6.7 Battery Backup
The UNIVERGE SV9100 system has battery backup functions for system backup
and for memory backup.
6.7.1 System Backup (Optional)
During a power failure, the CHS2UG can be backed up using the CHS2UG
BATT MTG KIT for a backup time of 10 minutes or one of the CHSG
LARGE BATT SETs for a backup time ranging from 45~180 minutes. The
CHS2UG GW can be backed up using the CHS2UG B SMALL BATT BOX
for a backup time of 10 minutes.
6.7.2 Memory Backup
The GCD-CP10 Blade battery retains the Clock/Calender and Last Number
Redial (LNR) buffers for each station when the GCD-CP10 Blade
encounters a power loss. With a fully charged battery, the settings are
retained for about three years. The System Programmed memory
(Customer Database) is stored in non-volatile Memory and can be erased
only by a First Initialization. After power is restored, the system Blade
returns to normal operation.
