How to schedule a synchronized shutdown
To use the Network Management Card’s Web interface to schedule
shutdowns within a Synchronized Control Group, always schedule all
shutdowns through the same member of the group.
The following guidelines apply to Synchronized Control Groups:
• All UPSs in a Synchronized Control Group must be the same model.
• Synchronized Control Groups are supported for most UPS models of
the Smart-UPS and Symmetra UPS product lines. Any Smart-UPS or
Symmetra UPS with a card slot that accepts a Network Management
Card supports Synchronized Control Groups.
• In a Synchronized Control Group of Symmetra 3-phase UPSs, the
shutdown mode setting must be either normal or secure for each UPS.
All scheduled shutdowns will be synchronized when the Network
Management Card that initiates the shutdown is a member of a
Synchronized Control Group and its status as a group member is enabled.
Caution
Scheduled shutdowns through more than one group member
is not a supported configuration and may cause
unpredictable results.
