Environmental Monitoring
The Z9000 components use environmental monitoring hardware to detect transmit power readings,
receive power readings, and temperature updates.
To receive periodic power updates, enable the enable optic-info-update interval command.
The output in the following example displays the environment status of the RPM.

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.
To discover the cause, inspect cards near the one reporting the condition.
• 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 system messages shown in the following example.
