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.
