Network Management Card
44
Schedule a synchronized shutdown. All scheduled shutdowns will be synchronized
when the UPS whose Management Card initiates the shutdown is a member of a
Synchronized Control Group and its status as a group member is enabled. Always
schedule all shutdowns through the same member of the group. For a scheduled
synchronized UPS shutdown to occur, a network connection to each UPS in the group
must exist at the time at which the action is scheduled to occur.
Edit, Enable, Disable, or Delete a Scheduled Shutdown. To access and edit the
parameters of a scheduled shutdown, disable it temporarily, or delete it permanently,
click the shutdown name in the list of shutdowns, and follow the on-screen instructions.
The Sync Control Option
Guidelines for Synchronized Control Groups
Before you configure this UPS as a Synchronized Control Group member, review these
guidelines:
• All UPSs in a Synchronized Control Group must be the same model.
• Synchronized Control Groups are supported for any Smart-UPS or Symmetra UPS
with a card slot that accepts a Network Management Card.
• In a Synchronized Control Group of Symmetra 3-phase UPSs, the shutdown mode
setting configured at the UPS must be the same (either Normal or Secure) for all
group members.
• When its membership in a Synchronized Control Group is enabled, the Management
Card blocks UPS communications from a connected APC management device on
the serial communications port. However, the Management Card still allows access
to the control console on the serial communications port.
Caution
Do not schedule shutdowns through more than one group member. Such
scheduling may cause unpredictable results.
