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.

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 flow through the system. Ensure that the air ducts are clean and that all fans are working

correctly.
