surviving controller supports the “
≥
1GB” defaults.
NOTE
: If the firmware screen shows 16 indexes, you may
refer to the Case 2 procedure if you prefer enlarging the
number of logical configurations.
3-2.
Install a 1G or 2G memory (size identical to that on the
surviving controller) to the replacement controller.
3-3.
Restore the replacement’s defaults using the Restore
Default button or the LCD keypad panel. (See Appendices
for details) You should use another RAID system to
restore the defaults on the replacement controller.
3-4.
Replace the failed controller with the replacement. The
replacement should be brought online after a short while.
5.3.2
Selecting the Memory Modules
If the memory module on the 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.
