Step 7. Power up the subsystem.
5.3 Replacing or Upgrading Memory Modules
5.3.1 Memory Module Installation Overview
ƒ
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.
ƒ
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 SS16i controller module is going to be replaced, the following
factors must be considered when purchasing replacement DIMM modules:
ƒ
Purchasing a DIMM module: To avoid the compatibility issues, it is
recommended to contact EMD for an updated list of compatible DIMM
modules. We provide tested modules from reliable vendors with reliable chips.
ƒ
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.
ƒ
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.
ƒ
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.
