Maintenance mode restricts access to CC-SG so that an administrator can perform operations without disruption. Some examples of operations that are best performed in maintenance mode include changing the inactivity timer or backing up CC-SG. This ensures that system wide settings, such as the inactivity timer, will be changed for all users.
Current users, except the administrator who is initiating Maintenance Mode, are alerted and logged out after the configurable time period expires. While in Maintenance Mode, other administrators are allowed to log into CC-SG, but non-administrators are prevented from logging in. An SNMP trap is generated each time CC-SG enters or exits Maintenance Mode.
Note 1: Maintenance Mode is available only on standalone CC-SG units that are not in cluster configurations.
Note 2: Upgrade CC-SG is disabled until you enter Maintenance Mode.
