2 GETTING STARTED / 2.4 System Structure
Hot Standby Function
The Switchover function with the Active state is supported by preparing a Main Repeater and a Sub Repeater. Switchover
is the function to switch a Main Repeater and a Sub Repeater.
Also, the status of the role of each repeater can be confirmed on the Web Tool.
Configuration Item
Hot Standby
Failsoft Mode
Auto Active Status Switch
Virtual IP Address
Both a Main Repeater and Sub Repeater always check each other's PIP (Physical IP Address). After the
synchronization state is established, if VIP (Virtual IP Address) is enabled on either repeater, the repeater enters the
Active state. The repeater for which VIP is not enabled migrates to the Standby state.
After starting, if the synchronization status cannot be established even once within the duration of Failsoft Mode Wait
Timer, the Main Repeater migrates to Failsoft Mode and the Sub Repeater enters the Active state. After
synchronization, if the repeater in the Active state continues to be out of synchronization with the repeater in the
Standby state within the duration of Failsoft Mode Wait Timer, the repeater in the Active state also migrates to Failsoft
Mode. If the repeater in the Standby state cannot synchronize with the repeater in the Active state, the repeater
in Standby state migrates to the Active state.
If the synchronized Main Repeater and Sub Repeater continue to be out of synchronization for the duration of Failsoft
Mode Wait Timer, the repeater in the Active state forcibly restarts with Hot Standby disabled. This status is called
Failsoft Mode, and the radio behavior can be continued as a Single site in the event of the failure of the repeater in
the Standby state, etc. VIP is not enabled at this time. E102 (Hot Standby LAN Connection Error) is displayed during
Failsoft Mode.

Table 2-10 Configuration Items of Hot Standby
Description
The Hot Standby function and the role of the Hot Standby function can be
configured.
The conditions to migrate to Failsoft Mode can be configured.
The time and interval for automatically switching the Active status can be
configured.
By sharing the same IP address in Hot Standby pairs, the impact on other sites
and consoles when the Active status is switched can be minimized.
