6.3	DIMM Module Replacement
	The subsystem comes with a pre-installed 256MB capacity or above DDR RAM DIMM module
	on the controller. The controller supports memory up to 1GB. If a DDR RAM DIMM module has
	failed or a different size of DIMM module needs to be used, the pre-installed module must be
	removed and the new one installed. Replacement and installation instructions are described
	fully below.
6.3.1	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:
	• Pre-installed DDR RAM DIMM module: The RAID subsystem comes with a 256MB capacity
	or above DDR RAM DIMM pre-installed on the controller board and can support up to
	1GB capacity. If you wish to change the size of the DDR DIMM, then a new DIMM must be
	installed.
	• Purchasing considerations: When purchasing a DDR RAM DIMM module to install on the
	RAID subsystem controller board, contact your subsystem vendor for an updated list of
	compatible DIMM modules.
	• DDR RAM DIMM module supported: The RAID subsystem supports DDR RAM DIMM mod-
	ules with memory capacities between 256MB and 1GB.
	• Installation considerations: When installing the DDR RAM DIMM module, it is necessary to
	remove the controller 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, make sure that the new DIMM
	module is firmly in place prior to re-installing the controller module. If the DIMM module
	is not firmly in place, the subsystem will not run and the whole procedure must be
	repeated.

NOTICE!

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 module and would like to install a controller module, please go to Section 6.2.3 Replacing the Controller Module.

If a DIMM module fails or if a DIMM module with a higher memory capacity is required, the onboard DIMM module must be replaced. To replace the DIMM module:

1.Remove the controller module. (See Section 6.2.2 Removing the Controller Module)

2.Remove the previously installed DIMM module from the DIMM socket. Pull down the white clips on either side of the DIMM module to a 45-degree angle to dislodge the DIMM module. (See Figure 6.6)
