EonStor S12E-R1132-4/G1133-2 Installation and Hardware Reference Manual
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.

Replacing or Upgrading Memory Modules
5.3.1
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
