The following table lists the jumpers and connectors on the
MegaRAID 320-2X controller.

Step 4

Check the Memory Module.

Ensure that the memory is present and seated
firmly in the DIMM socket.

Note:

For more information about supported memory,
contact Technical Support. Refer to the
Technical Support section in this document for
contact information.

Step 5

Install the RAID Controller.

Install the MegaRAID 320-2X in a 3.3 V PCI or
PCI-X slot, as shown in

Figure 2

. Press down

gently, but firmly, on the top edge of the card to
seat the card properly in the slot. The bottom
edge of the controller card must be flush with the
slot. Attach the MegaRAID 320-2X to the
computer chassis with the bracket screw.

If your board has a memory module, never apply
pressure to the module when inserting the adapter.
Applying pressure could break the module.

Step 6

Connect SCSI Devices to the RAID Controller.

Connect the SCSI devices to the internal,
high-density, 68-pin SCSI connectors (J5 and J6)
and/or the external, very high-density, 68-pin

Item Connector
