Chapter 5 Subsystem Maintenance and Upgrading
5.2.2 Notes on Controller Module Maintenance
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.
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
WARNING!
1.
Consult with your reseller s or distributor s technical support
department to confirm which memory module can be installed into the
controller module.
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 will
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.
Step 2.
If working on the dual-controller FALCON-R2224, the
workload should have been taken over by the surviving RAID
controller.
Step 3.
Remove the BBU module if one has been installed. Loosen the
BBU module’s spring screw and then simply retrieve it from the
chassis.
