ACKUP
The UNIVERGE SV8100 system has battery backup functions for system backup and
for memory backup.
7.1 System Backup (Optional)
During a power failure, the system can be backed up using the CHS2U BATT
MTG KIT for a backup time of 10 minutes or one of the CHS LARGE BATT
SETs for a backup time ranging from 45~180 minutes. The CHS2U GW-US
can be backed up using the CHSGW SMALL BATT BOX for a backup time of
10 minutes.
7.2 Memory Backup
The CD-CP00-US blade battery retains the Clock/Calender and Last Number
redial (LNR) buffers for each station when the CD-CP00-US 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 nonvolatile Memory and can be erased only by a First Initialization.
After power is restored, the system blade returns to normal operation.
