MegaRAID SAS 9240-4i and SAS 9240-8i RAID Controllers

Quick Installation Guide

Thank you for purchasing the MegaRAID® SAS 9240-4i
RAID controller or the MegaRAID SAS 9240-8i RAID
controller. Before you install your RAID controller, please
take a few minutes to read this quick installation guide. If you
need more information about any topic covered in this guide,
refer to the related documents on your MegaRAID Universal
Software Suite CD.

Note

: Record your controller serial number in a safe

location in case you need to contact LSI.

The MegaRAID SAS 9240-4i RAID controller and the
MegaRAID SAS 9240-8i RAID controller are PCI-Express

2.0, half-size, full-height RAID controllers based on the
LSISAS2008 PCI Express-SAS/SATA I/O Processor chip.

The MegaRAID SAS 9240-4i RAID controller controls four
internal 6-Gb/s SAS/SATA ports through one SFF-8087 SAS
x4 internal connector.

The MegaRAID SAS 9240-8i RAID controller controls eight
internal 6-Gb/s SAS/SATA ports through two SFF-8087 SAS
x4 internal connectors.

There are two differences between the SAS 9240-4i RAID
controller and the SAS 9240-8i RAID controller:

– The SAS 9240-4i supports four ports and the SAS

9240-8i supports eight ports.

– The SAS 9240-4i does not have the connector for

ports four through seven.

Note

: SATA II is the only type of SATA supported by

these RAID controllers.

RAID CONTROLLER INSTALLATION

Back up your data before you change your
system configuration. Otherwise, you might lose
data.

Step 1 Unpack the RAID Controller

Unpack the RAID controller in a static-free
environment. Remove it from the antistatic bag,
and inspect it for damage. If the RAID controller
appears to be damaged, or if the MegaRAID
Universal Software Suite CD is missing, contact
LSI or your MegaRAID OEM support
representative.

The CD contains utility programs, device drivers
for various operating systems, and the following
documentation:

• MegaRAID 6Gb/s SAS RAID Controllers
User’s Guide

• MegaRAID SAS Software User’s Guide

• MegaRAID SAS Device Driver Installation

User’s Guide

• Software license agreement

Step 2 Prepare the Computer

Turn off the computer, and unplug the power
cords from the rear of the power supply. Remove
the cover from the computer.

Before you install the RAID controller, make sure
that the computer is disconnected from the power
and from any networks.

Step 3 Review the Jumpers and the Connectors

Figure 1 shows the location of the jumpers and

the connectors on the SAS 9240-4i RAID
controller. The jumpers are set at the factory, and
you usually do not need to change them.

Step 4 Install the RAID Controller

Insert the RAID controller in a PCI Express slot
on the motherboard, as shown in Figure 3. Press
down gently, but firmly, to seat the card correctly
in the slot. Secure the RAID controller to the
computer chassis with the bracket screw.

Note

: Some PCI Express slots support only PCI

Express graphics cards; if a RAID controller is
installed, it will not function.
