2.6.Memory Module Installation

2.6.1Memory Module Installation Overview

The subsystem comes with a pre-installed 512MB 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 compatibility problems.

Considerations:

1.A DIMM socket is located on the side of the controller main 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 BBU module is removed before replacing the DIMM module. The BBU can be removed simply by loosening its retention 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.
