Thank you for purchasing the MegaRAID® SATA (Serial
Attached SCSI/Serial ATA II) 8308ELP (PCI Express lowprofile) RAID Controller. Please take a few minutes to read
this quick installation guide before you install the controller.
Note: This is a PCI Express x4 card, so it fits only in a
PCI Express x4 or greater slot.
Note: SATA II is the only type of SATA supported by the
8308ELP.
You can use the intelligent Battery Backup Unit 01
(LSIiBBU01) with the 8308ELP.

CONTROLLER INSTALLATION
Step 1 Unpack the MegaRAID SATA 8308ELP RAID
Controller
Unpack the controller in a static-free environment.
Remove it from the antistatic bag and inspect it
for damage.
If the controller appears to be damaged contact
LSI Logic or your MegaRAID OEM support
representative.
Step 2 Prepare the Computer
Turn off the computer and unplug the power
cord(s) from the back of the power supply.
Remove the cover from the computer.
Step 3 Review the Jumpers and Connectors
Figure 1 shows the location of the jumpers and
connectors on the 8308ELP. The jumpers are set
at the factory and you usually do not need to
change them.

Note: J11, the battery backup connector, is located on
the back side of the 8308ELP.
Make a backup of your data before you change
your system configuration. Otherwise, you may
lose data.

II devices. Refer to Figure 1 to view connector
locations on the controller.
Jumper/
Connector Type Description
J1
IPMI-style I2C
Debug header
(Intelligent Platform Management
Interface)
3-pin connector.
Used for diagnostic purposes.
J2 Individual Activity
LED header for all
eight ports
16-pin (8x2) header.
Provides LED interface individually
to eight SATA ports. The LED indicates activity on particular ports.
