Replacing the CBM (Cache Backup Module) components
The CBM is comprised of a super capacitor and the FBM (flash backup module). The super capacitor
allows your controller to provide more power during a power outage, supporting the controller to save
the data to the FBM.
WARNING! Ensure that you have the replacement on hand before replacing your current CBM.
Super capacitor fault conditions and precautions
If a super capacitor leaks, gives off bad odor, generates heat, becomes discolored or deformed, or
appears abnormal when charging or storing, remove it from the system immediately. These issues may
be due to the following:
•
The temperature sensor on the system's charger circuit reports the temperature that exceeds the
preset threshold. The charger circuit enters to a low power and self-protection state.
•
A super capacitor module has been charged for more than 10 minutes. When this occurs, the
charger enters a timer fault state. Charging resumes automatically after you remove or reinstall the
super capacitor, or after you reset the system.
When reinstalling/replacing the super capacitor, remember these precautions:
•
ONLY use a replacement super capacitor supplied by an authorized distributor. Use of other
capacitors voids your system's warranty.
•
ONLY dispose your used/defective super capacitor at an authorized battery disposal sites.
•
DO NOT place the super capacitor near a heat source.
•
DO NOT immerse/submerge the super capacitor in water or other liquids.
•
DO NOT disassemble or modify the super capacitor.
•
DO NOT pierce, strike, throw, or exert pressure on the super capacitor.
