EonStor GSa 3000 Series Hardware Manual
1.4.4 Super capacitor and flash backup module
The GSa 3000 Series system also has a CBM (Cache Backup Module), which is comprised of a super
capacitor (1) and flash backup module (2), installed in the controller. The super capacitor provides power
for the system to store cached data to the flash backup module in case of power interruption or outage.
NOTE:
The super capacitor is partially charged when shipped. When you turn ON the system, the super
capacitor will charge to its full capacity for a few minutes. If it is not charging, there may be a problem.
Contact your system vendor immediately. You can also check the status of the super capacitor via
EonOne or the firmware. Refer to the manuals for more details.
NOTES:
•
The PSU/cooling modules have specific installation orientations for left and right slots. Refer to the
label at the back of the system.
•
There are two upper temperature thresholds: one for event notification and the other for triggering
high fan rotation speed. You can change the preset values for event notification using the firmware-
embedded configuration utility. Refer to the firmware operation manual for details.
WARNING!
• If any of the LEDs lights up in red, contact your local vendor to request for a replacement
immediately.
•
When removing the PSU/cooling module, pull the module for about 3 inches then wait for at least 10
seconds before removing the whole module from the enclosure.
•
DO NOT run the system with faulty PSU/cooling module(s) as it may cause disruption of the airflow
resulting in overheating.
CAUTION!
Keep your body away from the moving parts of the system.
