5.5 Battery Backup
The UNIVERGE SV8100 system has battery backup functions for system
backup and for memory backup.
5.5.1 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 can be backed up using the CHSGW
SMALL BATT BOX for a backup time of 10 minutes.
5.5.2 Memory Backup
The CD-CP00 blade battery retains the Clock/Calender and Last
Number redial (LNR) buffers for each station when the CD-CP00
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.
