Installing DIMMs
Adding memory to your device is an easy way to make programs run faster. You
can increase the amount of memory in your device by installing additional
dual-inline memory modules (DIMMs). Your device uses a noninterleaved
memory configuration.
When you install additional memory, note the following information:
• Memory modules are installed on the system board in the DIMM slots shown
in Figure 4-5. Devices with a single DIMM should have the module installed
in DIMM slot 1. For devices with two DIMMs, use slots 1 and 3. For devices
with four DIMMs use slots 1, 2, 3 and 4.
• Review the memory specifications for your WAE model in the “Appliance
Specifications” section on page A-1. Note the following information
regarding software support:
–
WAFS software supports up to 1 GB of memory.
–
ACNS software supports up to 512 MB of memory. ACNS software does
not recognize additional memory over 512 MB.
• When you install or remove DIMMS, the configuration information in the
device changes. Therefore, you must change and save the new configuration
information by using the Configuration/Setup Utility program. When you
restart the device, the system displays a message indicating that the memory
configuration has changed. Start the Configuration/Setup Utility program and
choose Save Settings. See Appendix D, “Using the Configuration/Setup
Utility Program,” for more information about using the Configuration/Setup
Utility program.
Figure 4-5 shows the location of the system-board connectors for installing
DIMMs.
