Installations
This section provides information on how to use the jumpers and
connectors on the 3307980 in order to set up a workable system. The topics

Installing the Memory
The 3307980 board supports one SODIMM DDR memory socket for a
maximum total memory. The memory module capacities supported are
128MB, 256MB, 512MB and 1GB.
Installing and Removing Memory Modules
To install the DDR modules, locate the memory slot on the board and
perform the following steps:
1. Hold the DDR module so that the key of the DDR module align with
those 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 DDR module, press the clips with both hands.

7
Setting the Jumpers
Jumpers are used on 3307980 to select various settings and features
according to your needs and applications. Contact your supplier if you
