Installing SODIMM for Expandable Memory
The NetVanta 3430 ships with a 144-pin, 128 MB SODIMM (P/N 1200828G1) installed. It can be 
upgraded to provide a maximum of 512 MB of memory using the 144-pin, 512 MB SODIMM 
(P/N 1200829G1). 
The NetVanta 3448 ships with a 200-pin, 128 MB SODIMM (P/N 1200812E1) installed. It can be 
upgraded to provide 256 MB of memory using the 200-pin, 256 MB SODIMM (P/N 1200813E1) or 512 
MB using the 200-pin, 512 MB SODIMM (P/N 1200814E1). 
Follow these instructions to install a SODIMM module.
SODIMMs are intended to be installed only by qualified service personnel.
There are three types of SODIMM memory modules used by ADTRAN: 200-pin DDR1, 
200-pin DDR2, and 144-pin DDR2. Although these modules look very similar, they are 
not interchangeable. Prior to beginning the upgrade process, make sure you have 
purchased the correct upgrade module for your ADTRAN product.
Before touching electronic components, make sure you are properly grounded. By 
wearing a wrist strap (or using some other type of static control device), you can prevent 
static electricity stored on your body or clothing from damaging your installation. 
Instructions for Installing SODIMM
Step
Action
1
Remove power from the unit.
2
Remove the screws holding the base unit and the cover together, and, if necessary, the two mounting 
brackets.
3
Using a 3/16-inch hex driver, remove the two jack screws located on either side of the DB-9 port (if 
applicable).
4
Carefully lift and remove the unit’s cover to expose the circuit board.
5
Remove the old SODIMM by pulling outward on the clips (shown in 
) to release the 
module. Gently pull the module out of the memory slot.
6
Once you have discharged your static electricity, pick up the SODIMM by its top or sides. Do not touch the 
gold contacts at the bottom.
7
Gently insert the module into the memory slot at a slight angle (approximately 30 degrees) as shown in 
. Note that the socket and module are both keyed, which means the module can be 
installed one way only. 
8
To avoid damage, do not use excessive force. To seat the module into the socket, apply firm, even pressure 
to each end of the module (see the arrows in 
) until you feel it slip down into the 
socket. If you are having problems getting the module to seat properly, try rocking the module up and down 
slightly, while continuing to apply pressure. When properly seated, the contact fingers on the edge of the 
module will almost completely disappear inside the socket.
9
With the module properly seated in the socket, rotate the module downward, as indicated in 
. Continue pressing downward until the clips at each end of the socket lock into position. With most 
sockets, you will hear a distinctive CLICK, indicating the module is correctly locked into position. 
10
Replace the unit cover, screws, and mounting brackets.
11
Restore power to the unit.
