Setting Non-Critical Outlets and Load Shedding Mode
This section only applies to outlet-switching capable PDUs.
When a UPS supplying power to the PDU 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.
Activation of load shedding can be accomplished using the web interface,
SNMP or CLI, or triggered by the contact closure sensors.
Outlets that are turned off when load shedding is activated are called
non-critical. Outlets that are not affected by load shedding are called
critical outlets. When load shedding is deactivated, the PDU will turn back
on all non-critical outlets. By default, all outlets are configured as critical
until you configure them otherwise.
Marking All Outlets
This section only applies to outlet-switching capable PDUs.
You can configure all critical and non-critical outlets at a time.
To mark all outlets at a time:
1. Click the PDU folder.
Note: The PDU folder is named "my PX" by default. The name
changes after customizing the device name. See
Naming the PDU
(on page 83).
2. Click Setup Non-Critical Outlets in the Load Shedding section. The
"Non-critical Outlet Setup" dialog appears.
Tip: This dialog can be also triggered by clicking the "Non-critical
Outlet Setup" button on the Outlets page when selecting the Outlets
folder.
