Enabling Environmental Monitoring

The device components use environmental monitoring hardware to detect transmit power readings, receive power readings, and
temperature updates.
To receive periodic power updates, you must enable the following command.
• Enable environmental monitoring.
enable optic-info-update interval

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
Voltage
ok
