Maintenance Mode
This mode restricts access to CC-SG so that an administrator can perform various operations
without disruption. Operations can be performed from the GUI or from an SSH command line
interface via clients, such as Putty, OpenSSH Client, etc. Please refer to Chapter 12: Advanced
Administration, SSH Access for additional information.
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: Maintenance Mode is only available on standalone CC-SG units and not in a cluster
configuration. Upgrade CC-SG is disabled until you enter Maintenance Mode.
Scheduled Tasks and Maintenance Mode
Scheduled tasks cannot execute while CC-SG is in Maintenance Mode. Please refer Chapter 12:
Advanced Administration, Task Manager for additional information on scheduled tasks. When
CC-SG exits Maintenance Mode, scheduled tasks will be executed as soon as possible.
