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.

5.3.3DIMM 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.
