Overtemperature Indications

Overtemperature situations are sensed by the Power Monitor card. There are two overtemperature messages
that occur within the system specified operating temperature range. These messages DO NOT stop the
system or shut off DC power. They are an indication of temperature rise and possible problems. Table 3-10
presents these indications along with the temperature power shutdown message as symptoms with cause and
recommended actions.
