2.1 Essential Installations Before You Begin
Follow the instructions below to install the memory.
2.1.1 Installing the Memory
The MB991AF board supports four DDR4 memory sockets for a maximum
total memory of 64 GB. To install the modules, locate the memory slot on the
board and perform the following steps:
1. Press the ejector tab of the memory slot down and outwards with your
fingertips.
2. Hold the meomry module and align the key of the module with that on
the memory slot.
3. Gently push the module in an upright position unitl the ejector tabs of
the memory slot close to hold the module in place whne the module
touches the bottom of the slot.
To remove the module, press the ejector tabs outwards with your fintertips to

2.2 Setting the Jumpers
Set up and configure your MB991AF by using jumpers for various settings
and features according to your needs and applications. Contact your
supplier if you have doubts about the best configuration for your use.
2.2.1 How to Set Jumpers
Jumpers are short-length conductors consisting of several metal pins with a
non-conductive base mounted on the circuit board. Jumper caps are used to
have the functions and features enabled or disabled. If a jumper has 3 pins,
you can connect either PIN1 to PIN2 or PIN2 to PIN3 by shorting.

When two pins of a jumper are encased in a jumper cap, this jumper is
closed, i.e. turned On.
When a jumper cap is removed from two jumper pins, this jumper is open,
i.e. turned Off.
