Galaxy GHDX2-2430S/R-24F4D Installation and Hardware Reference Manual
5-4 Subsystem Maintenance
BBU Module The BBU can be installed after the initial
installation procedure or replaced if a previously
installed BBU module is faulty or fails to hold its
charge.
Main Board If the controller module in a single controller
model fails, it is necessary to power the system
down and replace the controller.
5.2.2 Notes on Controller Module Maintenance
ƒ
The 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.
ƒ
When 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.
5.2.3 Removing 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.
