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 o 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

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 ow through the system. Ensure that the air ducts are clean and that all fans are working correctly.
3. After the software has determined that the temperature levels are within normal limits, you can re-power the card safely. To
bring back the line card online, use the power-on command in EXEC mode.
