The PCI interface operates as a 64-bit DMA bus master capable of 64-bit addressing. The LSI53C1010 contains the PCI functionality for the LSI21040. The PCI interface includes these features: • Complies with PCI 2.2 specification • Complies with PCI Bus Power Management Specification Rev 1.1 • Complies with PC99 • Supports up to 64-bit/33 MHz PCI interface for 264 Mbytes/s bandwidth that: – Supports 64-bit DMA bus mastership with 64-bit addressing – Operates at 33 MHz 48.583 pc 1-2 Using the LSI21040 52.5 pc 3.75 pc 10.25 pc 11.25 pc 38.25 pc 34.5 pc – Supports dual address cycle generation for all SCRIPTS – Presents a single electrical load to the PCI Bus (True PCI Multifunction Device) 4.333 pc • Bursts 2 to 128 Dwords across the PCI bus • Supports 32-bit or 64-bit word data bursts with variable burst lengths • Supports the PCI Cache Line Size register • Prefetches up to 8 Dwords of SCRIPTS instructions • Supports PCI Write and Invalidate, Read Line, and Read Multiple commands • Bursts SCRIPTS opcode fetches across the PCI bus • Supports universal 3.3 V and 5 V PCI signaling environment 1.2.2 SCSI Interface 44.25 pc The SCSI interface on the LSI21040 operates as an 8-bit or 16-bit interface. It supports 8-bit or 16-bit, synchronous and asynchronous, LVD or SE, Fast, Ultra, Ultra2, and Ultra160 SCSI protocols in various combinations. The LSI53C1010 contains the SCSI functionality for the LSI21040. This chip is a PCI to Ultra160 SCSI Controller with LVD Link™ Universal Transceivers. It connects directly to the SCSI bus and generates signal timing and bus protocol in compliance with SCSI standards. The SCSI interface includes these features: • Performs wide, Ultra160 SCSI synchronous data transfers as fast as 160 Mbytes/s using Double Transition (DT) clocking for Channel A • Performs wide, Ultra SCSI SE synchronous transfers as fast as 40 Mbytes/s for Channel B • Enables LVD or SE termination on Channel A automatically • Enables SE termination on Channel B automatically • Contains internal 68-pin high density connectors for Channel A and Channel B • Contains internal ribbon connector 50-pin for Channel B • Contains external connector 68-pin high density for Channel A 48.583 pc Features 1-3 52.5 pc 3.75 pc 10.25 pc 11.25 pc 38.25 pc 34.5 pc • Provides SCSI termination power (TERMPWR) source with autoresetting circuit protection device • Includes 8 Kbytes internal RAM for SCRIPTS instruction storage for each channel • Supports SCSI Plug and Play • Supports variable block size and scatter/gather data transfers • Performs complex bus sequences without interrupts, including restore data pointers • Contains a serial EEPROM for user configuration utility • Provides SCSI bus activity LED connector for each channel on one connector 4.333 pc 1.2.3 Board Characteristics The LSI21040 characteristics are: 44.25 pc • PCI board dimensions: 152.4 x 88.90 mm (6.875 x 3.99 inches) • PCI Universal 64-bit card edge connector • One high density 68-pin external connector • Two high density 68-pin internal connectors • One 50-pin internal ribbon connector • SCSI Bus Activity LED connector In Chapter 3, “Specifying the Technical Characteristics,” Figure 3.1 illustrates the mechanical drawing for this host adapter board. 1.2.4 SCSI Bus Activity LED Connector A SCSI Bus Activity LED connector indicates the status of the SCSI bus when an LED is attached. This LED lights when the SCSI bus is transferring information. 48.583 pc 1-4 Using the LSI21040 52.5 pc 3.75 pc 10.25 pc 11.25 pc 38.25 pc 34.5 pc 4.333 pc 1.3 Benefits of Ultra160 SCSI Ultra160 SCSI delivers data up to two times faster than Ultra2 SCSI. Ultra160 SCSI is a subset of the SCSI Parallel Interface-3 (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 LSI53C1010 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 Ultra160 SCSI includes DT clocking in order to double data transfer speeds without increasing the clock rate. As a result, data is clocked on both rising and falling edges of the Request and Acknowledge signals. 1.3.2 Cyclic Redundancy Check (CRC) 44.25 pc Ultra160 SCSI includes CRC to provide data bus protection. CRC 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, all double bit errors, or any combination of errors within a single 32-bit range. 1.3.3 Domain Validation Ultra160 SCSI also includes Domain Validation to provide basic integrity checking. Domain Validation is a procedure that allows a host computer and target SCSI peripheral to negotiate and find the optimal transfer speed. This procedure improves overall reliability of the system. SURElink™ extends this feature by providing three levels of integrity checking. Refer to Section 1.6, “Benefits of SURElink (Extended Domain Validation),” on page 1-7 for more detailed information. 48.583 pc Benefits of Ultra160 SCSI 1-5 52.5 pc 3.75 pc 10.25 pc 11.25 pc 38.25 pc 34.5 pc 1.3.4 Asynchronous Information Protection (AIP) 4.333 pc The LSI53C1010 supports AIP to protect all non-data phases, including command, status, and messages. CRC, along with AIP, provides end-toend protection of the SCSI I/O. 1.4 Benefits of LVD Link Technology To support greater device connectivity and a longer SCSI cable, the LSI21040 features LVD Link technology, the LSI Logic implementation of Universal LVD SCSI. LVD Link transceivers provide the inherent reliability of differential SCSI, and a long-term migration path to faster SCSI transfer rates. The LVD Link transceivers reduce the power needed to drive the SCSI bus, so that the I/O drivers can be integrated directly into the chip. LVD Link technology lowers the amplitude of noise reflections and allows higher transmission frequencies. The LVD Link transceivers operate in LVD and SE modes. They also allow the chip to detect a High Voltage Differential (HVD) signal when the chip is mistakenly connected to external HVD transceivers. When connected, the LSI53C1010 automatically detects signal type, based on the voltage detected. It automatically switches to the SE or LVD mode, as appropriate. 44.25 pc Important: All bus devices must be LVD or SE. If a HVD device is detected, the board puts the SCSI bus in the high impedance state and shuts down. 1.5 Benefits of TolerANT® Technology The LSI53C1010 features TolerANT technology, which includes active negation on the SCSI drivers and input signal filtering on the SCSI receivers. Active negation causes the SCSI Request, Acknowledge, Data, and Parity signals to be actively driven HIGH rather than passively pulled up by terminators. 48.583 pc 1-6 Using the LSI21040 52.5 pc 3.75 pc 10.25 pc 11.25 pc 38.25 pc 34.5 pc TolerANT receiver technology improves data integrity in unreliable cabling environments where other devices would be subject to data corruption. TolerANT receivers filter the SCSI bus signals to eliminate unwanted transitions, without the long signal delay associated with RC-type input filters. This improved driver and receiver technology helps eliminate double clocking of data, which is the single biggest reliability issue with SCSI operations. TolerANT input signal filtering is a built-in feature of the LSI53C1010 and all LSI Logic Fast SCSI, Ultra SCSI, Ultra2 SCSI, and Ultra160 SCSI devices. 4.333 pc The benefits of TolerANT technology include increased noise immunity when the signal transitions to 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. This technology protects other devices on the bus from data corruption. When it is used with the LVD Link transceivers, TolerANT technology provides excellent signal quality and data reliability in real world cabling environments. TolerANT technology is compatible with both the Alternative One and Alternative Two termination schemes proposed by the American National Standards Institute. 44.25 pc 1.6 Benefits of SURElink (Extended Domain Validation) SURElink 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 is the software control for the manageability enhancements in the LSI53C1010. Fully integrated in the SDMS software solution, SURElink provides Domain Validation at boot time as well as throughout system operation. SURElink extends to the Distributed Management Interface (DMI) based System Management components of SDMS, providing the network administrator remote management capability. SURElink Domain Validation provides three levels of integrity checking: Basic (level 1), Enhanced (level 2), and Margined (level 3). The basic check consists of an inquiry command to detect gross problems. The 48.583 pc Benefits of SURElink (Extended Domain Validation) 1-7 52.5 pc 3.75 pc 10.25 pc 11.25 pc 38.25 pc 34.5 pc enhanced check sends a known data pattern using the Read and Write Buffer commands to detect additional problems. The margined check verifies that the physical parameters have some degree of margin. 4.333 pc By varying LVD drive strength and REQ/ACK timing characteristics, level 3 verifies that no errors occur on the transfers. These altered signals are only used during the diagnostic check and not during normal system operation. Should errors occur with any of these checks, the system can drop back to a lower transmission speed, on a per-target basis, to ensure robust system operation. 44.25 pc 48.583 pc 1-8 Using the LSI21040 52.5 pc 3.75 pc 10.25 pc 11.25 pc 38.25 pc 34.5 pc 4.333 pc Chapter 2 Installing the LSI21040 This chapter provides instructions on how to install the LSI21040 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 2-25 • Section 2.4, “Troubleshooting,” page 2-26 12 pc 12.938 pc 13.851 pc 2.1 Quick Installation Procedure 34.732 pc This section provides an overview of the installation procedure.

If you are experienced in these tasks, you may prefer to use Section 2.1, “Quick Installation Procedure.” 44.25 pc 2.2.1 Before You Start Before starting, look through the following task list to get an overall idea of the steps you will be performing. If you are not confident you can perform the tasks as described here, LSI Logic recommends 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. They 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. Follow the detailed instructions in the next section to successfully install your host adapter board. 2.2.2 Inserting the Host Adapter For safe and proper installation, you will need the user’s manual supplied with your computer. Perform the following steps to install the LSI21040. 48.583 pc 2-2 Installing the LSI21040 52.5 pc 3.75 pc 10.25 pc 11.25 pc 38.25 pc 34.5 pc 4.333 pc Step 1. Ground yourself before removing this host adapter board. Step 2. Remove the LSI21040 from the packing and check that it is not damaged. Figure 2.1 illustrates an example of this host adapter board. Also refer to Figure 3.1 to see a more detailed drawing of this board. Step 3. Switch off the computer and unplug power cords for all components in your system. Step 4. Remove the cover from your computer per the instructions in the user’s manual for your system to access the PCI slots. Caution: Ground yourself by touching a metal surface before removing the cabinet top. 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 slots for PCI plug-in board installation. 44.25 pc Refer to the user’s manual for your computer to confirm the location of the PCI slots. The LSI21040 requires a 32-bit or 64-bit PCI slot that allows bus master operation. If a 32-bit PCI slot is used, bits [31:0] of the J1 connector are inserted while bits [63:32] remain uninserted. See Figure 2.2. Note: For the LSI21040 to function as a 64-bit device, it must be inserted in a 64-bit PCI slot. If the LSI21040 is inserted in a 32-bit PCI slot, it will function as a 32-bit device. Step 6. Remove the blank bracket panel on the back of the computer aligned with the PCI slot you intend to use. Save the bracket screw. 48.583 pc Detailed Installation Procedure 2-3 52.5 pc 3.75 pc 10.25 pc 11.25 pc 38.25 pc 34.5 pc Figure 2.1 4.333 pc Hardware Connections for the LSI21040 Channel B 68-Pin Internal High Density SCSI Connector J2 Channel A and B Busy LED Connector J6 Channel A 68-Pin Internal High Density SCSI Connector J4 Channel B 50-Pin Low Density SCSI Connector J5 44.25 pc 68-Pin External High Density SCSI Connector J3 LSI21040 PCI Bus Edge Connector J1 Step 7.

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. Remember that the LSI21040 is also on the SCSI bus—its termination is automatically enabled when it is connected to the end of the bus. Important: To utilize Ultra2 and faster SCSI performance, you must only have LVD devices on the bus. Do not mix any SE devices with LVD devices or the entire bus will drop to SE, limiting bus performance to Ultra SCSI levels. The peripheral device terminators are usually set with jumpers, resistor modules, 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 type/setting for each device and how to set/change it. Caution: 44.25 pc The autoenable/disable sensing feature on the LSI21040 may enable termination erroneously if it is directly cabled to another SCSI device or host adapter using the same sensing method. The LSI21040 senses the presence of SCSI devices by detecting the ground signal on conductor 50 of the 68-pin SCSI cable and conductor 22 on the 50-pin SCSI cable. The LSI21040 automatically controls SCSI bus termination for three different bus configurations, depending on how it is connected (see Figure 2.1). The three bus configurations are: • Section 2.2.6.1, “Internal Bus Connections” • Section 2.2.6.2, “External Bus Connections” • Section 2.2.6.3, “Internal and External Bus Connections” Termination on the LSI21040 for these three different bus configurations is discussed below. 48.583 pc Detailed Installation Procedure 2-17 52.5 pc 3.75 pc 10.25 pc 11.25 pc 38.25 pc 34.5 pc 2.2.6.1 Internal Bus Connections 4.333 pc If only internal SCSI device connections to your host adapter have been made, you must terminate the last internal device on the SCSI 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 SCSI hard disk drive on the SCSI bus, that drive should have the lowest SCSI ID on the bus. Typically, SCSI ID 0 is used; however, for system performance optimization, an ID other than 0 (zero) can be used. Refer to Chapter 2 “SCSI BIOS” of the PCI Storage Device Management System SDMS 4.0 User’s Guide about how to set the host adapter ID using the LSI Logic 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. Note: 44.25 pc You must not have any duplication of SCSI IDs 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 to eliminate duplicates and record the IDs for future reference. Table 2.3 provides a place to keep this record. 48.583 pc Detailed Installation Procedure 2-23 52.5 pc 3.75 pc 10.25 pc 11.25 pc 38.25 pc 34.5 pc 4.333 pc Table 2.3 SCSI ID SCSI ID Record SCSI Device Channel A SCSI Device Channel B LSI21040 (default) LSI21040 (default) 15 14 13 12 11 10 9 8 7 6 5 44.25 pc 4 3 2 1 0 48.583 pc 2-24 Installing the LSI21040 52.5 pc 3.75 pc 10.25 pc 11.25 pc 38.25 pc 34.5 pc 4.333 pc 2.3 Completing the Installation Before replacing the cover on your computer, review this installation procedure check list.

Ensure the pin-1 orientation is correct for internal cables. Use a 68-pin high density SCSI cable for external connections. • SCSI Devices – Set each SCSI device and the host adapter to a separate SCSI ID 0 through 15. You must not have any duplication of SCSI IDs on a SCSI bus. The default SCSI ID for the host adapter is SCSI ID 7. • Termination – Automatic termination is enabled when the LSI21040 is connected to the end of the bus. For internal and/or external bus connections, terminate the last internal and/or external device on the SCSI bus. 44.25 pc 48.583 pc 2-26 Installing the LSI21040 52.5 pc Chapter 3 Specifying the Technical Characteristics This chapter provides specific details about the physical environment associated with the LSI21040. This chapter includes these topics: • Section 3.1, “Physical Environment,” page 3-1 • Section 3.2, “Operational Environment,” page 3-4 • Section 3.3, “Subsystem and Subsystem Vendor ID,” page 3-10 3.1 Physical Environment This section provides information about the physical, electrical, thermal, and safety characteristics of the LSI21040. Additionally, this board is compliant with electromagnetic standards set by the FCC. 3.1.1 Physical Characteristics The dimensions of the LSI21040 are 6.875 x 3.99 inches. Edge connector J1 makes the PCI connection. Connectors J4 for Channel A and J2 for Channel B are the 68-pin high density connectors that make the internal SCSI connections. J5 is a 50-pin low density vertical connector for Channel B. Connector J3 is a 68-pin high density connector that makes the external SCSI connection. The J3 connector extends externally to 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. Connector J6 provides connection to the computer’s drive activity LED. This connector is a 4-pin one row right angle header. The left two pins are for Channel A SCSI activity, while the right two pins are for Channel B SCSI activity. LSI21040 PCI to Dual Channel Ultra160 SCSI Host Adapter 3-1 The component height on the top and bottom of the board conforms to the PCI Local Bus Specification Revision 2.2. Figure 3.1 illustrates the details of the LSI21040 mechanical drawing.

Under abnormal conditions, such as a short on SCSI TERMPWR, +5 V current may be higher. At temperatures of at least 25 °C, a current of 4 A is sustained no longer than 30 seconds before the self-resetting TERMPWR short circuit protection device (F1) opens. The PCI PRSNT1/ and PRSNT2/ pins are set to indicate a 15 W maximum configuration. 3-2 Specifying the Technical Characteristics 3.1.3 Thermal, Atmospheric Characteristics The thermal, atmospheric characteristics of the LSI21040 are: • Temperature range: 0 °C to 55 °C (dry bulb) • Relative humidity range: 5% to 90% noncondensing • Maximum dew point temperature: 32 °C The following parameters define the storage and transit environment for the LSI21040: • Storage Temperature: −45 °C to +105 °C (dry bulb) • Relative Humidity Range: 5% to 90% noncondensing 3.1.4 Electromagnetic Compliance The board is designed and implemented to minimize electromagnetic emissions, susceptibility, and the effects of electromagnetic discharge. The board carries the CE mark, VCCI, Canada mark, and meets the requirements of FCC Class B. The board is marked with the FCC self-certification logo. 3.1.5 Safety Characteristics The bare board meets or exceeds the requirements of UL flammability rating 94 V0. The bare board is also marked with the supplier’s name or trademark, type, and UL flammability rating. Since this board is installed in a PCI bus slot, all voltages are below the SELV 42.4 V limit. Physical Environment 3-3 3.2 Operational Environment Use the LSI21040 in PCI computer systems with an ISA/EISA bracket type. The SDMS operates the board, but the design of the board does not prevent the use of other software. An on-board flash memory device is provided to allow BIOS code and open boot code support through PCI and a serial EEPROM for each channel. 3.2.1 The PCI Interface The PCI interface operates as a 64-bit DMA bus master. Edge connector J1 makes the PCI connection, which provides connections on both the front and back of the board. The signal definitions and pin numbers conform to the PCI Local Bus Specification Revision 2.2 standard. Table 3.1 and Table 3.2 show the signal assignments. The on-board +3.3 V regulator provides power to the PCI portion of the LSI53C1010 device. Note: 3-4 The +3.3 V pins are tied together and decoupled with high frequency bypass capacitors to ground. No current from these +3.3 V pins is used on the board. The board derives power from the +5 V pins, directly and through a 3.3 V voltage regulator. The PCI +3 V/+5 V pins are used to differentiate between a 5 V or a 3.3 V PCI environment.

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. SCSI termination power is supplied by the board. Connectors J3 and J4 for Channel A and J2 and J5 for Channel B make the SCSI interface. Refer to Figure 2.1 on page 2-4 to see an example of this interface. J2 and J4 are 68-pin high density right angle connectors for internal SCSI connections. J5 is a 50-pin low density vertical connector. External connector J3 is a shielded 68-pin high density right angle connector exposed in the back panel bracket. LVD/SE dual mode, active termination is provided on the LSI21040 for Channel A. SE SCSI termination is provided for Channel B. The LSI21040 supplies SCSI bus TERMPWR through a blocking diode and a self-resetting 1.5 A short circuit protection device. A 40 MHz oscillator is installed on the LSI21040. This oscillator provides the clock frequency necessary to support Ultra160 SCSI transfers of up to 160 Mbytes/s. Table 3.3 and Table 3.4 show the signal assignments for J2 and J5.
