Recognize an Overtemperature Condition
An overtemperature condition occurs, for one of two reasons: the card genuinely is too hot or a sensor has malfunctioned.
Inspect cards adjacent to the one reporting the condition to discover the cause.
● If directly adjacent cards are not normal temperature, suspect a genuine overheating condition.
● If directly adjacent cards are normal temperature, suspect a faulty sensor.
When the system detects a genuine over-temperature condition, it powers off the card. To recognize this condition, look for the
following system messages:
CHMGR-2-MAJOR_TEMP: Major alarm: chassis temperature high (temperature reaches or
exceeds threshold of
[value]C)
CHMGR-2-TEMP_SHUTDOWN_WARN: WARNING! temperature is [value]C; approaching shutdown
threshold of [value]C
To view the programmed alarm thresholds levels, including the shutdown value, use the show alarms threshold command.
Example of the show alarms threshold Command
