LSIU40SE Dual Channel PCI to Ultra SCSI Host Adapter 1-1
Chapter 1
Using the LSIU40SE
This chapter describes the LSIU40SE Dual Channel PCI to Ultra SCSI
Host Adapter interface to PCI computer systems and includes these
topics:
•Section 1.1, “General Description,” page 1-1
•Section 1.2, “Features,” page 1-2
•Section 1.3, “Interface Descriptions,” page 1-3
1.1 General Description
The LSI Logic LSIU40SE provides a SCSI-3, Ultra SCSI interface to PCI
computer systems. Installing this adapter in your PCI system allows
connection of SCSI devices over a SCSI bus.
The dual channel LSIU40SE is a 16-bit, Single-Ended (SE), SCSI
solution for your computer, using only one PCI slot. This board can
support legacy Fast SCSI devices, and the newest Ultra SCSI devices.
It is also backwards compatible with the existing LSI8751SP host adapter
but with a different external connector.
The Storage Device Management System (SDMS™) software operates
the board. The design of the board does not prevent other software from
being written and used with it. BIOS support for this host adapter is
incorporated on the board in an 8 X 64K Flash BIOS.
This guide, along with the PCI Storage Device Management System
SDMS 4.0 User’s Guide, contains product information and installation
instructions to help you gain the full benefits of the LSIU40SE.

Interface Descriptions 1-3
1.3 Interface Descriptions
This section provides a more detailed explanation about the PCI
Interface, the SCSI Interface, and Ultra SCSI.
1.3.1 The PCI Interface
PCI is a high-speed standard local bus for interfacing a number of I/O
components to the processor and memory subsystems in a high end PC.
The PCI functionality for the LSIU40SE is contained within the
LSI53C876 PCI to Ultra SCSI I/O Processor chip. The LSI53C876
connects directly to the PCI bus and generates timing protocol in
compliance with the PCI Local Bus Specification Revision 2.1 standard.
The PCI interface operates as a 32-bit DMA bus master. The connection
is made through edge connector J1 (see Figure 2.1). The signal
definitions and pin numbers conform to the PCI Local Bus Specification
Revision 2.1 standard. The LSIU40SE conforms to the PCI universal
signaling environment for a 5 V or 3.3 V PCI bus.
1.3.2 The SCSI Interface
The SCSI functionality for the LSIU40SE is contained within the
LSI53C876. The LSI53C876 connects directly to the two SCSI buses and
generates timing and protocol in compliance with the SCSI standard.
The SCSI interfaces on the LSIU40SE operate as 16-bit, synchronous or
asynchronous, SE bus, and support Ultra SCSI protocols and 16-bit
arbitration. Each interface is made through two of the connectors J2, J3,
and J4 (for Channel A), or J6, J7, and J8 (for Channel B). Connectors
J2 and J6 are 68-pin high density right-angle receptacles. Connectors J3
and J7 are shielded 68-pin VHDCI 0.8 mm right-angle receptacles that
protrude through the back panel bracket. Connectors J4 and J8 are
50-pin low density vertical shrouded pin headers. See Figure 2.1 for the
location of these connectors.
SE SCSI active termination is provided on the LSIU40SE. Termination is
automatically enabled when only one of the connectors J2, J3, and, J4
(or J6, J7, and, J8) is used, or when an 8-bit device is connected to the
16-bit J3 or J7 connectors. In the latter case, only the upper 8 data bits
are automatically terminated. The LSIU40SE supplies SCSI bus

1-4 Using the LSIU40SE
TERMPWR through a blocking diode and a self-resetting 1.5 A short
circuit protection device. The on-board LED lights when TERMPWR is
shorted. Separate switches for each channel allow user override of
termination.
A 40 MHz oscillator is installed on the LSIU40SE to provide the clock
frequency to the LSI53C876 that is necessary to support Wide Ultra
SCSI transfers of up to 40 Mbytes/s.
1.3.3 Ultra SCSI
The LSIU40SE fully supports Ultra SCSI as well as Fast SCSI
simultaneously. Ultra SCSI is an extension of the SCSI-3 family of
standards that expands the bandwidth of the SCSI bus, allowing faster
synchronous data transfers.
Special SCSI cables are specified for operation with Ultra SCSI devices.
You must consider the total number of devices and the length of the SCSI
bus when setting up your system. See Chapter 2, “Installing the
LSIU40SE,” for a more detailed explanation of SCSI bus connections.

LSIU40SE Dual Channel PCI to Ultra SCSI Host Adapter 2-1
Chapter 2
Installing the LSIU40SE
This chapter provides instructions on how to install the LSIU40SE 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 2-28
2.1 Quick Installation Procedure
This section is provided for the experienced computer user with prior
host adapter installation and SCSI bus setup experience. If you prefer a
more detailed guidance in installing the LSIU40SE, please follow the
instructions in Section 2.2, “Detailed Installation Procedure.”
For safe and proper installation, check the user’s manual supplied with
your computer and perform the following steps.
Step 1. Ground yourself before removing this host adapter board.
Remove the LSIU40SE from the packing and check that it is not
damaged. An example of this host adapter board is shown in
Figure 2.1.
Step 2. Switch off and unplug the system.
Step 3. Remove the cabinet cover on your computer to access the PCI
slots. Refer to the user’s manual for your computer.
Caution: Ground yourself by touching a 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.

2-2 Installing the LSIU40SE
Step 4. Locate the slots for PCI plug-in board installation. The
LSIU40SE requires a PCI slot that 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.
Step 6. Carefully insert edge connector J1 (see Figure 2.1) of the host
adapter into the PCI slot. Make sure the edge connector is
properly aligned before pressing the board into place.
Note: You may notice that the components on a PCI host adapter
face the opposite way from non-PCI adapter boards you
have in your system. This is correct, and the board is keyed
to go in only one way.
Step 7. The bracket around the connectors J3 and J7 (see Figure 2.1)
should fit where the blank bracket panel was removed. Secure
the bracket with the bracket screw before making the internal
and external SCSI bus connections.
Step 8. If you are connecting any internal SCSI devices, plug a 68-pin
connector on the end of the internal SCSI ribbon cable into
connector J2 or J6 for Wide SCSI, or a 50-pin connector into
connector J4 or J8 for normal SCSI (see Figure 2.1). Make
certain to match pin 1 on both connectors.
Step 9. Connect your computer’s LED cable if desired. This is designed
to drive the front panel LED found on most PC cabinets to
indicate activity on the SCSI bus.
Step 10. Replace the cabinet cover as described in the user’s manual for
your computer.
Step 11. Make all external SCSI bus connections. Finally, refer to the
PCI Storage Device Management System SDMS 4.0 User’s
Guide (or the guide for the software that you will use) to load
the driver software for your particular operating system.
Remember: The SCSI bus requires proper termination, and no
duplicate SCSI IDs.
