6.3	Replacing or Upgrading Memory Modules
6.3.1	Memory Module Installation Overview

•

•

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.

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.
	• 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.
6.3.3	DIMM Module Installation
	CAUTION!
	The pre-installed modules must be removed prior to installing new memory modules. Do this
	with care. Sensitive components can be damaged during the process.

If a DIMM module fails or a DIMM module with a higher memory capacity is required, the DIMM module must be replaced.

1.Remove the controller module.

2.Remove the previously installed DIMM module from the DIMM socket. To do this, push the white module clips on the sides of the DIMM module down together. By doing this, the previously installed modules will be ejected from the DIMM socket. (See Figure 6.2)
