High Temperature Alarm Threshold: 80C (176F)
Low Temperature Alarm Threshold: 0C (32F)
(Hysteresis value: +/- 5C)

Hysteresis

is the amount the temperature must change past the set alert threshold
before the alert condition is cleared. For a device with two service ports, hysteresis
value is fixed at ± 5 degrees. For example, if you specify a high-temp-threshold of
75°C, you will get ELS messages from 75 degrees and above. The temperature
must go below 70 degrees before the condition is cleared (75-5=70). If you
specify a low-temp-threshold of -10°C, you will get ELS messages from -10 degrees
and below. The temperature must move above -5 degrees before you no longer get
ELS messages (-10 +5 = -5).

Set:

Use the set command to set the high and low temperatures at which the
system raises an alarm condition.
Note: The reset temperature level is factory set. Youcannot modify it.
Syntax:
set high-temp-threshold
low-temp-threshold
recalc-temp-interval
high-temp-threshold

degrees_celcius

Sets the high temperature at which you will receive ELS messages before
the router resets. The value should be about 10°C less than the maximum
(85°C) so that you get some ELS messages before the router resets itself.
low-temp-threshold

degrees_celcius

Sets the low temperature at which you will receive ELS messages. The
value should be about 10°C more than the minimum (−55°C) so that you
get some ELS messages. The router does not reset itself on cold
temperatures.
Note: Temperatureranges vary depending on the environment in which you place
the router. Use the environment command described on page 66to
determine your router’s natural operating range over time.
recalc-temp-interval
seconds
Sets the amount of time between successive temperature readings.
Valid values: 10 to 86400 seconds
Default value: 60
Event
Use the event command to enter the Event Logging System (ELS) environment so
that you can define the messages that will appear on the console. Refer to
“Chapter 12. Using the Event Logging System (ELS)”on page 147 for information
about ELS.
