Enabling Environmental Monitoring
The S5000 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.
