Chapter 1 Describing the LSI20160 This chapter describes the LSI20160 Single Channel Ultra160 SCSI to PCI Host Adapter interface to PCI computer systems and includes these topics: • Section 1.1, “General Description,” page 1-1 • Section 1.2, “Features,” page 1-2 • Section 1.3, “Ultra160 SCSI Benefits,” page 1-4 • Section 1.4, “SureLINK™ Ultra160 SCSI Domain Validation Benefits,” page 1-5 • Section 1.5, “LVDlink™ Technology Benefits,” page 1-5 • Section 1.
The LSI53C1000 contains a SCSI SCRIPTS™ processor that permits both DMA and SCSI commands to be fetched from host memory or internal SCRIPTS RAM. Algorithms written in SCSI SCRIPTS control the actions of the SCSI and DMA cores. The SCRIPTS processor executes complex SCSI bus sequences independently of the host CPU. In addition to this guide there is another reference that you will find useful. The LSI Logic PCI Storage Device Management System SDMS 4.
1.2.2 SCSI Interface The SCSI interface is made through connectors J2 and J4. Figure 2.1 shows the location of these connectors.
1.2.3 Board Characteristics The board characteristics are • PCI board dimensions Approximately 4.721 x 2.536 inches • Universal 32-bit PCI card edge connector • Standard bracket available 1.2.4 SCSI Activity LED Interface The J3 connector is a four-wire arrangement on the LSI20160 that represents the SCSI activity LED interface. Table 3.5 on page 3-8 lists the signal name and pin numbers for this LED interface. 1.
1.3.2 Cyclic Redundancy Check (CRC) Ultra160 SCSI includes CRC which offers higher levels of data reliability by ensuring complete integrity of transferred data. CRC is a 32-bit scheme, referred to as CRC-32. CRC is guaranteed to detect all single bit errors, any two bits in error, or any combination of errors within a single 32-bit range. 1.3.3 Asynchronous Information Protection (AIP) The LSI53C1000 also supports AIP, which protects all nondata phases, including command, status, and messages.
Important: All bus devices must be LVD or SE. If a High Voltage Differential (HVD) device is detected, the board puts the SCSI bus in the high impedance state and shuts down. 1.6 TolerANT® Technology Benefits The LSI20160 features TolerANT technology, which includes active negation on the SCSI drivers and input signal filtering on the SCSI receivers.
Chapter 2 Installing the LSI20160 This chapter provides instructions on how to install the LSI20160 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 2-20 2.1 Quick Installation Procedure This section provides an overview of the installation procedure.
Step 8. Connect the LED cable to J3 on your SCSI host adapter, if you wish to connect the LED to the SCSI LED connector. Step 9. Terminate the SCSI bus. The SCSI bus requires proper termination and no duplicate SCSI IDs. Step 10. Set the peripheral SCSI IDs. Step 11. Make any configuration changes. Step 12. Close your PC cabinet cover. Step 13. Make all external SCSI bus connections. Step 14. Refer to the PCI Storage Device Management System SDMS 4.
2.2.2 Selecting a PCI Slot 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 its package. Step 2. Remove the LSI20160 from its packing and verify it is not damaged. Figure 2.1 shows an example of this host adapter board. Step 3. Switch off and unplug the system. Step 4. Remove the cabinet cover on your computer to access the PCI slots.
2.2.3 Inserting the Host Adapter Perform the following steps to install the LSI20160 in your PC mainboard. Step 1. Remove the blank bracket panel on the back of the computer aligned with the PCI slot you intend to use. Save the bracket screw. Step 2. Carefully insert the 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. The bracket around connector J2 should fit where the blank bracket panel was removed.
Step 3. Secure the bracket with the bracket screw before making the internal and external SCSI bus connections. Figure 2.2 shows an example on how to insert your host adapter.

2.2.4 Connecting SCSI Peripherals All internal SCSI bus connections to the LSI20160 can be made with an unshielded, 68-conductor ribbon cable (see Figure 2.3). One side of this cable is marked with a color to indicate the pin-1 side. The connectors on this cable are keyed to ensure proper pin-1 connection. Some internal cables come with an LVD/SE terminator on one end. This end should be furthest from the host adapter.
2.2.4.1 Making Internal SCSI Bus Connections This section provides step-by-step instructions for making internal SCSI bus connections. If you only have external connections, skip to Section 2.2.4.3, “Making External SCSI Bus Connections.” Step 1. Plug a 68-pin connector on the end of the internal SCSI ribbon cable into connector J4. Figure 2.4 illustrates how to make this connection. Figure 2.
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. Pin 1 must match on all connections. The lead in the cable adjacent to pin 1 is colored. Figure 2.5 illustrates a connection to an internal SCSI device. Figure 2.5 Internal SCSI Ribbon Cable to Internal SCSI Device Connection If you have more than one internal SCSI device, you must have a cable with at least as many connectors as devices.
Step 3. Plug in any additional internal SCSI devices, as required. Refer to the example in Figure 2.6. Figure 2.7 illustrates the connection of multiple internal SCSI devices chained together. Make sure to match pin 1 on all connections. Figure 2.6 Connecting Additional Internal SCSI Devices Detailed Installation Procedure Copyright © 2001 by LSI Logic Corporation. All rights reserved.
Figure 2.7 Multiple Internal SCSI Devices Chained Together 2.2.4.2 Making Activity LED Connection Most PC cabinets are designed with a front panel LED to indicate bus activity. It may already be connected to an existing IDE controller. If you want, you can connect the LED to the SCSI LED connector. Connect the LED cable to J3 on your SCSI host adapter, as shown in Figure 2.8. The Busy LED connector J3 is not keyed. The J3 connector is a 4-pin one row right angle header.
After the correct connection is established, the front panel LED indicates activity on the SCSI bus. Refer to Table 3.5 on page 3-8 for connector pinout information. Figure 2.8 SCSI LED Connector LED Cable LED Connector J3 Detailed Installation Procedure Copyright © 2001 by LSI Logic Corporation. All rights reserved.
2.2.4.3 Making External SCSI Bus Connections This section provides step-by-step instructions for making external SCSI bus connections. Step 1. Plug the 68-pin VHDCI connector on one end of a shielded external high density cable (see Figure 2.3) into the host adapter connector J2. This connector is exposed on the back panel of your computer. Figure 2.9 illustrates where this connection is made. Figure 2.
Step 2. Plug the 68-pin connector on the other end of the shielded external SCSI cable into the SCSI connector on your external SCSI device. Figure 2.10 illustrates a connection to an external SCSI device. Figure 2.10 External Cable to External SCSI Device Detailed Installation Procedure Copyright © 2001 by LSI Logic Corporation. All rights reserved.
Step 3. Chain any additional SCSI devices together with shielded external SCSI cables. Figure 2.11 shows an example of multiple external SCSI devices that are chained together. Figure 2.11 Multiple External SCSI Devices Chained Together 2-14 Installing the LSI20160 Copyright © 2001 by LSI Logic Corporation. All rights reserved.
2.2.5 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. Termination control has two options which allow a different termination mode: • Termination can be disabled by placing a manual shunt over the post.
2.2.5.1 Internal SCSI Terminations If you are making internal SCSI device connections on your host adapter, you must terminate the last internal device on the SCSI bus. You must disable the termination on all other devices. Termination on your host adapter is automatically enabled in this case if there are no external SCSI devices connected through J2. Figure 2.12 shows an example of how termination is determined for this SCSI bus configuration. Figure 2.
2.2.5.2 External SCSI Terminations If you are making external SCSI device connections on your host adapter, you must terminate the last external device on the SCSI bus. Termination on all other devices must be disabled. Termination on your host adapter is automatically enabled in this case if there are no internal devices connected through J4. Figure 2.13 shows an example of how termination is determined for this SCSI bus configuration on your host adapter. Figure 2.
2.2.6 Setting SCSI IDs You must set each SCSI device and the host adapter to a separate SCSI ID. The IDs are 0 through 7 for an 8-bit bus and 0 through 15 for a 16-bit bus. SCSI ID 7 is the preset host adapter setting, giving it the highest priority on the SCSI 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. The PCI Storage Device Management System SDMS 4.

3.2.2 The SCSI Interface The SCSI interface conforms to ANSI X 3T10.11/1142. The SCSI interface operates as 16-bit, synchronous or asynchronous, SE or LVD, and supports Ultra160 SCSI protocols. Arbitration is supported for 8-bit (at lower SCSI speeds) and 16-bit. Active SE or LVD SCSI termination is provided automatically. The LSI20160 supplies the SCSI termination power. Connector J2 makes the external connection, which provides LVD/SE SCSI termination.
3.2.3 The LED Interface The LSI20160 LED interface is a four-wire arrangement that allows you to connect an LED harness to the board. The GPIO0_FETCH line has a maximum output low voltage of 0.4 V and minimum output low current of 16 mA. It is driven low to complete the circuit when a harness with an LED is attached. The J3 connector provides the LED connection on the LSI20160. Table 3.5 lists the signal and pin numbers for the LED interface. Table 3.
3.3 Subsystem ID and Subsystem Vendor ID Table 3.6 provides the Subsystem ID and System Vendor ID for the LSI20160. The serial EEPROM on this board contains the ID numbers. During system initialization, the system loads the ID numbers into the Subsystem Vendor ID and Subsystem ID registers of the LSI20160 SCSI Controller (the LSI53C1000). For more information on the operation of the Subsystem Vendor ID and Subsystem ID registers, refer to the LSI53C1000 PCI to Ultra160 SCSI Controller Technical Manual.
