5.3 DIMM Module Replacement
The subsystem comes with a pre-installed 256MB capacity or above DDR
RAM DIMM module on the controller. The controller supports memory up
to 1GB. If a DDR RAM DIMM module has been failed or a different size of
DIMM module needs to be used, the pre-installed module must be removed
and the new one installed. Replacement and installation instructions are
described fully below.
5.3.1 DIMM Module Considerations
If the memory module on the controller module is going to be replaced, the
following issues must be considered when purchasing a replacement DIMM
module:
• Pre-installed DDR RAM DIMM module: The FALCON II RAID
subsystem comes with a 256MB capacity or above DDR RAM DIMM
pre-installed on the controller board and can support up to 1GB
capacity. If you wish to change the size of the DDR DIMM, then a new
DIMM must be installed.
• Purchasing considerations: When purchasing a DDR RAM DIMM
module to install on the FALCON II controller board, contact your
subsystem vendor for an updated list of compatible DIMM modules.
• DDR RAM DIMM module supported: The FALCON II supports
DDR RAM DIMM modules with memory capacities between 256MB
and 1GB.
• Installation considerations: When installing the DDR RAM DIMM
module, it is necessary to remove the controller module. The controller
