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 Figure 41 on page 79) 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
Figure 39 on page 79. 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 Figure 40 on page 79) 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 Figure 41 on
page 79. 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.
