The Over Temperature Alarms
The Over Temperature 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 Temperature Alarms; the Initial Threshold alarm and the
Critical Threshold Alarm.
Typically, the Initial Threshold alarm is used to notify you when the temperature
within your equipment rack reaches a point where you might want to investigate
it, whereas the Critical Threshold alarm is used to notify you when the temperature
approaches a level that may harm equipment or inhibit performance. The trigger for
the Initial Threshold alarm is generally set lower than the Critical Threshold alarm.
If the user-defined trigger levels for temperature are exceeded, the Outlet Managed
PDU can automatically shut off power to non-essential devices ("Load Shedding")
in order to reduce the amount of temperature that is being generated within the rack.
In addition, the Load Shedding feature can also be used to switch On additional
components, such as fans or cooling systems in order to dissipate the excess heat.
After Load Shedding has taken place, the Load Shedding Recovery feature can
be used to return plugs to their previous state after the temperature drops to an
acceptable level.
