CAUTION!
The controller board in the module contains sensitive components. Please ensure that all anti-
static precautions stipulated above are strictly adhered to. Only qualified technicians can
replace a DIMM module.
6.3.2
Selecting a Memory Module
If the memory module mounted on the controller is going to be replaced, the following factors
should be considered when purchasing replacement modules.

Remove the failed controller module.
Install a DIMM module on the new controller module.
Insert the replacement controller. Align the controller module with the module bay at the
rear of the subsystem. Gently slide the controller module in.
Fasten the hand screws. Once the controller module has been completely inserted into
the subsystem chassis, secure the controller module to the chassis by tightening the
hand screws at the sides of the controller rear panel.
Connect the controller module cables: Reconnect all of the cables that were previously
disconnected from the controller module. These may include SCSI cables for host and
expansion connections, an RS-232C (audio jack) cable for serial port connection, and an
Ethernet cable for network connection.
Power on: Once the new controller module has been properly installed and the cables
have been correctly connected, turn the subsystem power on.
The subsystems come with a pre-installed 256MB (or above) DDR RAM DIMM module on
the controller. The controller supports one memory module for the capacity up to 1GB. If
a DDR RAM DIMM modules with a different size is preferred or the original memory mod-
ule has failed in some way, the pre-installed module must be removed and replaced by a
new one. Replacement and installation instructions are described fully below.
The DIMM module is located on the controller board. The controller board is a sensitive
component and must be treated with care to avoid being damaged.
Pre-installed DIMM module: The subsystem comes with a 256MB DDR RAM module pre-
installed on the controller board. If you wish to change the size of the DIMM, then a new,
separately purchased DIMM can be installed.
DDR RAM DIMM modules supported. The subsystems support DDR RAM DIMM modules
with the capacities ranging from 256MB to 1GB.
Installation consideration: When installing the DIMM module, it is necessary to handle the
controller module. The controller board is more susceptible to damage than the other
components and must therefore be handled with extreme care. All anti-static precautions
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.
Purchasing consideration: When purchasing a DDR RAM DIMM to install on the controller
board, contact your vendor for an updated list of certified modules.
