2.1 Installing your Ultra160 SCSI Host Adapter
This section provides detailed instructions for installing your host adapter
board and connecting it to your SCSI peripherals. The following
illustrations depict the LSI21003 PCI to Dual Channel Ultra160 SCSI
Host Adapter. However, these illustrations are applicable to all boards.
2.1.1 Selecting a PCI Slot
Step 1. Ground yourself before removing the host adapter board from
its package to discharge static electricity.
Caution: Ground yourself by touching a grounded 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 2. Remove your Ultra160 SCSI host adapter from its packing and
verify it is not damaged.
Step 3. Turn off and unplug your computer and peripherals.
Ultra160 SCSI to PCI Host Adapters 2-1
Step 4. Remove the cabinet cover on your computer to access the PCI
slots.
Step 5. Locate the PCI slots on your computer.
Use a 32-bit slot for 32-bit host adapters and a 64-bit slot for
64-bit host adapters. You may insert a 64-bit host adapter into
a 32-bit slot if not 64-bit slots are available. Refer to the user’s
manual supplied with your computer to confirm the location of
the PCI slots.
2.1.2 Inserting the Host Adapter
Perform the following steps to install your Ultra160 SCSI Host Adapter 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.
Step 3. Make sure the edge connector is properly aligned before
pressing the board into place. The bracket around connector J3
should fit where the blank bracket panel was removed.
Figure 2.1 illustrates the hardware connections. All the
connectors in this example pertain to the LSI21003. Other
Ultra160 SCSI host adapters will have different connector
labels depending on the board design. Refer to Chapter 3,
“Ultra160 SCSI to PCI Host Adapter Characteristics,” for more
information.

2.2.1 Making Internal Wide SCSI Bus Connections
This section provides step-by-step instructions for making internal SCSI
bus connections. These steps refer to connectors that are specific to the
LSI21003. Internal and external connectors can be 50-pin or 68-pin.
Refer to Section 3.3.1, “Internal SCSI Cables,” page 3-10 for examples
of internal cables.
If you have only external connections, skip to Section 2.2.2, “Making
External SCSI Bus Connections,” otherwise follow these steps:
2-4 Detailed Host Adapter Installation
Step 1. Plug the 68-pin connector on the SCSI ribbon cable into the
internal connector on the host adapter board. Figure 2.3
illustrates how to make this connection.

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. Figure 2.4 illustrates the chaining of internal SCSI
devices.
If you have more than one internal SCSI device, you must have
a cable with at least as many connectors as you have devices.
Note: Daisy chaining devices represent an arrangement of
devices connected in a series. Any signal transmitted to the
devices goes to the first device, from the first to the second,
and so on. Termination occurs on the last internal SCSI
device.
See Section 2.3, “Terminating the SCSI Bus,” for more
information on SCSI bus termination.

2.2.2 Making External SCSI Bus Connections
This section provides step-by-step instructions for making external SCSI
bus connections. Refer to Section 3.3.2, “External SCSI Cables and
Connectors,” page 3-11 for examples of external cables.
Step 1. Plug the 50-pin connector on one end of a shielded external
high density cable into the appropriate connector.
This connector is exposed on the back panel of your computer.
Step 2. Plug the 50-pin connector on the other end of the shielded
external SCSI cable into the SCSI connector on your external
SCSI device.

Figure 2.5 shows an example of an external SCSI connection
to a single external SCSI device. If you have the correct cable,
it matches the external connector. Termination occurs on the
last SCSI device. See Section 2.3, “Terminating the SCSI Bus,”
for more information about SCSI bus termination.

2.3 Terminating the SCSI Bus
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. 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.
To utilize Ultra160 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 speed, limiting bus performance to Ultra SCSI. LVD
peripheral devices are normally terminated with external terminators, but
are sometimes set with jumpers or with a switch on the peripheral.
2-8 Detailed Host Adapter Installation
The Ultra160 SCSI host adapters automatically control SCSI bus
termination for various bus configurations.
In one case, you may disable termination by using BIOS software control
to change the BIOS termination from Automatic to Off.
In another case where jumpers are provided on the board, you would
locate the shunts on the board for autotermination override. 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. Figure 2.7 illustrates how the shunt controls
autotermination.
Figure 2.7 Autotermination Shunt
Autotermination enabled (no jumper installed)
Termination disabled (jumper installed)
2.3.1 Internal and External SCSI Terminations
If you are making internal SCSI device connections to your host adapter,
you must terminate the last internal device on the SCSI bus. If you are
making external SCSI device connections to your host adapter, you must
terminate the last external 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.
2.3.2 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.
Normally, you do not change the host adapter SCSI ID setting. If you
wish to do so, refer to the PCI Storage Device Management System
SDMS 4.0 User’s Guide, which explains how to set your host adapter ID
using the SCSI BIOS Configuration Utility.
Terminating the SCSI Bus 2-9
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. To set your SCSI IDs, follow these steps:
Step 1. Determine the SCSI ID of each device on the SCSI bus.
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 provides a place to keep this record.

SCAM SCSI Configured AutoMatically. A method to automatically allocate SCSI
IDs using software when SCAM compliant SCSI devices are attached.
SCSI Small Computer System Interface. A specification for a high-performance
peripheral bus and command set. The original standard is referred to as
SCSI-1.
SCSI Bus A host adapter and one or more SCSI peripherals connected by cables
in a linear chain configuration. The host adapter may exist anywhere on
the chain, allowing connection of both internal and external SCSI
devices. A system may have more than one SCSI bus by using multiple
host adapters.
SCSI Device Any device that conforms to the SCSI standard and is attached to the
SCSI bus by a SCSI cable. This includes SCSI host adapters and SCSI
peripherals.
SCSI ID A way to uniquely identify each SCSI device on the SCSI bus. Each
SCSI bus has eight available SCSI IDs numbered 0 through 7 (or 0
