Super Capacitor and Flash Backup Module
PS 4000 Gen2 Series system has a CBM (Cache Backup Module), which is comprised of a super
capacitor and flash backup module, installed in the controller. The super capacitor provides power,
allowing the system to store cached data to the flash backup module permanently in case of power
interruption or outage.
NOTES:
• 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 the PAC Management Software or the firmware. Refer to the manuals for
more details.
• The flash backup module is located under the super capacitor.
