Safety Instructions
Use the following safety guidelines to help protect your computer system from potential
damage and to ensure your own personal safety.
When Using Your Computer System
As you use your computer system, observe the following safety guidelines:
CAUTION:
Do not operate your computer system with any cover(s) (such as computer
covers, bezels, filler brackets, and front-panel inserts) removed:
8
•To help avoid damaging your computer, be sure the voltage selection switch on the power
supply is set to match the alternating current (AC) power available at your location:
–115 volts (V)/60 hertz (Hz) in most of North and South America and some Far
Eastern countries such as Japan, South Korea, and Taiwan
–230 V/50 Hz in most of Europe, the Middle East, and the Far East. Also be sure your
monitor and attached peripherals are electrically rated to operate with the AC power
available in your location.
•To help avoid possible damage to the system board, wait five seconds after turning off
the system before removing a component from the system board or disconnecting a
peripheral device from the computer.
•To help prevent electric shock, plug the computer and peripheral power cables into
properly grounded power sources. These cables are equipped with 3-prong plugs to
ensure proper grounding. Do not use adapter plugs or remove the grounding prong from
a cable. If you must use an extension cable, use a 3-wire cable with properly grounded
plugs.
•To help protect your computer system from sudden, transient increases and decreases in
electrical power, use a surge suppressor, line conditioner, or uninterruptible power supply.
•Be sure nothing rests on your computer system’s cables and that the cables are not located
where they can be stepped on or tripped over.
•Do not spill food or liquids on your computer. If the computer gets wet, consult the
documentation that came with it.
•Do not push any objects into the openings of your computer. Doing so can cause fire or
electric shock by shorting out interior components.
•Keep your computer away from radiators and heat sources. Also, do not block cooling
vents. Avoid placing loose papers underneath your computer; do not place your computer
in a closed-in wall unit or on a rug.
When Working Inside Your Computer
Notice:Do not attempt to service the computer system yourself, except as explained in
this guide and elsewhere in Intel documentation. Always follow installation and
service instructions closely.
1. Turn off your computer and any peripherals.
2. Disconnect your computer and peripherals from their power sources. Also disconnect an y
telephone or telecommunications lines from the computer.
Doing so reduces the potential for personal injury or shock.
Also note these safety guidelines:
•When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the
cable itself. Some cables have a connector with locking tabs; if you are disconnecting this
type of cable, press in on the locking tabs before disconnect the cable. As you pull
connectors apart, keep them evenly aligned to avoid bending any connector pins. Also,
before you connect a cable, make sure both connectors are correctly oriented and aligned.
•Handle components and cards with care. Don’t touch the components or contacts on a
card. Hold a card by its edges or by its metal mounting bracket. Hold a component such
as a microprocessor chip by its edges, not by its pins.
9
Protecting Against Electrostatic Discharge
Static electricity can harm delicate components inside your computer. To prevent static
damage, discharge static electricity from your body before you touch any of your computer’s
electronic components, such as the microprocessor. You can do so by touching an unpainted
metal surface, such as the metal around the card-slot openings at the back of the computer.
As you continue to work inside the computer, periodically touch an unpainted metal surface
to remove any static charge your body may have accumulated. In addition to the preceding
precautions, you can also take the following steps to prevent damage from electrostatic
discharge (ESD):
•When unpacking a static-sensitive component from its shipping carton, do not remove the
component from the antistatic packing material until you are ready to install the
component in your computer. Just before unwrapping the antistatic packaging, be sure to
discharge static electricity from your body.
•When transporting a sensitive component, first place it in an antistatic container or
packaging.
•Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads
and workbench pads.
This section provides a general overview of the Intel® RAID Controller SRCU42X . It
consists of the following sections.
•Section 1.1, “Overview,” page 15
•Section 1.2, “Features,” page 16
•Section 1.3, “Hardware,” page 17
1.1Overview
The Intel RAID Controller SRCU42X is a high-performance intelligent Peripheral
Component Interconnect to Small Computer System Interface (PCI-to-SCSI) host adapter
with Redundant Array of Independent Disks (RAID) control capabilities. The SRCU42X
controller provides reliability, high performance , and fault-tolerant disk subsystem
management. It is an ideal RAID solution for the internal storage of workgroup,
departmental, and enterprise systems.The SRCU42X controller offers a cost-effective way to
implement RAID in a server.
The SRCU42X controller (dual-channel) has one LSI* 53C1030 controller chip that controls
two SCSI channels. The SRCU42X controller has two VHDCI 68-pin external SCSI
connectors and two HDCI 68-pin internal SCSI connectors. The SRCU42X controller is a
PCI-X controller.
The SRCU42X controller supports a low voltage differential (LVD) or a single-ended (SE)
SCSI bus. With LVD, you can use cables up to 12 meters long. Throughput on each SCSI
channel can be as high as 320 Mbytes/s.
You can install the Intel RAID Controller SRCU42X in PCI-X computer systems with a
standard bracket type. With this adapter in your PCI or PCI-X system, you can connect SCSI
devices over a SCSI bus.
For Ultra320 SCSI performance, you must connect only LVD devices to the bus. Do not mix
SE with LVD devices, or the bus speed will be limited to the slower SE (Ultra SCSI) SCSI
data transfer rates. Do not connect a high voltage differential (HVD) device to the SCSI bus
because the chip on the SRCU42X controller must be reset to return to LVD or SE mode
once the HVD device is removed.

1.3.2Configuration on Disk
Configuration on Disk saves configuration information both in NVRAM on the Intel RAID
Controller SRCU42X and on the disk drives attached to the SRCU42X controller. If the
SRCU42X controller is replaced, the new SRCU42X controller detects the actual RAID
configuration from the configuration information on the drives. This maintains the integrity
of the data on each drive, even if the drives have changed their target ID.
Note:
1.3.3Drive Roaming
The Intel RAID Controller SRCU42Xs support drive roaming across channels on the same
SRCU42X controller. Drive roaming lets an Intel Raid SRCU42X controller detect the actual
RAID configuration, maintaining the integrity of the data on each disk drive, even if the disk
drives have changed channels and/or target ID.
Note:
Configuration on Disk does not work if you change both the SRCU42X
controller and the SCSI connectors to different connectors on the new
SRCU42X controller. It works only if you make one change at a time.
Intel RAID Controller SRCU42Xs do not support drive roaming across
channels when cluster mode is enabled.

6) Set the Target IDs.
Set target identifiers (TIDs) on the SCSI devices. Each device in a channel must have a
unique TID. Provide unique TIDs for non-disk devices (CD-ROM or tapes), regardless
of the channel where they are connected. The Intel RAID Controller SRCU42X
automatically occupies TID 7, which is the highest priority. The arbitration priority for a
SCSI device depends on its TID.

Detailed Installation21
7) Connect SCSI Devices to the Storage Adapter
Use SCSI cables to connect SCSI devices to the SRCU42X controller.
To connec t the SCSI devices:
a. Disable termination on any SCSI device that does not sit at the end of the SCSI bus.
b. Configure all SCSI devices to supply TERMPWR.
c. Connect cables to the SCSI devices. The maximum cable length for Fast SCSI (10
Mbytes/s) devices or SE is 3 meters; it is 1.5 meters for Ultra SCSI devices; it is
12 meters for LVD devices. You can connect up to 15 Ultra SCSI devices to each
SCSI channel.
System throughput problems can occur if SCSI cables are not the correct type. To
minimize the potential for problems:
–Use cables no longer than 12 meters for Ultra160 and Ultra320 devices.
–For SE SCSI devices, use the shortest SCSI cables (no longer than 3 meters
for Fast SCSI, no longer than 1.5 meters for an 8-drive Ultra SCSI system,
and no longer than 3 meters for a 6-drive Ultra SCSI system).
–Use active termination.
–Avoid clustering the cable nodes.
–The cable stub length must be no greater than 0.1 meter (4 inch es.)
–Use high impedance cables.
–Route SCSI cables carefully.
8) Set SCSI Termination
The SCSI bus is an electrical transmission line and must be terminated properly to
minimize reflections and losses. Set termination at each end of the SCSI cable(s).
For a disk array, set SCSI bus termination so that removing or adding a SCSI device does
not disturb termination. An easy way to do this is to connect the SRCU42X controller to
one end of the SCSI cable and to connect an external terminator module at the other end
of the cable. You can then connect SCSI disk drives to the connectors between the two
ends of the cable. If necessary, disable termination on the SCSI devices. (This is not
necessary for Ultra320 and Ultra160 SCSI drives.)
Set the termination so that SCSI termination and TermPWR are intact when any disk
drive is removed from a SCSI channel, as shown in Figure 2.3.

9) Power On Host System
Replace the computer cover, and reconnect the AC power cords. Turn power on to the
host computer. Ensure that the SCSI devices are powered up at the same time as, or

might not be recognized.
During boot, a BIOS message appears.
The firmware takes several seconds to initialize. During this time, the SRCU42X
controller scans the SCSI channel(s).
The BIOS Configuration utility prompt times out after several seconds. The second portion
of the BIOS message displays the Intel RAID Controller SRCU42X number, firmware
version, and cache SDRAM size. The numbering of the controllers follows the PCI slot
scanning order used by the host motherboard.

Detailed Installation23
2.4After You Have Installed the Storage Adapter
After installation, you must configure the SRCU42X controller and install the operating
system driver. The Intel RAID Software User’s Guide instructs you about the configuration
options and how to set them on your SRCU42X controller.
PCI is a high-speed standard local bus for interfacing I/O components to the processor and
memory subsystems in a server. The component height on the top and bottom of the
SRCU42X controller follow the PCI Local Bus Specification, Revision 2.2, and PCI-X Addendum to the PCI Local Bus Specification, Revision 1.0a. The Intel RAID Controller
SRCU42X is used in PCI-X and PCI computer systems with PCI standard bracket types.

Glossary of Terms and Abbreviations
Active
Termination
The electrical connection required at each end of the SCSI bus, composed of active voltage
regulation and a set of termination resistors. Ultra SCSI, Ultra2 SCSI, Ultra160 SCSI, and
Ultra320 SCSI require active termination.
BIOSBasic Input/Output System. Software that provides basic read/write capability. Usually kept
as firmware (ROM based). The system BIOS on the mainboard of a computer is used to boot
and control the system. The SCSI BIOS on your host adapter acts as an extension of the
system BIOS.
ConfigurationRefers to the way a computer is setup; the combined hardware components (computer,
monitor, keyboard, and peripheral devices) that make up a computer system; or the software
settings that allow the hardware components to communicate with each other.
Device DriverA program that allows a microprocessor (through the operating system) to direct the operation
of a peripheral device.
Differential
SCSI
A hardware configuration for connecting SCSI devices. It uses a pair of lines for each signal
transfer (as opposed to Single-Ended SCSI which references each SCSI signal to a common
ground).
Domain
Validation
EEPROMElectronically Erasable Programmable Read Only Memory. A memory chip typically used to

External SCSI
Device
Fusion-MPT
Architecture
A SCSI device installed outside the computer cabinet. These devices are connected together
using specific types of shielded cables.
Fusion-MPT (Message Passing Technology) architecture consists of several main elements:
Fusion-MPT firmware, the Fibre Channel and SCSI hardware, and the operating system level
drivers that support these architectures. Fusion-MPT architecture offers a single binary,
operating system driver that supports both Fibre Channel and SCSI devices now.
HostThe computer system in which a storage adapter is installed. It uses the storage adapter to
transfer information to and from devices attached to the SCSI bus.

synonymous with RAM).
31
NVRAMNonVolatile Random Access Memory. Actually an EEPROM (Electronically Erasable Read
Only Memory chip) used to store configuration information. See EEPROM.
PCI and PCI-XPeripheral Component Interconnect. A high performance local bus specification that allows
connection of devices directly to computer memory. The PCI Local Bus allows transparent
upgrades from 32-bit data path at 33 MHz to 64-bit data path at 33 MHz, and from 32-bit
data path at 66 MHz to 64-bit data path at 66 MHz.
Peripheral
Devices
A piece of hardware (such as a video monitor, disk drive, printer, or
CD-ROM) used with a computer and under the computer’s control. SCSI peripherals are
controlled through a SCSI SRCU42X controller (host adapter).
SCSI BusA storage adapter (host adapter) and one or more SCSI peripherals connected by cables in a
linear configuration. The adapter may exist anywhere on the bus, allowing connection of both
internal and external SCSI devices. A system may have more than one SCSI bus by using a
multi-channel adapter or by using multiple adapters.
SCSI DeviceAny device that conforms to the SCSI standard and is attached to the SCSI bus by a SCSI
cable. This includes SCSI storage adapters (host adapters) and SCSI peripherals.
SCSI IDA 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 through 15 for Wide SCSI). The storage
adapter (host adapter) usually gets the highest ID (7 or 15) giving it priority to control the bus.
Single-Ended
SCSI
A hardware specification for connecting SCSI devices. It references each SCSI signal to a
common ground. This is the most common method (as opposed to differential SCSI, which
uses a separate ground for each signal).
TolerANTA technology developed and used by Intel to improve data integrity, data transfer rates, and
noise immunity through the use of active negation and input signal filtering.
Ultra SCSIA standard for SCSI data transfers. It allows a transfer rate of up to
20 Mbytes/s over an 8-bit SCSI bus and up to 40 Mbytes/s over a 16-bit SCSI bus.
Ultra2 SCSIA standard for SCSI data transfers. It allows a transfer rate of up to
40 Mbytes/s over an 8-bit SCSI bus, and up to 80 Mbytes/s over a
16-bit SCSI bus.
Ultra160 SCSIA standard for SCSI data transfers. It allows a transfer rate of up to 160Mbytes/s over a 16-
bit SCSI bus.
Ultra320 SCSIA standard for SCSI data transfers. It allows a transfer rate of up to 320Mbytes/s over a 16-
bit SCSI bus.
VHDCIVery High-Density Cable Interconnect. This cable is used to connect external connectors to
your storage adapter.
