viii IBM PCI Ultra160 SCSI Adapter: User’s Guide

Part 1: Quick installation guide

The IBM®PCI Ultra160 SCSI Adapter is designed to attach a small computer system interface (SCSI) to a computer that has an available peripheral component interconnect (PCI) expansion slot. After the adapter is installed, SCSI devices can be attached to the external SCSI connector. In addition to this User’s Guide, the option package contains:

v The 29160LP SCSI Adapter v One 68-pin, internal SCSI cable for connecting five 16-bit internal Wide

devices

v One 4-pin internal LED cable v The option CD, which contains the EZ-SCSI and 7800 Family Manager Set

device driver and utility packages

v The IBM Safety Information Book

This section contains abbreviated installation instructions. If you are familiar with SCSI products and are experienced in installing options, use these instructions. For a description of the SCSI adapter and more detailed information about how to install it see “Part 2: Installation and user’s guide” on page 2-1. To install the SCSI adapter, do the following:

1. Set a unique SCSI ID for each device you are connecting to the SCSI chain.

The adapter supports SCSI IDs from 0 to 15. The SCSI ID of the SCSI adapter is 7.

2. Turn off all attached devices; then turn off your computer. Unplug the

power cords and all attached devices. Remove the cover from your computer. For instructions on how to remove the computer cover, refer to the documentation that comes with your computer.

3. Before opening the static-protective bag containing the SCSI adapter, touch

the bag to an unpainted metal surface on your computer for at least two seconds.

4. Remove the adapter from the static-protective bag. If you must put the

adapter down, place it on the static-protective bag.

The following is an illustration of the SCSI adapter:

168-pin Internal LVD/SE Connector 468-pin External VHDCI Connector 2External LED connector 5mounting screws 3PCI bus card-edge connector 6bracket

5. Locate an available 32-bit or 64-bit PCI expansion slot. These slots are

shorter than ISA or EISA slots.

6. If you have a newer, lower-profile computer, you will need to use the

smaller mounting bracket that comes with the adapter. To install it, reference the illustration and do the following:

a. Remove the mounting screws that attach the bracket to the adapter. b. Remove the standard bracket. c. Position the low-profile bracket on the bracket aligning the screw holes

in the bracket with the holes in the PCI adapter.

d. Insert the two screws and carefully tighten the screws. Do not

overtighten.

7. Remove the bracket screw and the metal expansion slot cover.

8. Insert the connector of the adapter, (P1 in the above illustration) into the

PCI connector.

9. Press the SCSI adapter into place and secure it with the bracket screw.

10. The internal SCSI cable included in this option package has an adaptive

terminator at the end. This terminator serves as the termination device for all SCSI devices that are attached to the cable. Remove or disable termination from all other devices on the SCSI cable.

11. If needed, set the SCSI adapter termination. Termination of the SCSI

adapter is controlled by software commands using the SCSISelect utility program. The initial termination setting for the SCSI adapter is Automatic. With this setting, the adapter detects the bus cables attached and sets proper termination settings. If you want to manually set the termination for the SCSI adapter, see “Appendix B. Using SCSISelect” on page B-1.

1-2 IBM PCI Ultra160 SCSI Adapter: User’s Guide

12. Mount and connect each internal SCSI device in your computer. Connect

the 68-pin cable into the connector for 16-bit Wide SCSI devices (J1 in the illustration of the adapter).

13. Connect the internal devices to available connectors starting at the end of

the SCSI cable farthest from the adapter and closest to the terminator to ensure best signal quality. For each device connect pin-1 on each cable connector to pin-1 on each device, otherwise your SCSI devices will not work correctly.

14. You can connect a light-emitting diode (LED) to indicate SCSI hard disk

drive activity. Unplug the LED cable from the connector on the computer system board. Connect the LED cable connector to the external LED connector on the SCSI adapter (J3 in the illustration of the adapter).

15. Connect the power cable for each device to the internal power source, as

needed. Replace and secure the cover on your computer.

16. If you have external SCSI devices, connect your external SCSI cable (not

provided with this option) to the external connector on the SCSI adapter (J5 in the illustration of the adapter) and then connect your external devices.

17. Reconnect the power cord and other cables. Turn on all attached devices;

then turn on your computer. If your computer does not recognize the SCSI adapter, start your configuration program and review and set the configuration options.

18. The initial SCSISelect adapter settings work for most computers with PCI

expansion slots. If you need more information about changing the initial settings, see “Appendix B. Using SCSISelect” on page B-1.

19. Install the device driver and utility software.

The Microsoft

Windows®95, Windows 98, Microsoft Windows

Workstation, Novell NetWare, IBM OS/2®, SCO UNIX®, and UnixWare operating systems might already contain device drivers for your SCSI adapter. If this is the case, your operating system will recognize the device after installation and will use the appropriate device drivers. If your operating system does not recognize the SCSI adapter after installation, you will need to use the option CD to install the appropriate device drivers.

Device drivers for the adapter are included in the EZ-SCSI software package which contains device drivers for the following operating systems:

v Windows 95, Windows 98, Microsoft Windows Millennium (Me) v Windows NT 4.0

1-4 IBM PCI Ultra160 SCSI Adapter: User’s Guide

Part 2: Installation and user’s guide

Product description

The IBM PCI Ultra160 SCSI Adapter is designed to attach SCSI devices to a computer that has an available peripheral component interconnect (PCI) expansion slot. You can connect up to 15 SCSI devices to the adapter (disk drives, CD drives, scanners, and other devices) in a daisy-chain fashion. The SCSI adapter can be used in place of, or together with, a standard IDE adapter.

If you need to configure the adapter, use the SCSISelect utility program that is built-in to the SCSI adapter. SCSISelect enables you to change the adapter settings without opening the computer or handling the adapter.

In addition to the User’s Guide, this option package contains the following:

v The SCSI 29160LP Adapter v One 68-pin, internal SCSI cable for connecting five 16-bit Wide SCSI devices v LED cable v The option CD which contains the EZ-SCSI and 7800 Family Manager Set

device driver and utility packages

v The IBM Safety Information Book

Before you begin

The adapter is sensitive to static electricity; even a mild discharge can destroy one or more of its components. Keep the adapter in its static-protective package until you are ready to install it in your computer. Before you handle the adapter, always discharge any charge that might have built up in you by touching an unpainted surface on your computer.

System requirements

In addition to this option package, you need the following:

v Personal computer that supports PCI Revision 2.0. v An available 32-bit or 64-bit PCI expansion slot that is capable of bus

mastering. Some PCI-bus computers have both bus-mastering and non-bus mastering slots. Read your computer documentation to determine the type of PCI slots your computer has.

v Low voltage differential (LVD) or single-ended SCSI devices.

You might also need one or more of the following: v A 68-pin external SCSI cable for connecting each external 16-bit Wide SCSI

device.

v A termination device for external SCSI devices (if needed to terminate

external SCSI chain). To provide reliable SCSI device operation, use only an active terminator compatible with the type of devices you are using. For instance, if you are using all LVD SCSI devices, use an LVD termination device. If you have any devices on the external SCSI chain that are LVD devices, you can use both LVD and non-LVD termination devices.

Choosing SCSI cables

Round external SCSI cables vary widely in quality and electrical characteristics. Be sure that external SCSI cables meet LVD SCSI standards. Do not use cables shorter than 30 cm (11.8 in.) between any two SCSI devices.

To ensure reliable operation, the total length of the SCSI bus, including both the internal and external cabling, is an important factor. Follow these guidelines for total SCSI cable length:

v If any Fast SCSI devices are connected to the SCSI adapter, the total length

of all cables must not exceed 3 meters (9.8 ft.).

v If no Fast SCSI devices are connected, the total length of all cables must not

exceed 6 meters (19.7 ft.).

v If only LVD SCSI devices are connected to the SCSI adapter, the total length

of all cables must not exceed 12 meters (39.4 ft.).

Installing the adapter

Follow these steps to install the SCSI adapter.

Step 1. Assigning SCSI IDs

Each device attached to the SCSI adapter, as well as the adapter itself, must have a unique SCSI ID number from 0 to 15. The SCSI ID serves two purposes: it uniquely defines each SCSI device on the SCSI bus, and it determines the device priority for service on the SCSI bus.

The adapter supports the SCSI configured automatically (SCAM) protocol which assigns SCSI IDs dynamically and resolves SCSI ID conflicts automatically at startup. Most SCSI devices currently in use, however, do not support SCAM. The SCSI IDs on these devices must be set manually. Consider the following when assigning a SCSI ID:

v Determine the SCSI ID assignments for devices currently installed. You

might be able to use the existing ID assignments. To determine existing SCSI ID assignments, use one of the following.

– For most IBM computers, press the F1 key during start up after the

memory check completes.

– Use the SCSI utility programs which came with your SCSI devices. – Inspect the installed SCSI devices to see how the IDs are set.

2-2 IBM PCI Ultra160 SCSI Adapter: User’s Guide

v ID 7 is the highest priority ID on the SCSI bus. Make sure ID 7 is assigned

to the SCSI adapter. Do not use the SCSISelect utility program to change the ID assignment of the SCSI adapter. The priority of the other IDs in descending priority order are 6 to 0 and 15 to 8.

v Assign higher priority SCSI ID numbers to the devices that are most often

used or are faster than other devices in the SCSI chain. (The SCSI ID assigned to a device is not related to the order in which the devices are attached to the SCSI adapter.)

v If you start up your computer from a SCSI device, assign SCSI ID 0 to the

startup drive. ID 0 is the SCSISelect initial setting. (If both SCSI and IDE disk drives will be installed, you cannot start up your computer from a SCSI device. In this case, the IDE disk drive is always the startup device.)

v Change the ID settings according to ID assignments you have chosen. Refer

to the documentation that comes with your SCSI devices for information on how to change the SCSI ID. One way to remember the SCSI ID for each device is to label the device. When putting the label on a hard disk drive, do not press down on the top of the drive because the pressure might damage it.

You can also use the following table in your planning by writing down the SCSI ID you assign to each device. The SCSI IDs are listed in decreasing priority order.

SCSI ID Device

7 SCSI Adapter 6 5 4 3 2 1 0 15 14 13 12 11 10 9 8

Part 2: Installation and user’s guide 2-3

Note that if you install more than one SCSI adapter in your computer, each adapter has a separate SCSI bus, and you can use each SCSI ID once on each bus.

Step 2. Opening your computer

1. Turn off all attached devices; then turn off your computer.

2. Unplug the power cords for your computer and all attached devices; then

open your computer. For specific information on opening your computer, refer to the documentation that comes with your computer.

Step 3. Unpacking the SCSI adapter

1. Before opening the static-protective bag containing the SCSI adapter, touch

the bag to an unpainted metal surface on your computer for at least two seconds.

2. Remove the adapter from the static-protective bag. If you must put the

adapter down, place it on top of the static-protective bag.

3. Inspect the adapter before you install it in your computer for any physical

damage. The following illustration identifies the adapter components.

168-pin Internal LVD/SE Connector 468-pin External VHDCI Connector 2External LED connector 5mounting screws 3PCI bus card-edge connector 6bracket

Step 4. Inserting the adapter into the PCI slot

1. Locate an available 32-bit or 64-bit PCI expansion slot. These slots are

shorter than ISA or EISA slots as shown in the illustration. The PCI bus

2-4 IBM PCI Ultra160 SCSI Adapter: User’s Guide

connectors (inside the computer) are colored white.

2. Remove the bracket screw and metal expansion slot cover.

3. If you have a newer, lower-profile computer, you will need to use the

smaller mounting bracket that comes with the adapter. To install it do the following:

a. Remove the mounting screws that attach the bracket to the adapter. b. Remove the standard bracket. c. Position the low-profile bracket on the bracket, aligning the screw holes

in the bracket with the holes in the PCI adapter.

d. Insert the two screws and carefully tighten the screws. Do not

overtighten.

4. Insert the card-edge connector, P1, into the empty PCI bus connector. Press

the SCSI adapter into place and secure it with the bracket screw.

Step 5. Terminating the SCSI bus

SCSI devices connect in series to one another on a SCSI bus in a daisy-chain fashion. For the devices to work properly, SCSI termination is required at both ends. All devices that are between the ends of a SCSI chain must have their termination devices removed or disabled.

The internal SCSI cable that comes with this option has an LVD SCSI termination device at the end of the cable farthest from the adapter. All SCSI devices that are connected to the internal cable between the SCSI adapter and the termination device at the end of the cable must have termination devices removed or disabled. Any terminators on internal SCSI devices must be

Part 2: Installation and user’s guide 2-5

removed also. When no external SCSI devices are attached to the bus, the internal cable is terminated at one end by the SCSI adapter itself, and at the other by the termination device on the internal cable.

The following are possible SCSI termination configurations. If the SCSI configuration consists of one cable, terminate the last device 1 on the cable. Remove termination from other devices on the cable.

If the SCSI bus consists of one internal SCSI cable and one external SCSI cable, terminate the last device 2 on the external SCSI cable and the last device 3 on the internal SCSI cable. Remove termination from the other devices on each cable.

Step 6. Terminating the SCSI adapter

Termination on the SCSI adapter is controlled by software commands using the SCSISelect. The initial termination setting is Automatic.
