CHAPTER 7: Alarm Configuration

7.2.1.Over Temperature Alarms - Load Shedding and Auto Recovery

For Over Temperature Alarms, the Load Shedding feature is used to switch specific, user-defined plugs On or Off whenever temperature exceeds the Alarm Set Threshold value. This allows the Outlet Managed PDU to automatically shut Off non- essential devices in order to reduce the temperature generated within the rack, or automatically switch On devices such as fans or cooling systems in order to dissipate heat. When the Auto Recovery feature is enabled, the Outlet Managed PDU can also automatically "undo" the effects of the Load Shedding feature when the temperature again falls to a user-defined non-critical level.

Note:

Load Shedding Configuration Menus for both the Initial and Critical Over Temperature Alarms offer essentially the same set of parameters, but parameters defined for each alarm are separate and unique. For example, parameters defined for Over Temperature (Initial) Alarm Load Shedding will not be applied to Over Temperature (Critical) Alarm Load Shedding and vice versa.

The Load Shedding Configuration menus allow you to defined the following parameters:

Unit to Configure: In some compatible power control products, this item is used to select either a local unit or an auxiliary unit. In Outlet Managed PDU series products, this option has no function. (Default = Local.)

Enable: Enables/Disables Load Shedding for the Over Temperature Alarm. When enabled, the Outlet Managed PDU will switch the user specified plugs whenever the temperature exceeds the Alarm Set Threshold value.

(Default = Disable.)

Plug State: Determines whether the selected plugs/plug groups will be switched On or Off when Load Shedding is enabled and temperature exceeds the user-defined Alarm Set Threshold. For example, if the Plug State is set to "Off", then the selected plugs/plug groups will be switched Off when the Alarm Set Threshold is exceeded. (Default = Off.)
