DIMM Module Replacement
The subsystem comes with a pre-installed 512MB capacity or above DDR
RAM DIMM module on each controller. The controller supports memory
up to 2GB DDR RAM DIMM. If a memory module fails a different size of
DIMM module is preferred, the pre-installed module can be removed and
the new one installed. Replacement and installation instructions are
described fully below.
NOTE:
If you are going to replace or upgrade a DIMM module, please follow the
instructions below. If you do not want to replace or upgrade a DIMM you
may skip this section.
5.3.1
DIMM Module Considerations
If the memory module on the controller module is going to be replaced, the
following issues must be considered when purchasing a replacement DIMM
module:
Purchasing considerations:
When purchasing a DDR RAM
DIMM module to install on the F16F subsystem’s controller board,
contact your subsystem vendor for an updated list of compatible
DIMM modules.
IMPORTANT!
The DIMM modules applied in a dual-controller configuration, F16F-
R4031, must have the exactly SAME SIZE and SPEED.
DDR RAM DIMM modules supported:
The RAID controllers in
F16F subsystems support DDR RAM DIMM module with memory
capacities ranging from 512MB to 2GB.
Installation considerations:
When installing the DIMM module, it
is necessary to remove the controller module from the chassis and
disperse the module. The controller board is more susceptible to
damage than the other components and must be handled with
extreme care.
Secure installation:
When replacing the DIMM module(s), make
sure that the new DIMM module(s) are firmly in place prior to re-
installing the controller module(s). If the DIMM module(s) are not
firmly in place, the subsystem will not be able to run and the whole
procedure must be repeated.
