Alarm Configuration
7.5. The Lost Voltage (Line In) Alarm
The Lost Voltage (Line In) Alarm is intended to provide notification when one of the
power input lines connected to the MPC unit, is lost or disconnected. When one of the
power supplies is lost, the MPC can provide notification via Email, Syslog Message or
SNMP Trap.
Notes:
• The Lost Voltage (Line In) alarm will provide notification when one of the
available power supplies is lost or disconnected. This alarm will not function
if all input power to the MPC unit is lost. To provide notification when all input
power is lost and restored, please use the Power Cycle Alarm as described
in Section 7.8.
• In order for the MPC to provide alarm notification via Email, communication
parameters must first be defined as described in Section 5.9.11.
• In order for the MPC 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 MPC 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 Lost Voltage (Line In) Alarm, access the MPC command mode using a
password that permits Administrator Level commands, and then proceed as follows:
• Text Interface: Type /AC and then press [Enter] to display the Alarm Configuration
Menu. From the Alarm Configuration Menu, type 7 and press [Enter] to access the
configuration menu for the Lost Voltage (Line In) Alarm.
• Web Browser Interface: Click the "Alarm Configuration" link, located on the
left hand side of the screen to display the Alarm Configuration Menu. From the
Alarm Configuration Menu, click on the "Lost Voltage (Line In)" link to access the
configuration menu.
The Lost Voltage Alarm Configuration menu offers 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.
• Resend Delay: Determines how long the MPC will wait to resend an email
message generated by this alarm, when the initial attempt to send the notification
was unsuccessful. (Default = 60 Minutes.)
• Notify Upon Clear: When this item is enabled, the MPC will send additional
notification when the situation that caused the alarm has been corrected. For
example, when Notify Upon Clear is enabled, the MPC will send initial notification
when it detects that one of it's power supplies has been lost or disconnected, and
then send a second notification when it determines that power has been restored.
(Default = On.)
