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.

Recognize an Over-Temperature 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.
NOTE:
When the ingress air temperature exceeds 61°C, the Status LED turns Amber and a major
alarm is triggered.

Troubleshoot an Over-Temperature Condition
To troubleshoot an over-temperature condition, use the following information.
1.
Use the
show environment
commands to monitor the temperature levels.
2.
Check air flow through the system. Ensure that the air ducts are clean and that all fans are working
correctly.
