SCSI bus and generates timing and protocol in compliance with the SCSI standard. The SCSI interface on the LSI8751SP operates as 8-bit or 16-bit, synchronous or asynchronous, SE bus, and supports Ultra SCSI protocols and 16-bit arbitration. The interface is made through two (and only two) of the connectors J2, J3,s and J4.
A 40 MHz oscillator is installed on the LSI8751SP to provide the clock frequency to the LSI53C875J that is necessary to support Wide Fast-20 SCSI transfers of up to 40 Mbytes/s. 1.3.3 Ultra SCSI The LSI8751SP fully supports Ultra SCSI as well as Fast SCSI simultaneously.
Chapter 2 Installing the LSI8751SP This chapter provides instructions on how to install the LSI8751SP and includes these topics: • Section 2.1, “Quick Installation Procedure,” page 2-1 • Section 2.2, “Detailed Installation Procedure,” page 2-3 • Section 2.3, “Completing the Installation,” page 2-26 2.1 Quick Installation Procedure...

Step 4. Locate the slot for installing a PCI plug-in board. The LSI8751SP requires a PCI slot which allows bus master operation. Step 5. Remove the blank bracket panel on the back of the computer aligned with the PCI slot you intend to use. Save the bracket screw.
2.2 Detailed Installation Procedure This section provides step-by-step instructions for installing the LSI8751SP, and connecting it to your SCSI peripherals. If you are experienced in these tasks, you may prefer to use the preceding Section 2.1, “Quick Installation Procedure.” If you are not confident that you can perform the tasks as described here, LSI Logic suggests getting assistance.
Step 1. Ground yourself before removing this host adapter board. Remove the LSI8751SP from the packing and check that it is not damaged. An example of this host adapter board is shown Figure 2.1.

Step 7. The bracket around the connector J3 (see Figure 2.1) should fit where you removed the blank panel. Secure it with the bracket screw (see Figure 2.2) before making the internal and external SCSI bus connections. Installing the LSI8751SP...
2.2.3 Connecting the SCSI Peripherals Internal SCSI bus connections to the LSI8751SP are made with an unshielded, 68 or 50-conductor ribbon cable (see Figure 2.3). One edge of this cable is marked with a color to indicate the pin-1 side. Sometimes the connectors on this cable are keyed to ensure proper pin-1 connection.

Step 5. It is also possible to use both internal connectors (J2 and J4) if you do not attach any external devices to connector J3. An example of this configuration is shown in Figure 2.9. Figure 2.9 Using Both Internal Connectors 2-14 Installing the LSI8751SP...
Step 6. Most PC cabinets are designed with a front panel LED (sometimes already connected to an existing IDE drive). Connect the LED cable to connector J5 on your host adapter, as shown in Figure 2.10. This connection causes the front panel LED to indicate activity on the SCSI bus.
2.2.5 Making External SCSI Bus Connections This section provides step-by-step instructions about making external SCSI bus connections. Step 1. If you need to connect external SCSI devices to the LSI8751SP, plug the 68-pin connector on one end of a shielded external SCSI cable (see Figure 2.3) into the host adapter connector J3...
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. An example of this connection is shown in Figure 2.12. Figure 2.12 External Cable to External SCSI Device Detailed Installation Procedure 2-17...
Step 3. If you wish to connect more than one external SCSI device to your host adapter, you must chain them together with shielded external SCSI cables. An example of these chained connections is shown in Figure 2.13. Figure 2.13 Multiple External SCSI Devices Chained Together 2-18 Installing the LSI8751SP...
SCSI bus must have their terminators active. All other SCSI devices on the bus must have their terminators removed or disabled. Remember that your LSI8751SP is also on the SCSI bus—its termination is automatically enabled when it is connected to the end of the bus.

2.2.10 Internal SCSI Connections for Both Internal Connectors If you have made internal SCSI device connections to both internal connectors (J2 and J4) on the host adapter, you must terminate the internal devices on each end of the SCSI bus. You must disable the termination on all other devices.
Chapter 3, “Configuring the LSI8751SP,” explains how to set your host adapter ID using the LSI Logic SCSI BIOS Configuration Utility. Your 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...
Step 3. Wait for your computer to boot up. Step 4. To change the configuration of your host adapter, see Chapter 3, “Configuring the LSI8751SP.” Finally, refer to the PCI Storage Device Management System SDMS 4.0 User’s Guide (or the guide for the software you use) to load the driver software for your particular operating system.

1. Logical Unit Number. 3.2 Starting the SCSI BIOS Configuration Utility If you have LSI Logic SCSI BIOS Version 4.xx, and it includes the LSI Logic SCSI BIOS Configuration Utility, you can change the default configuration of the SCSI host adapters. You may decide to alter these default values if there is a conflict between device settings or if you need to optimize system performance.
3.2.1 Configuration Utility Main Menu When you start the LSI Logic SCSI BIOS Configuration Utility, the Main Menu appears. This menu displays a list of up to four LSI Logic PCI to SCSI host adapters and information about each of them. To select an adapter, use only the arrow keys and enter key.
Below the list of host adapters on the Main Menu display, you see eight options. They are described in detail below. If these settings are altered, the system reboots upon exit from the Configuration Utility by using the Quit option. Configuring the LSI8751SP...
3.2.1.2 Adapter Boot Order Adapter Boot Order allows the user to set the order in which host adapters will boot when you have more than one LSI Logic host adapter in your system. When this option is selected, the Boot Order menu appears.

Parity – The LSI Logic PCI to SCSI host adapters always generate parity, but some older SCSI devices do not. Therefore, you are offered the option of disabling parity checking. Note: When disabling parity checking, it is also necessary to disable disconnects for all devices, as parity checking for the reselection phase is not disabled.

Spinup Delay (seconds) – This option allows you to stagger spinups for a longer period of time to balance the total current load. The default value is 2 seconds with choices between 1 and 10 seconds. 3-10 Configuring the LSI8751SP...
This is a power management device designed to accommodate disk devices that may have heavy current load during power up. If multiple drives are being powered up simultaneously and drawing heavy current loads, then this option staggers the spinups to limit startup current. 3.2.3 Device Selections Menu When you select the Device Selections option, the corresponding menu (as shown in...

Page 53
Read/Write I/O Time-out (seconds) – This option sets the amount of time the host adapter waits for a read, write, or seek command to complete before trying the I/O transfer again. Since this provides a safeguard allowing the system to recover if an I/O operation fails, it is recommended that you always set the time-out to a value greater than zero.
