Installing a SODIMM for Expandable Memory
The SODIMM plugs into the memory slot and is designed to be used in the NetVanta 3430 and
NetVanta 3448 to provide a maximum of 1 GB of DDR memory.
The SODIMM is intended to be installed only by qualified personnel.
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 three 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 32 on page 72. 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 33 on page 72) 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 34 on page 72. 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.
