Chapter 1 Describing the LSI8751D

This chapter describes how the LSI8751D PCI to SCSI Host Adapter interfaces to PCI computer systems and includes these topics:

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

• Section 1.2, “Features,” page 1-2

1.1 General Description

The LSI8751D provides a SCSI-3, Ultra SCSI interface to PCI computer systems. Installing this adapter in your PCI system allows you to connect SCSI devices over a SCSI bus.

The LSI8751D is a 16-bit, High Voltage Differential (HVD), Ultra SCSI solution for your computer, using only one PCI slot. This board can support both legacy Fast SCSI devices and the newest Ultra SCSI devices. It is also backward compatible with the existing LSI8251D host adapter.

The Storage Device Management System (SDMS™) software operates the board, but the design of the board does not prevent other software from being written and used with it.

This guide and the PCI Storage Device Management System SDMS 4.0 User’s Guide contain product information and installation instructions. This information helps you gain the full beneﬁts of the LSI8751D for your computer system.

LSI8751D PCI to SCSI Host Adapter 1-1

1.2 Features

This section provides an overview of the PCI interface, the SCSI interface, and board characteristics for the LSI8751D.

BIOS support for this host adapter is incorporated on the board in an 8 x 64 Kbytes Flash BIOS.

1.2.1 PCI Interface

PCI is a high-speed standard local bus for interfacing a number of I/O components to the processor and memory subsystems in a high-end PC. The PCI functionality for the LSI8751D is contained within the LSI53C875J PCI to SCSI I/O Processor chip. The LSI53C875J connects directly to the PCI bus and generates timing protocol that complies with the PCI speciﬁcation.

The PCI interface on the LSI8751D supports these features:

• Full 32-bit DMA bus master

• Zero wait-state bus master data bursts

• Universal 5 V or 3.3 V PCI bus voltage

• PCI Local Bus Speciﬁcation, Revision 2.1 compliance

1.2.2 SCSI Interface

The SCSI functionality for the LSI8751D is contained within the LSI53875 controller chip. The LSI53C875 connects directly to the SCSI bus and generates timing and protocol in compliance with the SCSI standard.

The SCSI interface on the LSI8751D operates as a 16-bit, synchronous or asynchronous, HVD bus, and supports Ultra SCSI protocols and 16bit arbitration. The LSI8751D provides HVD SCSI termination as a pluggable terminator. This terminator plugs into either the internal or external 68-pin high density connector (J2 or J3).

The SCSI interface for this board supports these features:

• 16-bit HVD

• External plug-in termination supplied with board

1-2 Describing the LSI8751D

• 68-pin high density external dual connector

• 68-pin high density internal dual connector

• Fast and Ultra SCSI data transfer capability

• SCSI termination power (TERMPWR) source with autoresetting

circuit breaker

• Flash EEPROM for BIOS storage

• Serial NonVolatile Random Access Memory (NVRAM) for user

conﬁguration utility.

• SCSI activity LED connector

1.2.3 Board Characteristics

The board characteristics are

• PCI host adapter dimensions –

5.00 x 3.25 inches (127 X82.552 mm)

• Universal 32-bit card edge connector

1.2.4 Ultra SCSI

The LSI8751D has full support for Ultra SCSI and simultaneously supports Fast SCSI. Ultra SCSI is an extension of the SCSI-3 family of standards that expands the bandwidth of the SCSI bus, allowing faster synchronous data transfers. Special SCSI cables are speciﬁed for operation with Ultra SCSI devices, and you must consider the total number of devices and the length of your SCSI bus when setting up your system. See Section 1.2.3, “Connecting the SCSI Peripherals,” page 1-5 for a more detailed explanation of SCSI bus connections.

Chapter 2 Installing the LSI8751D

This chapter provides instructions on how to install the LSI8751D and includes these topics:

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

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

• Section 2.3, “Completing the Installation,” page 2-21

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 LSI8751D, please follow the instructions in 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 this host adapter board, then

remove the cabinet cover on your computer to access the PCI slots.

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

Step 2. Remove the LSI8751D from the packing and check that it is not

damaged. Step 3. Turn off and unplug your system. Step 4. Open your PC cabinet. Step 5. Locate the slots for installing a PCI plug-in board. Step 6. Insert the LSI8751D board into the selected PCI slot.

LSI8751D PCI to SCSI Host Adapter 2-1

Step 7. Connect the internal and external SCSI peripherals.

Optional: Connect the LED cable on your SCSI host adapter. Step 8. Terminate the SCSI bus.

The SCSI bus requires proper termination and no duplicate

SCSI IDs. Step 9. Set the peripheral SCSI IDs. Step 10. Make any conﬁguration changes. Step 11. Replace your PC cabinet cover. Step 12. Plug in your computer and peripherals. Step 13. Turn on the peripherals, and then your computer.

The host adapter installation is complete. Refer to the 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 particular operating system. Additionally, this guide contains documentation about the SCSI BIOS Conﬁguration Utility, which provides a means to change system conﬁguration.

2.2 Detailed Installation Procedure

This section provides step-by-step instructions for installing the LSI8751D and connecting it to your SCSI peripherals. If you are experienced in these tasks, you may prefer to use the instructions in the preceding Section 2.1, “Quick Installation Procedure.”

2.2.1 Before You Start

Before starting, read through the steps deﬁned within the detailed installation procedure. If you are not conﬁdent that you can perform the tasks as described in this section, LSI Logic suggests getting assistance.

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 are referred to as a SCSI bus.

Each channel on your SCSI host adapter can act as host for up to 15 peripheral devices, not including the adapter itself.
