INSTALLATIONS

Installing the Memory

The MB839 board supports one DDR3 memory socket that can support
up to 8GB memory, DDR3L (w/o ECC function).

Installing and Removing Memory Modules

To install the DDR3L module, locate the memory slot on the board and
perform the following steps:

1. Hold the DDR3L module so that the key of the DDR3L module aligns

with that on the memory slot. Insert the module into the socket at a
slight angle (approximately 30 degrees). Note that the socket and
module are both keyed, which means that the module can be installed
only in one direction.

2. To seat the memory module into the socket, apply firm and even

pressure to each end of the module until you feel it slip down into the
socket.

3. With the module properly seated in the socket, rotate the module

downward. Continue pressing downward until the clips at each end
lock into position.

4. To remove the DDR3L module, press the clips with both hands.

JP12: System Function Connector

JP12 provides connectors for system indicators that provide light
indication of the computer activities and switches to change the computer
status. JP12 is a 8-pin header that provides interfaces for the following
functions

Pin 1,2: Power LED

The power LED indicates the status of the main power switch.

Pin 3,4: ATX Power ON Switch

Pin 3 & 4 are for “ATX Power Supply On/Off Switch” on the

system that connects to the power switch on the case. When
pressed, the power switch will force the system to power on. When
pressed again, it will force the system to power off.

10

Pin 5, 6: Hard Disk Drive LED Connector

This connector connects to the hard drive activity LED on control

panel. This LED will flash when the HDD is being accessed.

Pin 7, 8: Reset Switch

The reset switch allows the user to reset the system without turning

the main power switch off and then on again. Orientation is not
required when making a connection to this header.
