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.

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

Interface Descriptions

1-3

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.

Using the LSIU40SE

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.

LSIU40SE Dual Channel PCI to Ultra SCSI Host Adapter

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.

Step 8. The bracket around the connectors J3 and J7 (see Figure 2.1)

should ﬁt where you removed the blank panel. Secure it with

the bracket screw (see Figure 2.2) before making the internal

and external SCSI bus connections.

2.2.3 Connecting the SCSI Peripherals

SCSI bus connections to the LSIU40SE are made with an unshielded,

68 or 50-conductor ribbon cable (see Figure 2.3). One side of this cable

is marked with a color to indicate the pin-1 side. Sometimes the

connectors on this cable are keyed to ensure proper pin-1 connection.

2-6

Installing the LSIU40SE

All external SCSI bus connections to the LSIU40SE are made with

shielded, 68-conductor cables (see Figure 2.3). The connectors on this

cable are always keyed to ensure proper pin-1 connection.

Important: You can connect up to 16 SCSI and Fast SCSI devices,

including the host adapter board, on a SE SCSI bus only if

they are at least .3 m apart on a 6-meter cable. For Ultra

SCSI, you can connect up to eight devices, including the

host adapter board, on a SE Ultra SCSI bus only if they are

evenly spaced on a 1.5-meter Ultra SCSI cable (0.19 m

between devices). You can connect up to four devices if

they are evenly spaced on a 3-meter Ultra SCSI cable

(0.75 m between devices). Your SE SCSI bus should not

exceed 3 meters (total internal and external cable lengths),

Detailed Installation Procedure

2-7

even with fewer than four devices. The LSIU40SE

autotermination scheme is designed to operate properly

when plugging the end connector of the SCSI cables into

the LSIU40SE SCSI connectors.

If you connect the LSIU40SE in the middle of the bus, you

will incur improper termination since the switches are not

assigned on that bus correctly. Refer to Section 2.2.10.1,

“Channel Switches,” for more information.

2-8

Installing the LSIU40SE

2.2.4 Making Internal SCSI Bus Connections

This section provides step-by-step instructions about making internal

SCSI bus connections.

Step 1. If you are connecting an internal Wide SCSI device, plug the

68-pin connector on one end of a wide internal SCSI ribbon

cable into the connector J2 or J6 (see Figure 2.4).

Installing the LSIU40SE

Step 3. Plug the 68-pin or 50-pin connector on the other end of the

internal SCSI ribbon cable into the SCSI connector on the

internal SCSI device. An example of this connection is shown

in Figure 2.6. You must match pin 1 on all connections.

Figure 2.6 Internal SCSI Ribbon Cable to Internal SCSI Device

Connection

Detailed Installation Procedure

2-11

Step 4. Additional internal SCSI devices are plugged in by using an

internal SCSI ribbon cable with the required number of

connectors attached along its length as shown in Figure 2.7.

An example of this type of chained connection is shown in

Figure 2.8. Make sure to match pin 1 on all connections.

Figure 2.7 Connecting Additional Internal SCSI Devices

2-12

Figure 2.8 Multiple Internal SCSI Devices Chained Together

Detailed Installation Procedure

2-13

Step 5. It is also possible to use both internal connectors on a channel

if you do not attach any external devices to that channel. An

example of this conﬁguration is shown in Figure 2.9.

Figure 2.9 Using Both Internal Connectors on a Channel

Note:

When two connectors are already used on a channel, the

third connector cannot be used.

2-14

Installing the LSIU40SE

Step 6. Most PC cabinets are designed with a front panel LED

(sometimes already connected to an existing IDE drive). You

may connect this LED cable to the host adapter, as shown in

Figure 2.10. This causes the front panel LED to indicate activity

on the SCSI bus.

This connector is not keyed. The orientation of the LED cable

does not matter as long as all four pins are connected.

Figure 2.10 SCSI LED Connectors

Some LED cables have only two wires. In this case, place the connector

on one end or the other of J5 or J9. If the LED does not light during SCSI

bus activity from this host adapter, you may have to rotate the LED cable

180° on J5 or J9.

Detailed Installation Procedure

2-15

2.2.5 Making External SCSI Bus Connections

This section provides step-by-step instructions about making external

SCSI bus connections.

Step 1. To connect external SCSI devices to the LSIU40SE, plug the

68-pin connector on one end of a shielded external SCSI

VHDCI cable (see Figure 2.3) into the host adapter connector

J3 or J7 (see Figure 2.1).

This connector is now bracketed to the back panel of your

computer. Figure 2.11 shows how this connection is made.

Figure 2.11 External Cable to Host Adapter

2-16

Installing the LSIU40SE

Step 2. Plug the 68-pin connector on the other end of the shielded

external SCSI cable into the SCSI connector on the external

SCSI device. An example of this connection is shown in

Figure 2.12.

Step 3. To connect more than one external SCSI device to the host

adapter, you must chain them together with shielded external

SCSI cables. An example of these chained connections is

shown in Figure 2.13.

Figure 2.13 Multiple External SCSI Devices Chained Together

2-18

Installing the LSIU40SE

2.2.6 SCSI Bus Termination

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. Remember that the LSIU40SE is also on the SCSI

bus—its termination is automatically enabled when it is connected to the

end of the bus.

The peripheral device terminators are usually set with jumpers, resistor

modules, or with a switch on the peripheral. 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.

Caution:

The autoenable/disable sensing feature on the LSIU40SE

may enable termination erroneously if it is directly cabled to

another SCSI device or host adapter using the same

sensing method. This is dealt with by properly setting the

termination override switches U1 or U2 (see Figure 2.1).

The LSIU40SE senses SCSI devices by detecting the

ground signal on pin-22 of a 50-conductor internal SCSI

ribbon cable, or pin-50 of an internal or external

68-conductor SCSI cable. If you use an adapter to connect

8-bit devices externally with a 50-conductor SCSI cable, the

ground signal is detected on pin-34.

The LSIU40SE automatically covers SCSI bus termination for ﬁve

different bus conﬁgurations, depending on the use of the connectors on

the LSIU40SE (see Figure 2.1). The ﬁve bus conﬁgurations are:

•

Only for internal SCSI connections,

Only for external SCSI connections,

For both internal and external SCSI connections,

For connections to both internal connectors, and

For an internal connection to another LSIU40SE, or any connection

to a device using the same sensing method for automatic termination

as your LSIU40SE.

Detailed Installation Procedure

2-19

2.2.7 Internal SCSI Connections

If you have only internal SCSI device connections to the host adapter,

you must terminate the last internal device on the SCSI bus. You must

disable the termination on all other devices. Termination on the host

adapter is automatically enabled in this case.

Figure 2.14 shows an example of how termination is determined for this

SCSI bus conﬁguration.

Figure 2.14 Internal SCSI Device Termination

Installing the LSIU40SE

2.2.8 External SCSI Connections

If you have only external SCSI device connections to the host adapter,

you must terminate the last external device on the SCSI bus. You must

disable the termination on all other devices. Termination on the host

adapter is automatically enabled in this case.

Figure 2.15 shows an example of how termination is determined for this

SCSI bus conﬁguration.

2.2.10 Internal SCSI Connections for Both Internal Connectors

If you have internal SCSI device connections to both internal connectors

of a channel, you must terminate the internal devices on each end of the

SCSI bus. You must disable the termination on all other devices.

Termination on the host adapter is automatically disabled in this case.

Remember, you must not use the external connector for a channel if you

use both internal connectors for that channel.

Figure 2.17 shows an example of how termination is determined for this

SCSI bus conﬁguration. If you connect the LSIU40SE in the middle of

the bus, you will incur improper termination since the switches are not

assigned on that bus correctly.

If you have an internal connection to another LSIU40SE, or any

connection to a device that uses the same sensing method for automatic

termination as your LSIU40SE, you must properly set the termination

override switches U1 or U2 (see Figure 2.1).

Detailed Installation Procedure

2-23

2.2.10.1 Channel Switches

When connecting another LSIU40SE, you must turn on the switch for the

connector used on one or both of the boards. Please refer to Figure 2.18,

and the next two paragraphs, to determine the correct switch setting.

Four switches for each channel provide cable detection simulation and

forced upper line termination. Switch one simulates a device on the

internal 50-pin connector, switch two simulates a device on the internal

68-pin connector, switch three forces the upper SCSI line terminator to

stay on, and switch four simulates a device on the external 68-pin

connector.

When LSIU40SE is in the middle of a bus using only one connector, then

switch Int68 and Ext68 (switches 2 and 4) for that bus are on. This forces

the terminators for that bus to be disabled.

2.2.11 Setting SCSI IDs

You must set each SCSI device and the host adapter to a separate SCSI

ID 0 through 15. 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 SCSI hard disk drive on the SCSI bus, that drive should have

SCSI ID 0, or the lowest SCSI ID on the bus. Chapter 3, “Conﬁguring the

LSIU40SE,” explains how to set your host adapter ID using the LSI Logic

SCSI BIOS Conﬁguration Utility.

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. You must have no duplication of

SCSI IDs on a SCSI bus.

Step 1. Determine the SCSI ID of each device on the SCSI bus. Note

any duplications and if 8-bit SCSI devices are to be used, the

host adapter ID must not be set above 7.

Step 2. Make any necessary changes to the SCSI IDs and record the

IDs for future reference. Table 2.1 is provided as a place to

keep this record.

2.2.12 Setting Interrupts

You should not normally have to change the default interrupt routing for

the LSIU40SE, since performance is usually increased by having two

separate interrupts. However, if your system does not support two

separate interrupts, jumper TP9 (see Figure A.1 on page A-2) is provided

to change the interrupt routing. Table 2.2 explains the jumper settings:

3.2 Starting the SCSI BIOS Conﬁguration Utility

If you have LSI Logic SCSI BIOS Version 4.xx, and it includes the

LSI Logic SCSI BIOS Conﬁguration Utility, you can change the default

conﬁguration of the SCSI host adapters. You may decide to alter these

default values if there is a conﬂict between device settings or if you need

to optimize system performance.

You can see the version number of your SCSI BIOS in a banner

displayed on your computer monitor during boot. If the utility is available,

the following message also appears on your monitor:

Press Ctrl-C to start LSI Logic Configuration Utility...

This message remains on your screen for about ﬁve seconds, giving you

time to start the utility. If you decide to press “Ctrl-C,” the message

changes to:

Please wait, invoking LSI Logic Configuration Utility...

After a brief pause, your computer monitor displays the Main Menu of the

LSI Logic SCSI BIOS Conﬁguration Utility.

NVRAM is available on the LSIU40SE. Changes can be made and stored

to NVRAM using this menu driven utility.

Important: This utility is a powerful tool. If, while using it, you somehow

disable all of your controllers, pressing Ctrl-A (or Ctrl-E on

version 4.04 or later) after memory initialization during

reboot allows you to re-enable and reconﬁgure.

Not all devices detected by the Conﬁguration Utility can be

controlled by the BIOS. Devices such as tape drives and

scanners require that a device driver speciﬁc to that

peripheral be loaded. The device driver is provided by the

device manufacturer.

3.2.1 Conﬁguration Utility Main Menu

When you start the LSI Logic SCSI BIOS Conﬁguration Utility, the Main

SCSI host adapters and information about each of them. The LSIU40SE

appears on the menu as two LSI53C875 entries; one for each channel.

To select an adapter, use only the arrow keys and enter key. Then, you

can view and/or change the current settings for that adapter and the

SCSI devices attached to it.

You can select an adapter only if Current Status is “On”. Changes are

possible since NVRAM is present on the host adapter.

Exit this menu

The settings in this menu are global settings that affect the selected host

adapter and all SCSI devices attached to it. One of these choices can

be selected by highlighting it and pressing Enter.

SCAM Support – The LSI Logic BIOS Version 4.xx and above supports

the SCSI Plug and Play protocol called SCAM (SCSI Conﬁgured

AutoMatically). SCAM support by default is off in adapter BIOS versions

4.09 and later for the LSI53C876 device. The user may choose to turn

this on only if the system drivers do not require SCAM off. Note that if

this BIOS is ﬂashed onto a board with existing settings, then these

settings are not changed to reﬂect the new BIOS defaults. Go into the

Conﬁguration Utility to change these settings.

3-8

Conﬁguring the LSIU40SE

Parity – The LSI Logic PCI to SCSI host adapters always generate

parity, but some older SCSI devices do not. Therefore, you are offered

the option of disabling parity checking.

Note:

When disabling parity checking, it is also necessary to

disable disconnects for all devices, as parity checking for

the reselection phase is not disabled. If a device does not

generate parity, and it disconnects, the I/O never completes

because the reselection never completes.

Host SCSI ID – This option refers to the host adapter’s SCSI ID, which

is a unique number used to identify the device on the SCSI bus.

Note:

In general, it is suggested that the user not change the host

adapter ID from the default value of 7, as this gives it the

highest priority on the SCSI bus. Please also note that if

you have 8-bit SCSI devices (narrow), they cannot see host

IDs greater than 7.

Scan Order – This option allows the user to tell the SCSI BIOS and

device drivers to scan the SCSI bus from low to high (0 to max) SCSI

ID, or from high to low (max to 0) SCSI ID. If there is more than one

device on the SCSI bus, changing the scan order changes the order in

which drive letters are assigned by the system. Drive order may be

reassigned differently in systems supporting the BIOS Boot Speciﬁcation

(BBS).

See the PCI Storage Device Management System SDMS 4.0 User’s

Guide, Chapter 2, “SCSI BIOS,” for additional information regarding BBS.

Note:

The scan order option may conﬂict with operating systems

that automatically assign a drive order.

Removable Media Support – This option deﬁnes the removable media

support for a speciﬁc drive. When this option is selected, a window

appears with three choices:

•

None

Boot Drive Only

With Media Installed

Starting the SCSI BIOS Conﬁguration Utility

3-9

None indicates there is no removable media support whether the

drive is selected in BBS as being ﬁrst, or ﬁrst in scan order in

non-BBS.

Boot Drive Only provides removable media support for a removable

hard drive if it is ﬁrst in the scan order.

With Media Installed provides removable media support wherever

the drive(s) actually resides.

One of these choices can be selected by highlighting it and pressing

Enter.

CHS Mapping – This option deﬁnes the cylinder head sector (CHS)

values that will be mapped onto a disk without pre-existing partition

information. SCSI Plug and Play Mapping is the default value.

To support interchange with noncompatible systems, there is another

option that can be selected by choosing CHS Mapping and then moving

the cursor to Alternate CHS Mapping.

Note:

Neither of these options will have any effect after the disk

has been partitioned with the FDISK command.

To remove partitioning, two options are available:

•

Reformat the disk using the Format Device option. See Section

3.2.3, “Device Selections Menu,” below.

Use the FDISK/MBR command at the C:\ prompt, where MBR

represents master boot record.

Important: Reformatting the disk or using FDISK/MBR erases all

partitioning and data that exists. Be careful when using

either the Format utility or the FDISK/MBR command that

you target the correct disk.

After clearing the partitions and data, it is necessary to

reboot and clear memory or the old partitioning data will be

reused, thus nullifying the previous operation.

Spinup Delay (seconds) – This option allows you to stagger spinups

for a longer period of time to balance the total current load. The default

value is 2 seconds with choices between 1 and 10 seconds.

3-10

Conﬁguring the LSIU40SE

device must agree to a width they can both handle. Only host adapters

that can do 16-bit data transfers have this option enabled.

Conﬁguring the LSIU40SE

Disconnect – SCSI devices have the ability to disconnect from the

initiator during an I/O transfer. This disconnect option frees the SCSI Bus

to allow other I/O processes. This option tells the host adapter whether

or not to allow a device to disconnect. Some devices run faster with

disconnects enabled (typically newer devices), while some run faster with

disconnects disabled (typically older devices).

Read/Write I/O Time-out (seconds) – This option sets the amount of

time the host adapter waits for a read, write, or seek command to

complete before trying the I/O transfer again. Since this provides a

safeguard allowing the system to recover if an I/O operation fails, it is

recommended that you always set the time-out to a value greater than

zero.

Note:

If the time-out is set to zero, then the I/O will never time-out.

Scan for Device at Boot Time – Set this option to No if there is a

device that you do not want to be available to the system. Also, on a bus

with only a few devices attached, you can speed up boot time by

changing this setting to No for all unused SCSI IDs.

Scan for SCSI Logical Units (LUNs) – Set this option to Noif problems

arise with a device that responds to all LUNs whether they are occupied

or not. For example, if there is a SCSI device with multiple LUNs but you

do not want all of those LUNs to be available to the system, then set this

option to No. This will limit the scan to LUN 0 only.

Queue Tags – This option allows the user to enable or disable the

issuing of queue tags during I/O requests when your device driver can

do this.

Initial Boot – This option allows any device attached to the ﬁrst adapter

to become the boot device. It provides the users of non-BBS personal

computers with some of the ﬂexibility of a BBS machine.

Format Device – If enabled, this option allows the user to low-level

format a magnetic disk drive. Low-level formatting will completely and

irreversibly erase all data on the drive. Formatting will default the drive to

a 512-byte sector size even if the drive had previously been formatted to

another sector size.

The dimensions of the LSIU40SE are 190 x 96.52 mm (7.50 x 3.80

inches). PCI connection is made through edge connector J1.

Internal 16-bit SCSI connection is made through the 68-pin high density

connectors J2 or J6. Internal 8-bit SCSI connection is made through the

50-pin low density connectors J4 or J8. External SCSI connection is

made through the 68-pin VHDCI connectors J3 or J7. The J3 and J7

connectors extend through the ISA/EISA bracket, which is attached to

the face of the connector outside the cabinet where the LSIU40SE is

installed.

The bracket is a standard ISA type with a cutout to accommodate the

connectors. The J5 and J9 connectors are for connecting the computer’s

Busy LED. It is a 4-pin one row right-angle header wired in parallel with

the on-board LED. The component height on the top and bottom of the

board follows the PCI Local Bus Speciﬁcation Revision 2.1 standard.

Technical Speciﬁcations

A.1.3 Thermal, Atmospheric Characteristics

The board is designed to operate in an environment deﬁned by the

following parameters:

•

Temperature range: 0 ˚C to 55 ˚C (dry bulb)

Relative humidity range: 0% to 90% noncondensing

Maximum dew point temperature: 32 ˚C

A.1.4 Electromagnetic Compliance

The board is designed and implemented to minimize electromagnetic

emissions, susceptibility, and the effects of electromagnetic discharge.

The board meets the requirements of FCC and CISPR Class B limits and

is marked with the FCC Self Certiﬁcation logo. It also carries the CE

mark.

A.1.5 Safety Characteristics

The bare board meets or exceeds the requirements of UL ﬂammability

rating 94 V0. The bare board is also marked with the supplier’s name or

trademark, type, and UL ﬂammability rating. Since this board is installed

in a PCI bus slot, all voltages are below the SELV 42.4 V limit.

A.2 Operational Environment

The LSIU40SE is designed for use in PCI computer systems with an

ISA/EISA bracket type. The LSI Logic SDMS software operates the

board, but the design of the board does not prevent the use of other

software.

A.2.1 The PCI Interface

The PCI interface operates as a 32-bit DMA bus master. The connection

is made through edge connector J1, which provides connections on both

the front and back of the board. The signal deﬁnitions and pin numbers

conform to the PCI Local Bus Speciﬁcation Revision 2.1 standard.

Table A.1 and Table A.2 show the signal assignments.

A.2.2 The SCSI Interface

The SCSI interface operates as 8-bit or 16-bit, synchronous or

asynchronous, SE bus, and supports SCSI-2 protocols and 16-bit

arbitration. The interface is made through connectors J2, J3 and J4 for

channel A. Channel B connectors are J6, J7, and J8. Connectors J2 and

J6 are 68-pin high density right-angle receptacles for internal

connections. Connectors J3 and J7 are 68-pin VHDCI right-angle

receptacles that protrude through the back panel bracket. Connectors J4

and J8 are 50-pin low density vertical shrouded headers used for internal

SCSI connections.

Note:

Up to two (and only two) connections are allowed on each

channel. Connecting to all three connectors on a channel

will result in an unreliable conﬁguration.

Active SE SCSI termination is provided automatically. SCSI termination

power is also supplied by the board. Table A.3 and Table A.4 show the

signal assignments for J2/J6, J3/J7, and J4/J8.
