Recognize an overtemperature condition

An overtemperature 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
