Installing a SODIMM for Expandable Memory
The SODIMM plugs into the memory slot and is designed to be used in the NetVanta 1600 Series to provide a
maximum of 1 GB of memory. SODIMMs can be safely installed by following these instructions:
•
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, please refer to

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.
