Memory Module Installation Overview

․
The subsystem comes with a pre-installed 512MB (or above)
DDR RAM DIMM module. The controller supports a memory
module up to 2GB in size. If DDR RAM DIMM modules with a
different size need to be used or the original memory module is
damaged in some way, the pre-installed module can be
removed and a replacement installed. Replacement and
installation instructions are described fully below.
․
A DIMM socket is located on the controller main circuit board.
The controller board is a sensitive component and must be
treated with care.
WARNING!
1. The controller board in the controller module is a sensitive item.
Please ensure that all anti-static precautions stipulated above are
strictly adhered to. Only qualified engineers should replace the
DIMM module.
2. There is a "1GB" parameter threshold for NVRAM defaults in
Infortrend's disk array firmware. The 1GB threshold determines
whether your RAID supports a standard or a large number of
logical configurations by the size of cache memory.
The supported numbers by different DIMM sizes are shown below:
5-8
WARNING!
Unnecessary tampering with the controller module can
cause damage. Remove the controller ONLY when it is
absolutely necessary.
When you remove a controller module from the chassis, all
anti-static preventative measures should be strictly adhered
to. Failure to adhere to specified cautionary measures could
result in damage to the controller board.
