Load Shedding Mode: Activate Or Deactivate - LEGRAND Server Technology PRO4X User Manual

Load Shedding Mode: Activate or Deactivate

Load Shedding is not supported on all models
When a UPS supplying power to PRO4X switches into battery backup operation, it may be desirable to
switch off non-critical outlets to conserve UPS battery life. This feature is known as load shedding.
Outlets that are turned off when load shedding is activated are called non-critical outlets. Outlets that
are not affected by load shedding are called critical outlets. By default, all outlets are critical.
When load shedding is activated, the PRO4X turns off all non-critical outlets. When load shedding is
deactivated, the PRO4X turns back on all non-critical outlets that were ON before entering the load
shedding mode.
Exception: If you once manually perform switch-off operation on any non-critical outlets during the load
shedding mode, those outlets will NOT be turned back on when exiting the load shedding mode.
Activation of load shedding can be accomplished using the web interface, SNMP or CLI, or triggered by
the contact closure sensors.
Tip: It is better to check non-critical outlets prior to manually entering the load shedding mode. The
non-critical information can be retrieved from the Outlets page.
You must have one of the following permissions to perform the load shedding commands.
• •
'Change Pdu, Inlet, Outlet & Overcurrent Protector Configuration'
• •
'Switch Outlet' permission for all non-critical outlets
• •
Administrative privileges
