J4	Mode Select	2-pin connector.
	header	If the ﬁrmware ﬂashed onto the board
		If the ﬁrmware ﬂashed onto the board
		is corrupted, you need to jumper J4
		(this holds the CPU core in reset), so
		you can ﬂash the ﬁrmware. Remove
		the jumper after you ﬂash the new
		ﬁrmware.
		No jumper: This is the setting during
		normal operation (Mode 3). This is
		the default.
		Jumper: This holds the CPU core in
		reset (Mode 0).
		Note: The card does not function as
		a RAID controller if this jumper is
		mounted.

Refer to your mainboard guide for information about the PCI-E slot.Step 5 Conﬁgure and Install SAS and/or SATA II Devices

Conﬁgure the SAS and/or SATA II devices and install them in the host system computer case.

Refer to the documentation for the devices for any pre-installation conﬁguration requirements.

Step 6 Connect the MegaRAID SAS 8344ELP RAID Controller to the SAS and/or SATA II Devices

Use SAS cables to connect the SAS 8344ELP to SAS and/or SATA II devices. Refer to Figure 1 to view connector locations on the controller.

Refer to the MegaRAID SAS Storage Adapters User’s Guide on the MegaRAID Universal Software Suite CD for detailed information about the SAS cables.
