 Features

This section provides a high leveloverview of the PCI Interface, the SCSI
Interface, and Board Characteristics for the LSI20860.

1.1.1.1 PCI Interface

• Full 32-bit DMA bus master

• Zero wait-state bus master data bursts

• Supports 5 V

LSI20860 PCI to Ultra SCSI Host Adapter 1-1

1.1.1.2 SCSI Interface

• Supports 8-bit Single-Ended (SE) signaling only

• Automatically enables SE termination

• Supports SCSI termination power (TERMPWR) source

• External: 50-pin high density; Internal: 50-pin low density connectors

• Provides Ultra SCSI synchronous transfer capability up to

20 Mbytes/s

1.1.1.3 Board Requirements

• PCI board dimensions: 2.5 x 4.75 inches

• PCI 5 V signaling environment

• ISA/EISA bracket type

The Storage Device Management System (SDMS™) software includes

1.1.2 Physical Environment

This section discusses the physical, electrical, thermal, and safety
characteristics of the LSI20860. Additionally, this board is compliant with
Class B electromagnetic standards set by the FCC.

1.1.2.1 Physical Characteristics

The dimensions of the LSI20860 are 2.5 x 4.75 inches. PCI connection
is made through edge connector J1.

Internal SCSI connection is made through the 50-pin low density
connector J2. External SCSI connection is made through the 50-pin high
density connector J3. The J3 connector extends outside the cabinet
through a bracket attached to the board and the face of the connector.
The bracket is a standard ISA type with a cutout to accommodate
connector J3.
