5.2.2Notes on Controller Module Maintenance

ƒThe controller module contains a DIMM module and a BBU module. When replacing the controller module, these components can be removed and used on the new controller module if they are functioning normally.

ƒWhen replacing the controller module, you must remember that the controller board is one of the most sensitive components in the subsystem. All previously stipulated safety precautions (see Chapter 2) must be strictly adhered to. Failure to adhere to these precautions can result in permanent damage to the controller board, resulting in timely delays.

5.2.3Removing the Controller Module

CAUTION!

1.It is recommended to apply Galaxy certified memory modules to avoid compatibility issues.

2.The installed BBU and controller module must be removed prior to installing new memory modules. Do this with care. Sensitive components can be damaged during the process.

3.The BBU is hot swappable and can be independently swapped from the controller. However, as a safety precaution and in case your memory still holds cached data, it is recommended to remove the BBU before handling the DDR RAM module. If the BBU is supplying power to the memory when the DDR module is being removed, damage may occur!

To remove the controller module:

Step 1. Prepare a clean, static-free work pad on which to place the controller that will be removed from the chassis.
