4.1.3 Replacing the Memory Module
The controller comes with a pre-installed DRAM module(s). You can upgrade or replace it when the
bundled module malfunctions.
IMPORTANT!
• We strongly recommend you to NOT use the removed DRAM module from a failed controller of a
different storage system.
• Contact your system vendor to help you purchase the compatible DRAM modules.
• When removing/installing a memory module in a single-controller system, ensure that you shut
down the applications and the system.
NOTE: Refer to section ESD Precautions for safety information.
To replace the memory module:
1. Remove the controller that contains the memory module you want to replace.
NOTE: See section 4.1.2 Replacing the Controller Module for details.
2. Look for the DIMM slots in the controller.
