Memory Upgrade
You can upgrade an SSG 20 device with a single 128 MB SODIMM DRAM memory
module to a 256 MB module.
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. Press and release the power button to power off the device. Verify that the
POWER LED blinks and then turns off.
3. Use a phillips screwdriver to remove the screws from the top panel of the
chassis. The screws are located at the rear and sides of the panel. Keep the
screws nearby for use when closing the chassis later.
4. Grip the rear edge of the top panel, lift it up, then remove it.
5. Locate the memory module slot.

8. Insert one of the 256 MB SODIMM DRAM memory modules into the slot from
which you just removed the 128 MB SODIMM DRAM memory module. Exerting
even pressure with both thumbs upon the upper edge of the module, press the
module downward until the locking tabs click into position.
