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.
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.
