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 LSIU40HVD is contained within the
LSI53C876 PCI to SCSI I/O Processor chip. The LSI53C876 chip
connects directly to the PCI bus and generates timing protocol in
compliance with the PCI specification.
The PCI interface operates as a 32-bit DMA bus master. The connection
is made through the 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 LSIU40HVD 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 LSIU40HVD is contained within the LSI
Logic LSI53C876. The LSI53C876 chip connects directly to the two SCSI
buses and generates timing and protocol in compliance with the SCSI
standard.
The SCSI interface on the LSIU40HVD operates as a 16-bit,
synchronous or asynchronous, differential bus, and supports Ultra SCSI
protocols and 16-bit arbitration. Each interface is made through the
connectors J2 and J3 (for Channel A), or J5 and J6 (for Channel B).
Connectors J2 and J5 are 68-pin high-density, right-angle receptacles.
Interface Descriptions 1-3
Connectors J3 and J6 are shielded 68-pin VHDCI right-angle receptacles
that protrude through the back panel bracket. See Figure 2.1 for the
location of these connectors.
Differential SCSI active termination is provided on the LSIU40HVD.
Termination is automatically enabled when only one of the connectors J2
and J3 (or J5 and J6) is used, or when an 8-bit device is connected to
the 16-bit J3 or J6 connectors. The LSIU40HVD supplies SCSI bus
TERMPWR (termination power) through a blocking diode and a
self-resetting 1.5 A short circuit protection device. An on-board LED
lights when TERMPWR is off. Separate jumpers for each channel allow
user override of termination.
A 40 MHz oscillator is installed on the LSIU40HVD to provide the clock
frequency to the LSI53C876 chip that is necessary to support Wide Ultra
SCSI transfers of up to 40 Mbytes/s.
1.3.3 Ultra SCSI
The LSIU40HVD has full support for Ultra SCSI as well as supporting
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, and you must consider the total
number of devices and the length of your SCSI bus when setting up your
system. See the section on connecting your SCSI peripherals in
Chapter 2, "Installing the LSIU40HVD," for a more detailed explanation
of SCSI bus connections.

Chapter 2
Installing the
LSIU40HVD
This chapter provides instructions on how to install the LSIU40HVD 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, “Setting Interrupts,” page 2-22
• Section 2.4, “Completing the Installation,” page 2-23
2.1 Quick Installation Procedure
This section provides quick setup instructions for the experienced
computer user with prior host adapter installation and SCSI bus setup
experience. If you prefer more detailed guidance for installing the
LSIU40HVD, 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 the host adapter board.
Remove the LSIU40HVD from the packing and check that it is
not damaged. An example of this 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.
LSIU40HVD PCI to Dual Channel SCSI Host Adapter 2-1
Caution: Ground yourself by touching a metal surface before han-
dling 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 4. Locate the slots for PCI plug-in board installation.
Refer to the user’s manual for your computer to confirm the
location of the PCI slots. The LSIU40HVD requires a PCI slot
which allows bus master operation. See Figure 2.2.
Step 5. Remove the blank panel on the back of the computer aligned
with the PCI slot you intend to use. Save the bracket screw.
Step 6. Carefully insert the 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. See
the example shown in Figure 2.2.
Note: You may notice that the components on a PCI host adapter
face the opposite way from those on other 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 J6 (see Figure 2.1)
should fit where the blank panel was removed. Secure it with
the bracket screw beforemaking the internal and external SCSI
bus connections (see Figure 2.2).
Step 8. If you are connecting any internal SCSI devices, plug a 68-pin
connector on the end of an internal SCSI ribbon cable into
connector J2 or J5 (see Figure 2.1). Make certain to match pin
one on both connectors. Chain the internal devices on this
cable.
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.
Remember: The SCSI bus requires proper termination, and no
duplicate SCSI IDs.
