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 LSI22910 provides two SCSI-3, Ultra2 SCSI interfaces to
PCI computer systems that require BIOS support on the add-in SCSI
adapter. Installing this adapter in your PCI system allows connection of
SCSI devices over a SCSI bus.
The LSI22910 is a 16-bit Low Voltage Differential (LVD) and Single-
Ended (SE) SCSI solution for your computer. This board can support
legacy Fast SCSI devices, Ultra SCSI devices, and the newest Ultra2
SCSI devices.
The LSI Logic Storage Device Management System (SDMS™) software
operates the board. The design of the board does not prevent other SCSI
software from being used with it. BIOS support for this host adapter is
incorporated on the board in a 128K Flash device.
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 LSI22910.

1.3 Interface Descriptions
This section provides a more detailed explanation about the PCI
Interface, the SCSI Interface, the SCSI Activity LED Interface, and Wide
Ultra2 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 subsystem in a high end PC.
The PCI functionality for the LSI22910 is contained within the LSI Logic
LSI53C896 PCI to SCSI I/O Processor chip. The LSI53C896 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 or 64-bit DMA bus master. The
connection is made through edge connector J1 (see Figure 2.1 on
page 2-5). The signal definitions and pin numbers conform to the PCI
Local Bus Specification Revision 2.1 standard. The LSI22910 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 LSI22910 is contained within the LSI Logic
LSI53C896. The LSI53C896 connects directly to the SCSI buses for SE
or LVD SCSI applications and generates timing and protocol in
compliance with the SCSI standard. Each SCSI interface operates at a
burst transfer rate of up to 40 Mbytes/s for wide SE transfers, and up to
80 Mbytes/s for wide LVD SCSI transfers.

1-4 Using the LSI22910
The SCSI interfaces on the LSI22910 operate as two 16-bit, synchronous
or asynchronous, SE or LVD, and support Ultra2 SCSI protocols and
16-bit arbitration. The interface is made through connectors J2 and J5 for
Channel A and J3 and J4 for Channel B. Connectors J2 and J3 are
68-pin VHDCI right-angle receptacles that protrude throughout the
ISA/EISA bracket. Connectors J4 and J5 are 68-pin high density latching
right-angle receptacles for internal SCSI connections. See Figure 2.1 on
page 2-5 for the location of these connectors.
The LSI22910 provides autosensing, dual mode SE/LVD SCSI
termination. Termination is normally enabled. When a SCSI device is
sensed to be connected to both internal and external connectors,
termination for that channel is automatically disabled.
The LSI22910 supplies SCSI bus TERMPWR through a blocking diode
and self-resetting 1.5 A short circuit protection device. An on-board LED
lights up when TERMPWR is shorted and turns off.
A 40 MHz oscillator is installed on the LSI22910 board to provide the
clock frequency to the LSI53C896 that is necessary to support Wide
Ultra2 SCSI transfers of up to 80 Mbytes/s.
1.3.3 SCSI Activity LED Interface
The LSI22910 LED interface is a four-wire arrangement that allows you
to connect an LED harness to the board. The connector on the LSI22910
is J6 for both channels. See Table A.5 on page A-9 for the signal name
and pin numbers for this LED interface.
Four individual LEDs per channel are on the LSI22910 so you can
decode the operating state of the board. The four activity LEDs are:
•SCSI Activity – Green LED, right edge of board
•TERMPWR SHORTED – Yellow LED, right edge of board
•LVD Mode – Green LED, right edge of board in LVD Mode
•TERMPWR GOOD – Green LED, right edge of board when
TERMPWR is above + 3 V

Interface Descriptions 1-5
1.3.4 Wide Ultra2 SCSI
The LSI22910 fully supports Wide Ultra2 SCSI. This interface is an
extension of the SCSI-3 family of standards that expands the bandwidth
of the SCSI bus to allow faster synchronous data transfers, up to
80 Mbytes/s. Wide Ultra2 SCSI provides a doubling of the data rate over
the Ultra2 SCSI interface, while it increases cable lengths and allows a
larger number of devices on the cable than Ultra2 SCSI interfaces.
Special SCSI cables are specified for operation with Wide Ultra and
Ultra2 SCSI devices. You must consider the total number of devices and
the length of your SCSI bus when setting up your system. See Chapter 2,
“Installing the LSI22910,” for a more detailed explanation of SCSI bus
connections.
When you purchased the LSI22910 kit, the cable provided in the kit is
matched for a Fast/Ultra/Ultra2 SE or LVD operation. This cable also has
built-in LVD termination since most Ultra2 hard disk drives are not made
with on-board LVD termination. Table 1.1 provides an overview of
standard SCSI cable specifications.

all devices on the bus support LVD, then 12-meter operation is
possible at this speed. However, if any device on the bus is SE only,
then the entire bus switches to SE mode, and the distances in the
SE column apply.

Chapter 2
Installing the LSI22910
This chapter provides instructions on how to install the LSI22910 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 2-24
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 for installing the LSI22910, 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 LSI22910 from the packing and check that it is not
damaged. An example of this host adapter board is shown in
Figure 2.1 on page 2-5.
Step 2. Switch off and unplug the system.
Step 3. Remove the cabinet cover on your computer to access the PCI
slots.
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 LSI22910
Step 4. Locate the slots for PCI plug-in board installation. A 32-bit slot
may be used, but full performance requires a 64-bit slot. Refer
to the user’s manual supplied with your computer to confirm the
location of the PCI slots. The LSI22910 requires a PCI slot that
allows bus master operation. See Figure 2.2.
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 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 non-PCI 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 J2 and J3 should fit where
the blank panel was removed. Secure it with the bracket screw
before making 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 the internal SCSI ribbon cable into the
connector J4 or J5 (see Figure 2.1).Makecertaintomatch
pin 1 on both connectors. Chain your internal devices on this
cable.
Step 9. Connect the 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. See Table A.5 on page A-9 for the signal
name and pin numbers for this LED interface.
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.
