WJ-ND400 Backup System
When an ASC970 System includes both Main WJ-ND400 and Backup WJ-ND400, it is called the WJ-ND400
Backup System. When the ASC970 Server detects that Main WJ-ND400 becomes offline or their all hard disk
drives become failure, the ASC970 Server transfer the latest configuration data of Main WJ-ND400 to Backup
WJ-ND400. And then the ASC970 Server can control the Backup WJ-ND400.
