4.1.4 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!
• If your controller has two modules, you must identify the correct module that is no longer working
before you proceed with the replacement.
• 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.
NOTE: Refer to section ESD precautions for safety information.
To replace the memory module:
1. Shut down your system, unplug the power cords, then remove the controller. Wait for a minute for
the remaining electric current to dissipate.
NOTE: See section 4.1.3 Replacing the controller module for details.
2. Look for the DIMM slots in the controller.
