• 0201091F: 1V15_SENSE: Voltage sensor, critical event was asserted, reading value %V (Threshold
%V)
Asserted when voltage sensed on 1.15V power rail is higher than high critical threshold.
Severity: Critical
User Action:
1. Reseat SMM module.
2. If 1V15_SENSE error is still asserted, replace SMM module.
• 04010010: FAN_TACH_1A: Fan sensor, warning event was asserted, reading value %RPM
(Threshold %RPM)
Asserted when Fan tach reading is below warning threshold RPM.
Severity: Warning

1. If warning is not de-asserted after several minutes, check all five fans are installed.
2. Reseat fan module a couple of times. If error still persist, replace fan module.
• 04010012: FAN_TACH_2A: Fan sensor, warning event was asserted, reading value %RPM
(Threshold %RPM)
Asserted when Fan tach reading is below warning threshold RPM.
Severity: Warning
User Action:
1. If warning is not de-asserted after several minutes, check all five fans are installed.
2. Reseat fan module a couple of times. If error still persist, replace fan module.
• 04010013: FAN_TACH_2B: Fan sensor, warning event was asserted, reading value %RPM
(Threshold %RPM)
Asserted when Fan tach reading is below warning threshold RPM.
Severity: Warning
User Action:
