User Action:
1. Reseat SMM module.
2. If 12V_SENSE error is still asserted, replace SMM module.
• 0201021B: 3V3_SENSE: Voltage sensor, critical event was asserted, reading value %V (Threshold
%V)
Asserted when voltage sensed on 3.3V power rail is lower than lower critical threshold or higher than
upper critical threshold
Severity: Critical
User Action:
1. Reseat SMM module.
2. If 3V3_SENSE error is still asserted, replace SMM module.
• 0201021C: 5V_SENSE: Voltage sensor, critical event was asserted, reading value %V (Threshold %
V)
Asserted when voltage sensed on 5V power rail is lower than lower critical threshold or higher than upper
critical threshold
Severity: Critical
User Action:
1. Reseat SMM module.
2. If 5V_SENSE error is still asserted, replace SMM module.
• 0201021D: 2V5_SENSE: Voltage sensor, critical event was asserted, reading value %V (Threshold
