HA
Dual-system hot standby provides a highly reliable and fault-tolerant solution for enterprises using UCM6300
series/UCM6300A series. Based on two UCM devices of the same product model and software version, one of them
is in the "Active" working state in real time, and the other is in the "Standby" working state. The daily data on the host
server will be synchronized to the standby machine in real time, and the standby machine monitors the running status
of the host at all times. When the host fails, including hardware failures and severe software failures, the standby
machine will immediately take over the business and enter the "Active" working state, and Upgrade to a host to ensure
that the business is not interrupted, and the call will automatically resume.
Before forming a paired HA dual-system hot backup, two UCM devices need to complete their respective network
settings. The network mode can only be switching or routing, and the IP type can only be static.
