MegaRAID 320-1 Controller Installation
Caution: Make a backup of your data before you change your
system configuration. Otherwise you may lose data.
Follow these steps to install the MegaRAID SCSI 320-1. Each step
is explained more fully in the following text:
Step Action
1 Unpack the MegaRAID SCSI 320-1.
2 Turn off the computer, removethe power cord, and remove the cover.
3 Check the MegaRAID SCSI 320-1 jumper settings.
4 Install the MegaRAID SCSI 320-1.
5 Connect the SCSI devices to the MegaRAID SCSI 320-1.
6 Set the target IDs for the SCSI devices.
7 Set SCSI termination.
8 Replace the computer cover and turn the power on.
9 Run the MegaRAID BIOS Configuration Utility.
10 Install the operating system driver.
Step 1: Unpack the MegaRAID SCSI 320-1
Unpack and install the MegaRAID SCSI 320-1 Controller in a
static-free environment. Remove the MegaRAID SCSI 320-1 from
the antistatic bag and inspect it for damage. If it appears to be
damaged, or if the Driver and Documentation CD is missing,
contact LSI Logic or your MegaRAID OEM support representative.
Step 2: Prepare the Computer
Turn off the computer and remove the power cord from the back of
the power supply. Remove the cover from the chassis. Make sure
the computer is disconnected from the power and from any
networks before installing the controller card.
Step 3: Check the MegaRAID Controller Jumpers
Make sure the jumper settings on the MegaRAID SCSI 320-1 are
correct. The jumpers are set at the factory, and you probably do not
need to change them. The following table lists the jumpers and
connectors on the RAID controller.
Item Description Type
J1 Internal high-density SCSI connector. 68-pin connector
J2 Dirty cache LED: This can be connected to
an LED on the computer enclosure. The LED
is lit when data in the cache has not yet been
written to the storage device.
J3 Clears EPROM configuration data. 2-pin header
J4 Enables or disables the MegaRAID onboard
BIOS. Leave the BIOS enabled (no jumper).
J5 SCSI activity indicator: This can be
connected to the hard disk LED on the
computer case to show SCSI bus activity.
J6 Serial port. For test purposes only. 3-pin connector
J7 External very high-density SCSI connector. 68-pin connector
J8 Battery backup board connector. 40-pin connector
J9 SCSI bus termination power: Leave at the
default setting (jumper installed) to allow the
PCI bus to provide termination power.
J10 SCSI termination control: Leave at the default
setting (jumper on pins 1 and 2) to allow the
MegaRAID SCSI 320-1 to automatically set
its own SCSI termination.

Step 4: Install the MegaRAID SCSI 320-1 Controller
Install the MegaRAID SCSI 320-1 Controller in a 3.3 V or 5 V PCI slot,
as shown in the following figure. Press down gently,but firmly,to make
sure that the card is properly seated in the slot. The bottom edge of
the controller card must be flush with the slot. Attach the MegaRAID
SCSI 320-1 to the computer chassis with the bracket screw.
Caution: If your board has a memory module, never apply
pressure to the module when inserting the adapter.

length of 12 meters. You can also connect Ultra160 and Ultra2
SCSI devices. The MegaRAID 320 Storage Adapters User’s Guide
lists the maximum number of devices and maximum cable length
for each kind of SCSI device.
Disable SCSI termination on all devices that are not connected at
the end of the SCSI bus. Use only high-quality ribbon SCSI cables
for internal devices and high-quality round SCSI cables for
external devices.
Step 6: Set Target IDs for SCSI Devices
Each connected SCSI device must have a unique Target ID (TID),
ranging from 0 to 15 for 16-bit devices. Note that under the DOS
Advanced SCSI Programming Interface, SCSI devices are limited
to SCSI IDs 1–6. The MegaRAID SCSI 320-1 Controller is
automatically assigned TID 7, which has the highest priority. Check
all SCSI devices to make sure that no two devices are set to the
same TID. Change the TIDs as needed. Refer to the SCSI device
documentation if you are not sure how to do this.
Step 7: Set SCSI Termination
The SCSI bus, which consists of connected SCSI cables and SCSI
devices, is an electrical transmission line that must be terminated
properly to minimize signal reflections and prevent data loss. Disk
enclosures normally handle termination for the SCSI devices in the
enclosure. Refer to your enclosure documentation for details.
SCSI termination must be set at each end of the SCSI bus, as
shown in the following figure. In this example, only internal SCSI
devices are connected to the MegaRAID SCSI 320-1. The
MegaRAID SCSI 320-1 automatically terminates its end of the SCSI
bus if only internal devices or only external devices are connected
to the SCSI bus. It automatically disables termination if both internal
and external devices are connected to the bus, because the
MegaRAID SCSI 320-1 is then in the “middle” of the bus.

Step 5: Connect SCSI Devices to MegaRAID Controller
Connect SCSI devices to the internal high-density 68-pin SCSI
connector (J1) and/or the external very high-density 68-pin SCSI
connector (J7). To achieve maximum data throughput, use only
Ultra320 SCSI devices. The MegaRAID SCSI 320-1 Controller
supports up to 15 Ultra320 devices at a maximum SCSI bus cable

(Termination Disabled on Both)
For a disk array, set SCSI bus termination so that removing or
adding a SCSI device does not disturb termination. To do this,
connect the MegaRAID SCSI 320-1 Controller to one end of the
SCSI cable and connect a SCSI terminator module at the other end
of the cable. Attach SCSI devices to the connectors between the
two ends, and disable termination on them. The following figure
shows an external drive enclosure with seven SCSI drives.
Termination is enabled at the end of the cable closest to the “last”
SCSI drive, which is assigned SCSI ID6.

Step 8: Power Up the Computer
Replace the computer cover and connect the power cords to all the
SCSI devices and to the computer. Turn on the power to all devices.
Be sure the SCSI devices are powered up before the computer or
at the same time as the computer. Otherwise, the computer may
not recognize the SCSI devices.
Observe the messages that appear during the boot process, until
you see the message:
Press <Ctrl><M> to run MegaRAID SCSI 320-1 BIOS Configuration
Utility
Step 9: Run the MegaRAID BIOS Configuration Utility
When the message “Press <Ctrl><M>” appears on the screen,
press <Ctrl><M> immediately to run the MegaRAID BIOS
Configuration Utility. See the MegaRAID Configuration Software
User’s Guide on the Universal Driver Suite CD for information about
how to run and use this program.
Supported RAID Levels
The MegaRAID SCSI 320-1 Controller supports disk arrays using
the following RAID levels:
• RAID 0 (Data striping): Data is striped across all disks in the
array, enabling very fast data throughput. There is no data
redundancy. All data is lost if any disk fails. (1–15 disk drives)
• RAID 1 (Disk mirroring): Data is written simultaneously to two
disks, providing complete data redundancy in case one disk fails.
The array capacity is half of total disk space. (2 disk drives)
• RAID 5 (Disk striping with distributed parity): Data is striped
across all disks in the array. Part of the capacity of each disk
stores parity information that reconstructs data if a disk fails.
Provides good data throughput for applications with high read
request rates. (3–15 disk drives)
• RAID 10 (RAID 1 and RAID 0 in spanned arrays): Uses
mirrored pairs of disks to provide complete data redundancy.
Provides high data throughput rates. (4–14 disk drives)
• RAID 50 (RAID 5 and RAID 0 in spanned arrays): Uses both
parity and disk striping across multiple disks to provide
complete data redundancy. Provides high data throughput rates.
(6–15 disk drives)
Step 10:Install the Operating System Driver
The MegaRAID SCSI 320-1 can operate under MS-DOS or any
DOS-compatible operating system using the standard AT BIOS INT
13h Hard Disk Drive interface. To operate with other operating
systems, you must install software drivers.
The Universal Driver Suite CD includes drivers for the operating
systems. In addition, you can view the supported operating systems
and download the latest drivers for RAID adapters on the LSI Logic
web site at http://www.lsilogic.com/downloads/selectDownload.do.
Access the download center and follow the steps to download
the driver.
Refer to the MegaRAID Device Driver Installation User’s Guide on
the Universal Driver Suite CD for information about installing the
driver. Be sure to use the latest Service Packs provided by the
operating system manufacturer and review the readme file that
accompanies the driver.
