Upgrading Memory

You can upgrade an SSG 20 device from a single 128 MB dual in-line memory module (DIMM) dynamic random access memory (DRAM) to a 256 MB DIMM DRAM.

To upgrade the memory on an SSG 20 device, perform the following steps:

1.Attach an ESD grounding strap to your bare wrist and connect the strap to the ESD point on the chassis or to an outside ESD point if the device is disconnected from earth ground.

2.Unplug the AC cord from the power outlet.

3.Turn over the device so that its top is lying on a flat surface.

4.Use a phillips screwdriver to remove the screws from the memory-card cover. Keep the screws nearby for use when securing the cover later.

5.Remove the memory-card cover.
