CHAPTER 7: Alarm Configuration

The Load Shedding feature can be configured to react in one manner when an Over Current Line Alarm is triggered, and in a different manner when an Over Current Branch Alarm is triggered. For example, Load Shedding may be configured in such a way that when the Line Alarm is triggered, plugs A1 and B1 are switched Off, but when a Branch Alarm is triggered, plugs A1 and A2 are switched Off.

Notes:

In order for the Outlet Managed PDU to provide alarm notification via Email, communication parameters must first be defined as described in Section 5.9.11.

In order for the Outlet Managed PDU to provide alarm notification via Syslog Message, Syslog parameters must first be defined and Syslog Messages must be enabled as described in Section 5.9.2 and Section 11.

In order for the Outlet Managed PDU to provide alarm notification via SNMP Trap, SNMP parameters must first be defined, and SNMP Traps must be enabled as described in Section 5.9.7 and Section 12.

To configure the Over Current Alarms, access the Outlet Managed PDU command mode using a password that permits Administrator Level commands, and then use the Alarm Configuration menu to select the desired alarm feature.

Note that the configuration menus for both Over Current Alarms offer essentially the same set of parameters, but the parameters defined for each alarm are separate. Therefore, parameters defined for a Critical Alarm will not be applied to an Initial Alarm and vice versa. The Current Alarm Configuration menus offer the following parameters:

Trigger Enable: Enables/Disables the trigger for this alarm. When Disabled, this alarm will be suppressed. (Default = On.)

Note:

To cancel an alarm without correcting the condition that caused the alarm, simply toggle the Trigger Enable parameter Off and then back On again.

Alarm Set Threshold: The trigger level for this alarm. When current load exceeds the Alarm Set Threshold, the Outlet Managed PDU can send an alarm and/or begin load shedding (if enabled.) Note that the Alarm Set Threshold is entered as a percentage of maximum capacity and is applied to both Over Current Branch Alarm and Over Current Line Alarm (if present.) (Defaults: Initial = 80%; Critical = 90%.)
