CHAPTER 7: Alarm Configuration
103
The Load Shedding feature can be congured 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 congured 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 congure the Over Current Alarms, access the Outlet Managed PDU command
mode using a password that permits Administrator Level commands, and then use
the Alarm Conguration menu to select the desired alarm feature.
Note that the conguration menus for both Over Current Alarms offer essentially
the same set of parameters, but the parameters dened for each alarm are separate.
Therefore, parameters dened for a Critical Alarm will not be applied to an Initial
Alarm and vice versa. The Current Alarm Conguration 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%.)
