Upgrading Memory
You can upgrade a device that has a single 256 MB single in-line memory module
(SIMM) dynamic random access memory (DRAM) module to two 512 MB modules
(1GB of memory).
To upgrade the memory on an SSG 500-series device:
1. Attach an ESD grounding strap to your bare wrist, and connect the strap to the
ESD point on the device.
2. If the device is powered on, press and release the power button to power off the
device. Verify that the POWER LED is off.
3. Use a phillips screwdriver to remove the screws from the top panel of the
device. The screws are located at the rear and sides of the panel. Keep the
screws nearby for use when closing the device later.
4. Grip the rear edge of the top panel, lift it up, and then remove it.
5. Locate the memory module slots (see Figure 18).
NOTE: The device must have 1GB of memory installed to run ScreenOS content security
