HA CONFIGURATIONS
For UCM without UCMRC Plan
For two new UCM on factory default setting, system admin can choose to configure any of them for HA first.
However, if one of the UCM is already configured, up and running for PBX service, system admin should
configure this UCM as HA Primary server and complete all HA settings on it first so it can act as active role.
Assuming no UCMRC (Remote Connect) service is used on any UCM, please refer to the steps below to
configure HA on UCM:
1. Ensure both UCM have the same model and same firmware version. They have been connected
properly at the same location and configured with static IP.
2. Select one UCM to be the active device (UCM A). If both UCM are new on factory default settings,
select any of them as the active UCM. If one of the UCM is already configured and running, then
select this UCM as the active device.
3. If Cloud IM service is needed, please enable Cloud IM on UCM A (active UCM) and ensure Cloud
IM is disabled on the other UCM (UCM B).
4. Log in the active UCM (UCM A) web UI and go to System SettingsāHA page. Enable HA and
configure UCM A as Primary station type. Please refer to HA related parameters in table 2 below
and complete other HA related settings. Save the HA settings on UCM A and reboot UCM A. Ensure
UCM A boots up normally.
