CHAPTER 7: Alarm Configuration
109
Note that both the Initial Threshold menus and Critical Threshold menus offer
essentially the same parameters, but the parameters dened for each alarm are
separate and unique. Therefore, parameters dened for the Critical Threshold Alarm
will not be applied to the Initial Threshold Alarm and vice versa. Both the Over
Temperature (Initial Threshold) alarm and the Over Temperature (Critical Threshold)
alarm 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 temperature
exceeds the Alarm Set Threshold, the Outlet Managed PDU can send an
alarm (if enabled) and/or begin Load Shedding (if enabled.) For more
information on Load Shedding for the Over Temperature Alarm, please
refer to Section 7.2.1. (Initial Threshold: Default = 90°F or 32°C, Critical
Threshold: Default = 100°F or 38°C.)
• Alarm Clear Threshold: Determines how low the temperature must drop
in order for the Alarm condition to be cancelled and for Load Shedding (if
enabled) to occur. For more information on Load Shedding for the Over
Temperature Alarm, please refer to Section 7.2.1. (Initial Threshold:
Default = 80°F or 27°C, Critical Threshold: Default = 90°F or 38°C.)
Note:
The System Parameters menu is used to set the temperature format
for the Outlet Managed PDU to either Fahrenheit or Celsius as
described in Section 5.3.
• Resend Delay: Determines how long the Outlet Managed PDU will wait to
resend an email message generated by this alarm, when the initial attempt to
send notication was unsuccessful. (Default = 60 Minutes.)
• Notify Upon Clear: When this item is enabled, the Outlet Managed PDU
will send additional notication when the situation that caused the alarm
has been corrected. For example, when Notify Upon Clear is enabled,
the Outlet Managed PDU will send initial notication when it detects that
the temperature has exceeded the trigger value, and then send a second
notication when it determines that the temperature has fallen below the
trigger value. (Default = On.)
