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 2GB. 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 AR3016G RAID
subsystem comes with a 256MB capacity or above DDR RAM DIMM
pre-installed on each controller board. If you wish to change the size of
the DDR DIMM, then a new DIMM must be installed.
•
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.

5.3.2 DIMM Module Replacement Procedure

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 you
may skip this section.
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:
Step 1. Remove the controller module. (See Section 5.2.3.)
Step 2. Remove the previously installed DIMM module from the
5-6
NOTE:
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 5-6)
