SERVICE STATUS

Active/Standby Status

After HA setup is completed, the PBX will provide service using the HA cluster IP. During initial stage,
standby UCM will request and synchronize up all data from the active UCM.
The standby UCM monitors and prepares to become active at any time when needed. Manual configuration
on standby UCM is restricted because it always synchronizes up data from active UCM. When the active
UCM has any hardware or critical software failure, the standby UCM will immediately take over and
becomes the active UCM. The previous active UCM will reboot and become the standby UCM. Calls during
the role switchover will be recovered after failover process completes.

Web UI Access for UCM

After HA setup is completed, the system admin can use the cluster IP address to log in the current active
UCM for configurations. The cluster IP address is always bind to the active UCM. For example, assuming
HTTP/HTTPS port is 8089, system admin can access UCM using URL https://cluster_IP:8089.
If the system admin logs in the standby UCM's web UI by using the standby UCM IP and attempts to modify
configurations, it will not be allowed. The system will prompt that configuration is restricted on the standby
UCM.
Note: HA setup will synchronize up admin login information from the active UCM to the standby UCM.
Therefore, when system admin logs in the UCM web UI using the active UCM IP, standby UCM IP or the
cluster IP, the active UCM's login information always needs to be used.

Log in Wave

After HA configuration, the login URL for Wave may be changed. Users can log in Wave using the following
addresses:
1. Log in via IP.
Since the UCM providing RemoteConnect service can be the primary or secondary UCM, user should
always use the cluster IP to log in Wave. For example, https://cluster_IP:8089/gswave#.
2. Log in via domain name.
No matter whether failover happens, users could always use the domain name assigned from GDMS
Remote Connect service, which is determined by the initially configured primary UCM.
