To support the deployment and maintenance of many Session Manager or Branch Session Manager instances, you can set the non-operational Session Manager or Branch Session Manager to the Maintenance Mode service state. The Maintenance Mode service state places Session Manager or Branch Session Manager into a dormant state. Maintenance Mode is not a SIP service state and is independent of the Deny and Accept New Service states.

Use the Maintenance Mode service state for:

• Staging installations where Session Manager or Branch Session Manager is not provisioned on the network.

• Pre-administering a large number of Branch Session Manager instances before installing or configuring the machines.

• Upgrading an existing Session Manager or Branch Session Manager.

• Preventing large amounts of error logging and alarming during a temporary outage.

When you change the service state to Maintenance Mode, the system:

• Changes the service state of Session Manager or Branch Session Manager to the Deny New Service state from Accept New Service.

• Does not generate alarms.

You can change the service state to Maintenance Mode by using the Session Manager Administration page or the Session Manager dashboard. Maintenance Mode is an option on the Service State menu.

When you add a new Session Manager or Branch Session Manager instance, the Maintenance Mode option is enabled by default.
