Status Potential Cause Possible Resolution
Off Normal condition N/A
Steady Red
SM internal temperature
exceeds operating
temperature specification
Shunt module fan failed Replace shunt module.
Shunt module temperature exceeds rating
• Allow shunt module to cool.
• Reset faults.
• Verify IAM bus regulator configuration.
External over temperature
condition
External temperature switch is open
• Allow shunt module to cool.
• Reset faults.
• Verify IAM bus regulator configuration.
TS jumper is not present Install jumper.
