7-7 Alarm Configuration 7.2. The Over T emperature Alarms The Over T emperature Alarms are designed to inform you when the temperature level inside your equipment rack reaches or exceeds certain user -defined levels. There are two separate Over T emperature Alarms; the Initial Threshold alarm and the Critical Threshold Alarm.
7-8 Alarm Configuration Both the Over T emperature (Initial Threshold) alarm and the Over T emperature (Critical Threshold) alarm offer the following parameters: • T rigger Enable: Enables/Disables the trigger for this alarm. When Disabled, this alarm will be suppressed.
