Configure Hot Standby
Before configuring hot standby, you need to finish the following tasks:
• Ensure that the two MCU devices which can be treated as standby
machines for each other have the same software version and model.
• Configure the two MCU devices within the same network segment,
which can be treated as standby machines for each other.
• Confirm the master-slave relationship among the two MCU devices. It is
recommended that you back up the configurations and address books on
the master MCU system to your local computer so that they can be used
to restore the relevant data when the data on the master device cannot be
correctly synchronized to the slave device.
• With hot standby, you cannot register your SIP server. Please ensure that
your MCU system is not registered.
• Hot Standby allows you to enable only one network port. Please ensure
that the two MCU devices which can be treated as standby machines for
each other have only one LAN port enabled.
Configure the master/slave machine:
When hot standby is configured, the device started first will become a master
device and the other one will become a slave device, so you need to configure the
MCU that will be used as a master device first.
1 In the device list area, double-click Single Machine Mode.
2 In the Work Mode Settings dialog box, select Hot Standby.
3 In IP Address for Standby Machine, enter the IP address for another MCU
device which can be treated as a standby machine.
4 Enter the IP address for the services, which must be set within the same
network segment as the MCU address. The two MCU devices will use this
IP address to provide outward services, and an endpoint must also use
this IP address to dial into the system.
