5.3.4 Hot Standby
Redundancy is achieved by using duplicate hardware and software installations
and synchronizing data and operating state. Redundancy assures smooth
operation even if a system goes down. Essentially a duplicate backup system
takes over with virtual no loss of service. This technique assures absolute
reliability no matter what failure occurs. In mission critical installations,
redundancy is a way to address possibility of any failure.
Note 1: Before enabling the Host Standby feature, please make sure that the
two servers in the failover pair are the same model, have the same modules
installed in the same slots, the same hardware configurations and firmware
version.
Note 2: Please configure the primary server first and configure the secondary
server only after the running status of primary server becomes “active”.
Note 3: The virtual IP address inputted in this page will be the one used for
registering in each IP phone.
Note 4: Before configure the Email list in this page, please configure the
‘voicemail settings’ in “PBXBasic settings”, make sure the SMTP testing
successfully.
