Installing a SODIMM for Expandable Memory

The NetVanta 4430 ships with a 200-pin, 256 MB SODIMM (P/N 1200813E1) installed. It can be upgraded to provide 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 a 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.
4	Carefully lift and remove the unit’s cover to expose the circuit board.
5	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.
6	Gently insert the module into the memory slot at a slight angle (approximately 30 degrees) as
	shown in Figure 24 on page 56. Note that the socket and module are both keyed, which means
	the module can be installed one way only.
7	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 25 on page 56) 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.
8	With the module properly seated in the socket, rotate the module downward, as indicated in
	Figure 26 on page 56. 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.
9	Replace the unit cover, screws, and mounting brackets.
10	Restore power to the unit.
