CHAPTER 2: Introduction

2. Introduction

The Ultra2 LVD SCSI Host Adapter (our product code IC515C) is a highperformance Ultra2 SCSI (Low Voltage Differential) PCI-busmastering adapter that functions as the interface between a SCSI bus and a PC’s PCI local bus. The Adapter supports all kinds of peripherals compatible with SCSI-1, SCSI-2, Fast SCSI, Ultra SCSI, or Ultra2 SCSI (LVD), including I/O devices such as SCSI scanners and storage media such as hard-disk, CD-ROM, MO, tape, and removable drives.

2.1 Features

• PCI 2.1 compliance. The Adapter meets all the latest electrical, mechanical, and protocol specifications for the PCI bus.

• Full SCSI compliance. The Adapter is fully Ultra2 SCSI compliant, supporting advanced features such as tag queueing, sync/async transfers, and disconnect/reselect arbitration.

• Plug-and-Play support. The Adapter’s onboard ROMs can handle installation, configuration, and booting without requiring user intervention.

• Use of only one system IRQ. The Adapter doesn’t hog your system’s limited resources.

• 32-bit data transfers between the Adapter and the host PC at up to 133 megabytes per second in PCI burst mode. The PCI bus is a 32-bit bus; when it runs synchronously at 33 MHz, the Adapter achieves a peak sustainable operating speed of 133 MB per second.

• Regular (synchronous) SCSI data rates up to 80 megabytes per second, and

asynchronous SCSI data rates up to 10 megabytes per second.

• Compatible with all types of standard SCSI peripherals. Hard drives, CD-ROM drives, tape drives, printers, scanners—it doesn’t matter what types of peripherals you want to hook to the Adapter. As long as they’re compliant with Ultra2 SCSI (LVD), Ultra SCSI, Fast SCSI, SCSI-2, or SCSI-1, they should work.

• Support for hard-drive capacities up to 8 GB. With the Adapter, MS-DOS

hard-disk limitations can be extended from 1 GB to 8 GB.

ULTRA2 LVD SCSI HOST ADAPTER

• User-hardwirable, user-programmable, or automatic SCSI termination. You can choose between hardwire-enabling termination on the Adapter, programming the termation through its firmware, or letting the Adapter handle termination automatically, eliminating the need to open up the PC every time you need to make termination changes.

• Onboard BIOS supports Microsoft

MS-DOS. The Adapter has the necessary

software onboard to handle MS-DOS disk-drive operations without requiring additional system-based drivers.

• Support for all other major operating systems. The Adapter includes drivers for Windows

98, Windows 95, Windows NT, IBM®OS/2®, Novell®NetWare®,

SCO

UNIX®, SCO UnixWare®, and Linux®.

• SmartSCSI™ Setup Utility program. You can use this firmware utility to customize the Adapter’s configuration. Unless you need to hardwire termination, you don’t have to set any jumpers at all.

• Built-in Integrated Scatter/Gather Engine (ISGE™). This hardware circuitry heightens performance in all scatter/gather operations.

• 256-byte FIFO. The Adapter uses a 256-byte FIFO caching buffer to manage PCI-to-SCSI-bus structure timing for data and command transfer.

• Command queueing. With this special feature, the Adapter can process as many as 255 simultaneous SCSI commands.

NOTE

The README.TXT file on Driver Disk 1 might contain updates, corrections, and additions to the information in this manual. However, if you consult this file, you need to keep in mind that it was written by the company that developed the drivers for use with the Ultra2 LVD SCSI Host Adapter, and they use their own “INI-

A100U2W” code (rather than

“IC515C”) to refer to the Adapter.

CHAPTER 2: Introduction

2.2 The Adapter Illustrated

The Ultra2 LVD SCSI Host Adapter and its major components are shown in Figure 2-1 below. You might want to refer to this diagram as you install your Adapter (see Chapter 4). Figure 2-2 below that shows closeups of the Adapter’s two SCSI connectors. The Adapter’s other components include:

• Jumper JP1: These posts are usually left open so that termination can be firmware-controlled. Put a jumper on them to hard-wire termination always ON.

•

SE LED: Lights if any single-ended (legacy) devices are attached to the Adapter.

• LVD LED: Lights if any Ultra2 LVD SCSI devices are attached to the Adapter.

• ACT LED: Dark if the attached SCSI bus is passively terminated (which we don’t recommend); lights if the bus is actively terminated (including forcedperfect termination).

3. Before You Install: Getting Started

3.1 The Adapter and the SCSI Bus

Your Ultra2 LVD SCSI Host Adapter performs busmastering and works with the host computer to provide a means of control for the SCSI bus. By daisychaining peripheral devices together, as many as fifteen devices can be linked to the Adapter on the SCSI bus. The Adapter does not have to be placed in any particular physical position on the bus, but because it doesn’t have two external connectors, it has to be at the end of any all-external bus.

SCSI devices communicate on the bus using bus arbitration, which gives each device an opportunity to use the bus based on the device’s priority (which is determined by the device’s ID, not its physical location). The Adapter is factorypreset to ID 7, the ideal ID for it on a single-adapter bus (see the next section).

3.2 SCSI ID Numbers

Each internal or external device attached to the Ultra2 LVD SCSI Host Adapter, as well as the Adapter itself, must have a unique SCSI ID number. This SCSI ID determines priority when two or more devices are trying to use the SCSI bus at the same time. No two devices can have the same ID; the SCSI ID uniquely defines the device to the SCSI bus.

The Ultra2 LVD SCSI Host Adapter is factory-preset to use SCSI ID 7, which gives it the highest priority on the SCSI bus; this ID number should not be changed. IDs are usually assigned to each peripheral device at the factory, but you will be able to set them to whatever you need them to be. This is usually done with jumpers, DIP switches, or other physical controls; refer to each peripheral’s documentation to determine how to set its ID. The key thing to remember is that no two devices on the same SCSI bus can have the same ID; each ID must uniquely identify a single device. Also keep in mind that a device’s SCSI ID does not necessarily have any relationship to its physical location or its position on the bus. For example, you can have an internal SCSI peripheral with ID 0, and an external SCSI peripheral with ID 6. (Gaps in the number sequence don’t matter either.)

CHAPTER 3: Before You Install: Getting Started

A device’s ID number will reflect the priority it has on the SCSI bus; except for ID 7 (reserved for host adapters), the lower a device’s number, the higher its priority. So you should assign lower numbers to the devices that you will need to access more frequently or at a moment’s notice, and higher numbers to less critical devices. (8-bit “Narrow” SCSI peripherals must use SCSI IDs 0 through 6; 16-bit “Wide” peripherals can be assigned IDs 8 through 15 as well.) Here’s an example setup:

0 Primary hard drive

1 Secondary hard drive

2 CD-R drive

3 DVD drive

4 Floppy drive

5 Tape drive

6 SCSI scanner

7 SCSI host adapter

15 (Other, low-priority SCSI peripherals)

When you assign SCSI IDs, we recommend that you leave the Ultra2 LVD SCSI Host Adapter set for ID 7, its factory-default setting; use the Adapter’s firmware configuration utility if you must change the ID number (see Section 4.6.4). If you plan to boot your system from a SCSI hard-disk drive, set that drive to ID 0 for best operation with most operating systems. (Most hard drives come from the factory preset to ID 0.) Set the second hard drive, if you’re using one, to ID 1, and set additional peripherals to sequentially higher IDs.

You can use the Windows 95 or 98 Device Manager to view the SCSI ID (and other system-configuration parameters) assigned to each SCSI device attached to a Windows 95 or 98 PC. You can do the same thing through just about any operating system by accessing the Adapter’s SmartSCSI utility.

ULTRA2 LVD SCSI HOST ADAPTER

3.3 SCSI-Bus Length

Because of its inherent electrical vulnerability as a high-speed parallel interface, the SCSI bus has definite distance limitations. With earlier versions of the SCSI interface, the maximum length of the bus—the total distance from the terminated device at one end to the terminated device at the other end—were normally inversely proportional to the data rate, as shown below:

Max. Length Standard

6 m (19.7 ft.) SCSI-1 6 m (19.7 ft.) Fast SCSI (SCSI-2) 3 m (9.8 ft.) Ultra SCSI (SCSI-3), up to 4 devices

1.5 m (4.9 ft.)

Ultra SCSI (SCSI-3), up to 7 devices (narrow) or 15 devices (wide)

Ultra2 SCSI, however, can be extended to distances as great as 12 m (39.4 ft.) with the proper cabling, as long as all of the devices are Ultra2 compliant, or even as far as 25 m (82 ft.) to a single Ultra2 device. (If any attached devices are not Ultra2 compliant, the bus speed drops to that of the slowest SCSI interface represented by a device on the bus, and the maximum distance drops to that of the most lengthrestricted SCSI interface represented by a device on the bus.) Remember that if you attach both internal and external devices to the Adapter, the bus goes from the last internal device to the last external device. To make sure you can run the greatest possible distance, make sure to use cable with impedance of at least 120 ohms (do not use 90-ohm cable unless all of the devices you’re attaching are non-Ultra2 LVD type); use high-quality twisted-pair cable with high-quality shielded connectors for your external cable.

3.4 SCSI-Bus Termination

To ensure reliable communication, the SCSI bus must be properly “terminated.” That is, the bus must be bracketed with networks of electrical resistors called “terminators” that absorb the remains of data signals and prevent them from echoing and interfering with fresh signals. Unless they are actually built into the cables, terminators must be placed—or enabled, if the last devices have them built in—at the two extreme ends of the SCSI bus. All devices that lie between the ends must have their terminators removed or disabled. SCSI cabling is designed to be connected in daisychain fashion, with no device on the bus being directly connected to more than two others. No branching is permitted on the SCSI bus. Refer to the example setups in Figure 3-1 on the next page.

ULTRA2 LVD SCSI HOST ADAPTER

Because the methods for terminating SCSI peripherals can vary widely, you should refer to a given peripheral’s documentation for instructions on how to enable or disable its termination. Here are some general tips about device termination, though:

• Internal Ultra2 SCSI peripherals are shipped from the factory with termination disabled; this setting cannot be changed. Proper termination for internal Ultra2 peripherals is always provided by a built-in connector at the end of the attached internal Ultra2 SCSI cable.

• On other kinds of internal SCSI peripherals, termination is usually controlled by manually setting a jumper or moving a switch on the unit, or by physically installing or removing one or more resistor modules on the unit.

• On external SCSI peripherals of all kinds, termination is usually controlled by installing or removing a SCSI terminator, although some peripherals have internal termination that you can switch on or off instead.

• Most non-Ultra2 SCSI peripherals come from the factory with termination enabled.

As it is shipped from the factory, your Ultra2 LVD SCSI Host Adapter can automatically enable or disable its built-in termination. If the Adapter senses that it is at the end of the bus—for example, if you attach only internal or only external SCSI devices to it—it will auto-terminate itself. If it senses that it is in the middle of the bus—for example, if you attach both internal and external SCSI devices to it— it will auto-disable its terminators.

If you would rather set the Adapter’s termination manually, you can go into the SmartSCSI™ Setup Utility in the Adapter’s firmware (see Section 4.6.4) and change the “SCSI Terminators” setting in the “Adapter Setup” menu. Switch from “Automatic” to either “ON” (always ON), “OFF” (always OFF), or a combination of “High bit ON”/“OFF” and “Low bit ON”/“OFF”:

• Set the high bit and low bit both ON if the Adapter is at the end of the bus, so that only external devices or only internal devices are attached.

•

Set the high bit and low bit both OFF if the Adapter is in the middle of the bus, so that both internal and external devices are attached, and if at least one device on each side (internal and external) is a Wide SCSI (68-pin, 16-bit) device.

• Set the high bit ON and the low bit OFF if the Adapter is in the middle of the bus, so that both internal and external devices are attached, and if all of the devices on either or both sides (internal and external) are Narrow SCSI (50-pin, 8-bit) devices.

CHAPTER 3: Before You Install: Getting Started

NOTE

If you mix Wide and Narrow devices on the same side (internal or external) of a SCSI bus attached to the Adapter, we strongly recommend that all of the Narrow devices be attached to the bus closer to the Adapter than all of the Wide devices. If you attach any Narrow devices at the far end of the bus, beyond any Wide devices, you’ll have to be very careful to terminate the Wide lines (Pins 51 to 68) of the last Wide device.

Alternatively, you can “hardwire” the Adapter so that termination is always ON by installing jumpers on the Adapter’s circuit board. The most common application for which you would hardwire-enable termination is this: installing multiple Adapters in multiple PCs, but attaching them to the same bus in order to share peripherals. In such situations, you might want to hardwire termination ON for any Adapters that are on the end of the bus, so that you can turn off the computers in which those Adapters are installed without losing termination power and disabling the SCSI bus. If for this (or whatever) reason you do want to hardwire termination ON, you need to install a jumper on the Adapter before you put it in your PC. (Once this jumper is installed, it will override the termination setting in the Adapter’s firmware.) The jumper should be installed at location JP1, as shown in Figure 3-3 below.

ULTRA2 LVD SCSI HOST ADAPTER

3.5 Attaching Legacy Equipment

Your Ultra2 LVD SCSI Host Adapter supports legacy (non-Ultra2) peripheral devices. However, we recommend that you attach only Ultra2 LVD devices to the Adapter. This is because, if you do attach any other type of SCSI device, the bus will become limited to (a) the speed of the slowest device and (b) the length supported by the least distance-tolerant device.

3.6 The Complete Package

Your complete Ultra2 LVD SCSI Host Adapter package includes the following:

• The Adapter card itself.

• A 125-cm (4.1-ft.) 68-pin internal “Wide SCSI” ribbon cable.

• Two diskettes containing driver software.

• This manual.

If anything is missing, contact Black Box right away. If the package has been damaged, contact both Black Box and the shipping carrier.

CHAPTER 4: Installation and Configuration

4. Installation and Configuration

This chapter describes how to install and configure your Ultra2 LVD SCSI Host Adapter. (If you are installing multiple Adapters in a clustered system, refer to Section 4.5.) If you have any difficulty, please refer to Section 6.1.

4.1 Installing the Adapter Itself

Follow these instructions to install your Ultra2 LVD SCSI Host Adapter:

NOTE

If you’re running Windows NT on the computer you’ll be installing the Adapter in, you might want to install the driver before you install hardware. If so, follow the procedure listed in Section 5.4.

1. Turn OFF your computer, unplug it, and disconnect it from all other devices.

2. Take precautions to keep from damaging the Adapter with any accidental static discharge.

At the very least, discharge yourself on a metal part of the PC chassis or on some other metallic surface before touching the Adapter. If possible, stand on an anti-static mat and wear a grounding strap or anti-static gloves.

3. (Optional) If you need to hardwire termination on the Adapter so that it’s always enabled (ON), install the necessary jumper(s) on the Adapter if you haven’t done so already. See Section 3.4.

4. Remove the cover from the computer case.

5. Locate an unused 32-bit PCI expansion slot (the slot must support busmastered data transfers). PCI slots are shorter than ISA or EISA slots and are typically white. Usually there are several of them on the motherboard. (One of these might be a shared slot into which you can insert either an ISA/EISA board or a PCI board.) Refer to your PC’s documentation if you’re still not sure which ones are the PCI slots.

Once you’ve located a PCI slot, unscrew and remove the metal bracket that covers the card-slot opening. (Save the screw; you will be using it to secure the host adapter in your computer.)

6. Holding the SCSI Host Adapter by the mounting bracket and card edge, with it oriented so that the external connectors are facing the right way, insert the Adapter in the PCI slot. Press it down firmly so the contacts are securely seated in the slot. See Figure 4-1 on the next page.

CAUTION!

Though the PCI connector is keyed to prevent cards like the Adapter from being inserted incorrectly, it is possible to damage the Adapter by forcing it into other types of connectors.

Figure 4-1. Inserting the Adapter in a PCI slot.

7. When the Adapter is firmly seated, secure its metal bracket to the PC’s chassis with the screw you removed in step 3.

8. (Optional) Most computers have one or more hard-drive-activity LEDs on their front panel. If you want to, you can use your own cabling (because we do not include cables for this purpose) to attach one of these indicators to the Adapter’s four-pin LED connector, J3 (see Figure 3-2 on page 19 and Figure 4-2 on the next page). Once you do so, the LED will light whenever there is activity involving the attached Adapter anywhere on the SCSI bus.

aCHAPTER 4: Installation and ConfigurationCHAPTER

9. Most PCI-bus computers will automatically assign the Adapter an I/O address, IRQ channel, and BIOS address. If this is not the case with your system, you’ll have to do this manually, either by setting jumpers on the PC’s motherboard (which you can do now; refer to your PC’s documentation) or changing the settings of the PC’s CMOS BIOS (you’ll have to do this later—see Section 4.3). (If the PC will be booting from a SCSI drive attached to the Adapter, you might also need to change the drive-type setting in the PC’s BIOS, because it might be expecting the boot drive to be an IDE drive.)

10. If you are attaching any internal SCSI devices to the Adapter, go on to Section 4.2. Otherwise, replace the PC’s cover, reconnect all devices, plug the PC back in, and go on to Section 4.3.

4.2 Attaching Other SCSI Devices to the Adapter’s Bus

You can connect as many as fifteen internal and external SCSI devices to your Ultra2 LVD SCSI Host Adapter. Follow the directions listed in this section. (If you are connecting SCSI devices to multiple Adapters to form a clustered system, refer to Section 4.5.)

EVICES

If you are connecting internal SCSI devices, make sure to use a SCSI ribbon cable that (a) is not too long (see Section 3.3), (b) has the appropriate characteristics (see Section 3.3), and (c) has enough connectors to accommodate the Adapter and all of your internal peripherals. Figure 4-3 below shows the preterminated Wide (68-pin) internal cable that comes with the Adapter; it has enough connectors for four internal SCSI devices.

Figure 4-3. The Adapter’s included internal ribbon cable.

This cable is 125 cm (4.1 ft.) long; whether you use it or some other cable, keep in mind that the total length of cable on the Adapter’s SCSI bus, including both internal and external cables, mustn’t exceed 12 m (39.4 ft.) unless you’re attaching one and only one peripheral, in which case you can run as far as 25 m (82 ft.). And this assumes that all of your devices are Ultra2 SCSI LVD compliant; if you are attaching any legacy devices, the maximum total bus length will be much less:

• 6 m (19.7 ft.) if the only legacy devices attached to the bus are SCSI-1 or Fast SCSI (SCSI-2) devices.

• 3 m (9.8 ft.) if you have four or fewer devices attached to the bus and any of them are Ultra SCSI (SCSI-3) devices.

• 1.5 m (4.9 ft.) if you have five or more devices attached to the bus and any of them are Ultra SCSI (SCSI-3) devices.

The cable should have an impedance of at least 120±8 ohms if any Ultra2 SCSI LVD devices are attached; the impedance can be as low as 90±8 ohms only if all attached devices are non-Ultra2-type.

CHAPTER 4: Installation and Configuration

Take these steps to connect internal SCSI devices to the Adapter:

1. If you haven’t already done so, turn OFF and unplug the PC, disconnect all other devices from it, and remove its cover.

2. If you haven’t already done so, prepare each internal SCSI peripheral for installation: configure the device’s SCSI ID and termination. (If you’ll be using the included cable, or some other preterminated cable, all of the devices should have termination turned OFF. If you’ll be using a non-terminated cable, turn the last device’s termination ON and leave the others OFF.) For instructions, see the device’s documentation as well as Sections 3.2 and 3.3.

3. Install each internal SCSI peripheral in your computer. Refer to your computer’s and peripherals’ documentation for instructions.

4. Plug one end of your internal SCSI cable into the Adapter’s appropriate internal SCSI connector. (If you’re using the cable included with the Adapter, plug in the unterminated end.) Make sure the colored stripe that runs the length of one edge of the cable is aligned with Pin 1 of the Adapter’s connector. The cable should be keyed for proper insertion. Figure 4-4 below shows how to plug in this cable.

Figure 4-4. Plugging a narrow internal cable into the Adapter.

5. Plug the internal cable’s other connectors into the internal SCSI peripherals that you installed in step 3. (If you are using the cable included with the adapter, or some other cable with 68-pin connectors, and any of the peripherals are Narrow [50-pin] devices, you will need to attach 50-pinfemale-to-68-pin-female adapters, such as our product code EVNSCT38, between the cable and the device.) Also attach internal power cables to any of these devices that get their power from the PC. Refer to the instructions for doing these things in the peripherals’ documentation. Remember to terminate the last internal device.

EVICES

If you are connecting external SCSI devices, make sure that (a) you have enough external SCSI cables to accomodate all of your devices (the Adapter does not come with any external cables), (b) the total length of the cables is not too great, and (c) the cables have the appropriate characteristics (see Sections 3.3 and 4.2.1). If your external devices have micro D68 connectors like the Adapter itself does, you can use our External Ultra2 LVD SCSI Cable (product code EVMS25).

1. Prepare each external SCSI peripheral for installation: configure the device’s SCSI ID and termination (terminate the last external device attached to the bus). For instructions, see the device’s documentation as well as Sections 3.2 through 3.4.

2. Plug the connector at one end of the first external SCSI cable into the Adapter’s external SCSI connector. These connectors will be keyed for proper cable insertion.

3. Plug the connector at the other end of the external SCSI cable into one of the SCSI connectors on the first external SCSI peripheral, following the instructions for doing this in the peripheral’s documentation.

4. To connect other external SCSI devices, use additional external SCSI cables to daisychain each device to the previous device until all external SCSI devices have been connected, as described in the peripherals’ documentation and as shown in Figure 4-5 on the next page (refer to the peripherals’ documentation for more information). Remember to terminate the last external device.

5. Reconnect all external devices to the PC and plug the PC back in.
