Environmental monitoring

The S4810 components use environmental monitoring hardware to detect transmit power readings, receive
power readings, and temperature updates. To receive periodic power updates, the
command must be enabled. The output in

Recognize an over-temperature condition

An over-temperature condition occurs, for one of two reasons:
• The card genuinely is too hot.
• 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 system messages in
Message 3 Over Temperature Condition 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
