Installing this adapter in your PCI system allows connection of SCSI devices over a SCSI bus. The LSI20160L provides one Ultra160 SCSI channel. The LSI20160L supports Low Voltage Differential (LVD) and Single-Ended (SE) SCSI. This board supports Fast/Ultra/Ultra2 SCSI devices as well as the newest Ultra160 SCSI devices. The LSI Logic Storage Device Management System (SDMS™) software operates the board. The design of the board does not prevent other SCSI software from being used with it. BIOS support for this host adapter is incorporated on the board in a 128 Kbytes Flash device. The onboard controller for the LSI20160L is the LSI53C1000 PCI to Ultra160 SCSI Controller. LSI20160L PCI to Single Channel Ultra160 SCSI Low Profile Host Adapter 1-1 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 4.0 User’s Guide contains product information and installation instructions. 1.2 Features This section provides an overview of the PCI Interface, the SCSI Interface, and Board Characteristics for the LSI20160L. 1.2.1 PCI Interface The PCI interface operates as a 32-bit DMA bus master, where the connection is made through the J1 edge connector. The PCI interface includes these features: 1-2 • Complies with PCI Local Bus Specification, Revision 2.2 and LPPCI Specification • Complies with PC99 • Complies with PCI Bus Power Management Specification, Revision 1.1 • Supports 32-bit 33 MHz word data bursts with variable burst lengths • Bursts 4/8, 8/16, 16/32, or 32/64 Qword/Dword transfers across the PCI bus • Bursts up to 264 Mbytes/s (@ 33 MHz) with zero wait-state bus master data • Supports the PCI Cache Line Size (CLS) register • Prefetches up to 8 Dwords of SCRIPTS instructions • Supports PCI Write and Invalidate, Read Line, and Read Multiple commands • Supports universal 3.3 V and 5 V PCI bus signaling environment Describing the LSI20160L 1.2.2 SCSI Interface The SCSI interface is made through connectors J2 and J4. Figure 2.1 shows the location of these connectors. The SCSI interface includes these features: • Provides one wide Ultra160 SCSI channel • Provides two connectors: – 68-pin VHDCI for the external connection – 68-pin high density for the internal connection • Supports SE and LVD signaling: 16-bit SE or LVD interfaces • Supports LVD/SE termination • Supports Fast, Ultra, Ultra2, and Ultra160 data transfer capability – Ultra160 SCSI LVD synchronous transfers at up to 160 Mbytes/s • Supports Domain Validation, Double Transition (DT) data transfers, and Cyclic Redundancy Check (CRC) • Supports variable block size and scatter/gather data transfers • Protects nondata phases with Asynchronous Information Protection (AIP) • Supports two termination control options: – Use manual shunts on connector J2 and J4 to disable termination – Provide software control using GPIO3 to enable or disable the terminators • Supplies SCSI termination power (TERMPWR) source with autoresetting circuit breaker • Includes SCSI Plug and Play • Provides Flash EEPROM for BIOS configuration storage • Supports RAID ready BIOS for use with Nextreme™ RAID software • Includes 8 Kbytes internal RAM for SCRIPTS instruction storage • Provides a SCSI activity LED connector (J3) Features 1-3 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 • LPPCI and standard ISA/EISA bracket available 1.2.4 SCSI Activity LED Interface The J3 connector is a four-wire arrangement on the LSI20160L 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. 1.3 Ultra160 SCSI Benefits Ultra160 SCSI is an extension of the SPI-3 draft standard that allows faster synchronous SCSI data transfer rates than Ultra2 SCSI. When enabled, Ultra160 SCSI performs 80 megatransfers per second resulting in approximately double the synchronous data transfer rates of Ultra2 SCSI. The LSI53C1000 performs 16-bit, Ultra160 SCSI synchronous data transfers as fast as 160 Mbytes/s. This advantage is most noticeable in heavily loaded systems or large block size applications such as video on-demand and image processing. 1.3.1 Double Transition (DT) Clocking The Ultra160 data transfer speed is accomplished using DT clocking. DT clocking refers to transferring data on both rising and falling edges of the request and acknowledge signals. Double-edge clocking doubles data transfer speeds without increasing the clock rate. 1-4 Describing the LSI20160L 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. CRC, along with AIP, provides end-to-end protection of the SCSI I/O. 1.4 SureLINK™ Ultra160 SCSI Domain Validation Benefits SureLINK software represents the very latest SCSI interconnect management solution. It ensures robust and low risk Ultra160 SCSI implementations by extending the Domain Validation guidelines documented in the ANSI T10 SPI-3 specifications. Domain Validation verifies that the system is capable of transferring data at Ultra160 speeds, allowing it to renegotiate to lower speed and bus width if necessary. SureLINK software is the control for the manageability enhancements in the LSI53C1000. Fully integrated in the SDMS software solution, SureLINK software provides Domain Validation at boot time, as well as throughout system operation. 1.5 LVDlink™ Benefits The LSI20160L supports LVD for SCSI, a signaling technology that increases the reliability of SCSI data transfers over longer distances than are supported by SE SCSI. The low current output of LVD allows the I/O transceivers to be integrated directly onto the chip. LVDlink technology lowers the amplitude of noise reflections and allows higher transmission frequencies. LVD provides a long-term migration path to even faster SCSI transfer rates without compromising signal integrity, cable length, or connectivity. SureLINK™ Ultra160 SCSI Domain Validation Benefits 1-5 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 LSI20160L features TolerANT technology, which includes active negation on the SCSI drivers and input signal filtering on the SCSI receivers. The benefits of TolerANT technology include increased immunity to noise when the signal is going HIGH, better performance due to balanced duty cycles, and improved fast SCSI transfer rates. In addition, TolerANT SCSI devices do not cause glitches on the SCSI bus at power up or power down, so other devices on the bus are also protected from data corruption. When it is used with the LVDlink transceivers, TolerANT technology provides excellent signal quality and data reliability in real world cabling environments. TolerANT input signal filtering is a built-in feature of the LSI53C1000 device as well as all LSI Logic SCSI devices. 1-6 Describing the LSI20160L Chapter 2 Installing the LSI20160L This chapter provides instructions on how to install the LSI20160L 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.

If you are experienced in these tasks, you may prefer to use 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 SCSI host adapter that you install can act as host for up to 15 peripheral devices, not including the adapter itself. 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. 2-2 Installing the LSI20160L Step 1. Ground yourself before removing the host adapter board from its package. Step 2. Remove the LSI20160L from its packing and verify it is not damaged. Figure 2.1 shows an example of this host adapter board. Refer also to Figure 3.1 for a more detailed drawing. Step 3. Switch off and unplug the system. Step 4. 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; do not touch board components or gold connector contacts. The use of a static ground strap is recommended. Step 5. Locate the PCI slots on your computer. Refer to the user’s manual supplied with your computer to confirm the location of the PCI slots. Also, the LSI20160L requires a PCI slot that allows bus master operation and provides 3.3 Volts. Figure 2.2 is a representative drawing of a computer mainboard. Detailed Installation Procedure 2-3 2.2.3 Inserting the Host Adapter Perform the following steps to install the LSI20160L 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. Refer to Figures 2.1 and 2.2. Figure 2.1 Hardware Connections for the LSI20160L Busy LED Connector J3 68-pin Internal High Density SCSI Connector J4 68-pin VHDCI External SCSI Connector J2 Note: 2-4 LSI20160L to PCI Bus Edge Connector J1 You may notice that the components on a PCI host adapter face the opposite way from non-PCI adapter boards you have in your system. This is correct. The board is keyed to go in only one way. Installing the LSI20160L 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. Figure 2.2 Inserting the Host Adapter 32-bit slot 64-bit slots Detailed Installation Procedure 2-5 2.2.4 Connecting SCSI Peripherals All internal SCSI bus connections to the LSI20160L 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. All external SCSI bus connections to the LSI20160L are made with shielded, 68-conductor cables (see Figure 2.3). The connectors on this cable are always keyed to ensure proper pin-1 connection. Figure 2.3 SCSI Cables SCSI Cable for Internal Connections 68-pin High Density SCSI Cable for External Connections 68-pin VHDCI 2-6 Installing the LSI20160L 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 2.4 Internal SCSI Ribbon Cable to Host Adapter Detailed Installation Procedure 2-7 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. 2-8 Installing the LSI20160L 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 2-9 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. 2-10 Installing the LSI20160L The Busy LED connector J3 is not keyed. The J3 connector is a 4-pin one row right angle header. Some LED cables have only two wires. In this case, place the connector on one end of J3. If the LED does not light during SCSI bus activity, you may have to rotate the LED cable 180˚ on J3 or move it to the other end of the jack. 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 2-11 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 2.9 2-12 External Cable to Host Adapter Installing the LSI20160L 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 2-13 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 LSI20160L 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. When the shunt is off, the terminator is active. When the shunt is on the post, the terminator is disabled. • Termination can be enabled or disabled for a specific channel using software control with GPIO3. LVD peripheral devices are normally terminated with external terminators, but are sometimes 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 for information on how to identify the terminator setting of each device and how to change it. The LSI20160L automatically controls SCSI bus termination for two different bus configurations (see Figure 2.1). The two bus configurations are: • Termination on • Termination off You can disable termination in two ways: • Use BIOS software control, where the BIOS termination option is changed from Automatic to Off. • Manually place a shunt on the post of the respective jumpers, J2DIS and J4DIS. Detailed Installation Procedure 2-15 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 2.12 Internal SCSI Device Termination Last Device on Chain-Termination Enabled Does Not End Chain-Termination Disabled Host Adapter Automatically Terminated 2-16 Installing the LSI20160L 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 2.13 External SCSI Device Termination Last Device on Chain-Termination Enabled Does Not End Chain-Termination Disabled Host Adapter Automatically Terminated Detailed Installation Procedure 2-17 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 4.0 User’s Guide explains how to set your host adapter ID using the SCSI BIOS Configuration Utility. 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. Step 1. Determine the SCSI ID of each device on the SCSI bus. Note any duplications. Step 2. Make any necessary changes to the SCSI IDs and record the IDs for future reference. Correct any duplications at this time. Table 2.1 on page 2-19 is provided as a place to keep this record. 2-18 Installing the LSI20160L Table 2.1 SCSI ID SCSI ID Record SCSI Device 15 14 13 12 11 10 9 8 7 LSI20160L (default) 6 5 4 3 2 1 0 Detailed Installation Procedure 2-19 2.3 Completing the Installation Before replacing the cover on your computer, review this installation procedure check list.
