Chapter 5: Subsystem Maintenance and Upgrading
Replacing or Upgrading Memory Modules
5-7
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!
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.
5.3.2 Selecting the Memory Modules
If the memory module on the GHDX2-2130-16-iSCSI controller module is going to be
replaced, the following factors must be considered when purchasing replacement DIMM
modules:
Purchasing a DIMM module:
To avoid the compatibility issues, it is
recommended to contact Rorke or your subsystem vendor for an updated list of
compatible DIMM modules. We provide tested modules from reliable vendors
with reliable chips.
DDR RAM DIMM modules supported
: The subsystem supports 184-pin,
registered, ECC-capable DDR RAM DIMM modules with memory capacities
ranging from 512MB to 2GB.
Installation considerations:
When installing the DIMM module, it is necessary
to remove the controller module. The controller board is more susceptible to
damage than other components and must therefore be handled with extreme
care. ALL anti-static precautions specified in
Section 2.3
must be strictly
adhered to.
Secure installation
: When replacing the DIMM module, make sure that the new
DIMM module is firmly in place prior to installing the controller module. If the
DIMM module is not firmly in place, the subsystem will not run and the
controller will need to be removed and the DIMM module correctly installed.
5.3.3 DIMM
Module
Installation
WARNING!
The pre-installed modules must be removed prior to installing new modules. Do this
with care. Sensitive components can be damaged during the process.
