2.6. Memory Module Installation
2.6.1 Memory Module Installation Overview
The subsystem comes with a pre-installed 256MB DDR RAM DIMM module on each
controller. The controller supports memory modules with sizes up to 2GB. If memory
modules with a different size need to be used, the pre-installed DIMM module can be
removed and the new ones installed. Replacement and installation instructions are
described fully below.
NOTE:
A DIMM of a different size can be ordered from your subsystem supplier. Using non-
certified modules can cause unexpected results.
Considerations:
1. The DIMM module is located on the side of the main controller board. Prior to
changing the DIMM module, the controller canister must first be removed from the
enclosure chassis.
2. With a new subsystem, there may not be cached data in the DIMM module. If the
subsystem has been operating and there is cached data, the BBU will discharge to
support the cache contents. It is therefore recommended to make sure there is no
BBU module installed before replacing the DIMM module. The BBU module is
located right above the controller’s rear-facing faceplate and can be removed simply
by loosening its retention spring screw.
If you are replacing the memory modules, please refer to the installation procedure
below. If the memory modules do not need to be changed, proceed to Section 2.7.
