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
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.

DIMM Module Replacement Procedure
NOTICE!
i
If you are going to replace or upgrade a DIMM module, please follow the instructions below. If
you do not want to replace or upgrade a DIMM module and would like to install a controller
module, please go to Section 6.2.3 Replacing the Controller Module.
If a DIMM module fails or if a DIMM module with a higher memory capacity is required, the
onboard DIMM module must be replaced. To replace the DIMM module:

Pre-installed DDR RAM DIMM module: The 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
RAID subsystem controller board, contact your subsystem vendor for an updated list of
compatible DIMM modules.
DDR RAM DIMM module supported: The RAID subsystem supports DDR RAM DIMM mod-
ules 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 board is more susceptible to damage than
the other components and must be handled with extreme care.
Secure installation: When replacing the DIMM module, make sure that the new DIMM
module is firmly in place prior to re-installing the controller module. If the DIMM module
is not firmly in place, the subsystem will not run and the whole procedure must be
repeated.
Remove the controller module. (See Section 6.2.2 Removing the Controller Module)
Remove the previously installed DIMM module from the DIMM socket. Pull down the
white clips on either side of the DIMM module to a 45-degree angle to dislodge the DIMM
module. (See Figure 6.6)
