Chapter 5: Subsystem Maintenance and Upgrading
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!
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 A16E-G2130-4 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 Infortrend 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.
