Chapter 1 Quick Installation Procedures This chapter contains general information about Ultra160 SCSI controllers and host adapters. It provides quick host adapter installation instructions for experienced computer users and instructions for SCSI bus setup. It also provides quick installation instructions for Windows NT or Windows 2000 device drivers. This chapter describes these topics: 1.1 • Section 1.1, “General Description,” page 1-1 • Section 1.
For specific information about the Ultra160 SCSI controllers, refer to the related publications section in the Preface. 1.2 Obtaining Windows NT/Windows 2000 Drivers Before you begin the Ultra160 SCSI host adapter installation, create a Windows NT or Windows 2000 driver diskette by copying the driver files from either the LSI Logic SDMS CD-ROM or from the LSI Logic web site at http://www.lsilogic.com.
1.3 Quick Host Adapter Installation If you are an experienced computer user with prior host adapter installation and SCSI bus setup experience, this section may sufficiently describe the installation procedure for you. If you prefer more detailed instructions and guidance, refer to Section 2.1, “Installing your Ultra160 SCSI Host Adapter,” page 2-1. To install an LSI Logic Ultra160 SCSI to PCI Host Adapter, follow these steps: Step 1.
1.4 Quick Windows NT/Windows 2000 Driver Installation To load the SYM_U3.SYS miniport driver during a new Windows NT or Windows 2000 system installation, you can boot directly from the Microsoft installation CD-ROM. The Windows NT 4.0 and Windows 2000 drivers are not interchangeable, however the instructions are very similar. To install a new Windows NT or Windows 2000 operating system and its appropriate device driver, follow these steps: Step 1.
Chapter 2 Detailed Host Adapter Installation This chapter provides detailed instructions on how to install the LSI Logic Ultra160 SCSI to PCI host adapters and includes these topics: 2.1 • Section 2.1, “Installing your Ultra160 SCSI Host Adapter,” page 2-1 • Section 2.2, “Connecting SCSI Peripherals,” page 2-4 • Section 2.3, “Terminating the SCSI Bus,” page 2-8 • Section 2.
Step 4. Remove the cabinet cover on your computer to access the PCI slots. Step 5. Locate the PCI slots on your computer. Use a 32-bit slot for 32-bit host adapters and a 64-bit slot for 64-bit host adapters. You may insert a 64-bit host adapter into a 32-bit slot if not 64-bit slots are available. Refer to the user’s manual supplied with your computer to confirm the location of the PCI slots. 2.1.

Inserting the Host Adapter Secure the bracket with the bracket screw. 32-Bit slots If you plug a 64-bit card into a 32-bit slot, be careful not to damage the main board. 64-Bit slots 2.2 Connecting SCSI Peripherals This section provides information about making internal and external SCSI connections. 2.2.
Step 1. Plug the 68-pin connector on the SCSI ribbon cable into the internal connector on the host adapter board. Figure 2.3 illustrates how to make this connection. Figure 2.3 Internal SCSI Ribbon Cable to Host Adapter 68-Pin High Density Ribbon Cable (See Figure 3.8 and Figure 3.9 for examples of internal ribbon cables.) 68-Pin Connector Internal Connectors Step 2. Plug the 68-pin connector on the other end of the internal SCSI ribbon cable into the SCSI connector on the internal SCSI device.
Step 3. Plug in any additional internal SCSI devices, as required. Figure 2.4 Multiple Internal SCSI Devices Chained Together Last Device on Chain– Termination Enabled External Connector J5 Connector– Used to connect multiple internal SCSI devices Internal Connectors 2.2.2 Making External SCSI Bus Connections This section provides step-by-step instructions for making external SCSI bus connections. Refer to Section 3.3.
Figure 2.5 shows an example of an external SCSI connection to a single external SCSI device. If you have the correct cable, it matches the external connector. Termination occurs on the last SCSI device. See Section 2.3, “Terminating the SCSI Bus,” for more information about SCSI bus termination. Figure 2.5 External SCSI Connection to an External SCSI Device Terminator External Connector Step 3. Chain any additional SCSI devices together with shielded external SCSI cables. Figure 2.
Figure 2.6 Multiple External SCSI Devices Chained Together Last Device on Chain– Termination Enabled These Devices Do Not End Chain– Termination Disabled Host Adapter External Board Connector– Plugging in automatically enables termination 2.3 Terminating the SCSI Bus 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.
The Ultra160 SCSI host adapters automatically control SCSI bus termination for various bus configurations. In one case, you may disable termination by using BIOS software control to change the BIOS termination from Automatic to Off. In another case where jumpers are provided on the board, you would locate the shunts on the board for autotermination override. Termination can be disabled by placing a manual shunt over the post. When the shunt is off, the terminator is active.
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 user’s manual for your computer to determine the ID of each device and how to change it. No duplication of SCSI IDs is allowed on a SCSI bus. To set your SCSI IDs, follow these steps: Step 1. Determine the SCSI ID of each device on the SCSI bus. Step 2. Make any necessary changes to the SCSI IDs and record the IDs for future reference.
2.4 Completing the Installation Before replacing the cover on your computer, review this installation procedure check list. This can save you effort later. Verify Installation Procedures Done Host adapter connection in PCI bus slot secure (level) Internal SCSI bus connections secure (pin-1 continuity) External SCSI bus connections secure Proper SCSI bus termination established Unique SCSI IDs set and recorded for each device Step 1. Replace the cabinet cover on your computer. Step 2.

Appendix A Glossary of Terms and Abbreviations Active Termination The electrical connection required at each end of the SCSI bus, composed of active voltage regulation and a set of termination resistors. Ultra, Ultra2, and Ultra160 SCSI require active termination. AIP Asynchronous Information Protection (AIP) provides error checking for asynchronous, nondata phases of the SCSI bus. BIOS Basic Input/Output System. Software that provides basic read/write capability. Usually kept as firmware (ROM based).
Domain Validation Domain Validation is a software procedure in which a host queries a device to determine its ability to communicate at the negotiated Ultra160 data rate. Double Transition Clocking In Double Transition (DT) Clocking, data is sampled on both the asserting and deasserting edge of the REQ/ACK signal. DT clocking may only be implemented on an LVD SCSI bus. EEPROM Electronically Erasable Programmable Read Only Memory. A memory chip typically used to store configuration information.
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. RAM Random Access Memory.
Single-Ended 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 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.
