MegaRAID 320-2E 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 320-2E. Each
step is explained more fully in the following table:

Step Action

1 Unpack the MegaRAID SCSI 320-2E.
2 Turn off the computer, removethe power cord, and remove the cover.
3 Verify the MegaRAID SCSI 320-2E jumper settings.
4 Install the MegaRAID SCSI 320-2E.
5 Connect the SCSI devices to the MegaRAID SCSI 320-2E.
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 320-2E

Unpack and install the MegaRAID SCSI 320-2E Controller in a
static-free environment. Remove the MegaRAID SCSI 320-2E from
the antistatic bag and inspect it for damage.

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: Review the MegaRAID Controller Jumpers

Make sure the jumper settings on the MegaRAID SCSI 320-2E 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 Write Pending Indicator

(Dirty Cache LED)

J2 Onboard BIOS Enable 2-pin header.

2

C Header 2-pin header. Reserved.

J4 I
J5 SCSI Termination Enable

Channel 0

J6 SCSI Termination Enable

Channel 1

J7 Serial Port (RS232) 3-pin connector.

2-pin header.
Connector for enclosure LED to indicate when

data in the cache has yet to be written to the
device. Optional.

No jumper = Enabled (default setting)
Jumpered = Disabled

2-pin header.
Jumper pins 1–2 to enable software control of

SCSI termination through drive detection
Jumper pins 2–3 to disable onboard SCSI

termination.
No jumper installed enables onboard SCSI

termination. (Refer to J17 and J18.) This is
the default.

Connector is for diagnostic purposes.
Pin 1 – RXD (Receive Data)
Pin 2 – TXD (Transmit Data)
Pin 3 – GND (Ground)

Step 4: Install the MegaRAID SCSI 320-2E Controller

Install the MegaRAID SCSI 320-2E Controller in a PCI-Express 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 320-2E 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.
Applying pressure could break the module.

Step 5: Connect SCSI Devices to the MegaRAID Controller

Connect SCSI devices to the internal, high-density, 68-pin SCSI
connectors (J9 and J10) and/or the external, very-high density,
68-pin SCSI connectors (J12 and J14). To achieve maximum data
throughput, use only Ultra320 SCSI devices. The MegaRAID SCSI
320-2E Controller supports up to 30 Ultra320 SCSI devices at a
maximum SCSI bus cable length of 12 meters. You also can
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 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 the Target IDs for the 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 0–6. The MegaRAID SCSI 320-2E Controller is
automatically assigned TID 7, which has the highest priority. Verify
that no two SCSI 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.

32-Bit Slot (3.3 V)

64-Bit Slots (5 V)

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.
