Scenario 2: 1 UCM is configured and running, and the 2
nd
UCM needs to be added for HA
setup. Both UCM use UCMRC service.
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. Since UCM A is already configured and running, choose this UCM as the active UCM.
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 Settings→HA 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.
5. Verify HA status on UCM A. Log in UCM A using its static IP and admin login information. On web
UI→System Settings→HA page, ensure HA function is enabled. HA status should display “Active”.
6. After ensuring UCM A’s HA status as active, now configure UCM B as secondary UCM and
complete the HA settings. Log in UCM B’s web UI and go to System Settings→HA page, enable
HA and set the station type as “Secondary”. Please refer to HA related parameters in table 2 below
to complete other HA related settings. Save the settings and reboot UCM B.
7. Verify UCM B’s HA status. UCM B boots up normally, log in UCM B’s web UI via the static IP
address and admin login information. Go to System Settings→HA page, ensure the HA function is
enabled, “Switch” button is grey and only HA peer IP/HA MAC address buttons are available for
configuration.
8. Purchase UCMRC plan for both UCM. If UCM A already has UCMRC plan, then purchase UCMRC
for UCM B only. Log in UCM web UI and go to Value-added Features→UCM
RemoteConnect→Plan page, click on “Learn More”. Then follow the page to add the UCM to GDMS
and assign UCMRC plan. It doesn’t matter which UCM is assigned with UCMRC plan first.
9. For UCM A which has station type “Primary”, configure custom domain name. Please refer to
custom domain name configuration section below. If UCM A already has custom domain name, this
step can be skipped.
Note: For UCMRC related settings, please refer to section “UCMRC Configurations”.
