Load Shedding Mode
When a UPS supplying power to the PX3 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. To set
non-critical ones, see
Setting Non-Critical Outlets
(on page 180).
When load shedding is activated, the PX3 turns off all non-critical outlets.
When load shedding is deactivated, the PX3 turns back on all non-critical
outlets that were ON before entering 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.
Note: It is highly suggested to check non-critical outlets prior to
manually entering the load shedding mode. The non-critical information
can be retrieved from the Outlets page. See
Outlets
(on page 173) or
Available Data of the Outlets Overview Page (on page 176).
