HIL-1601
Message <timestamp>, [HIL-1601], <sequence-number>,, ERROR, <system-name>, Using backup
temperature sensor. Attention needed.
Probable Cause Indicates that temperature readings from the primary sensor are out of range.
Recommended
Action
Run the fanShow command to verify that all fans are operating correctly. Replace any deteriorating
fan field-replaceable units (FRUs).
Run the tempShow command to verify temperature values. If any sensor is too high, monitor the
switch. Try rebooting or power cycling the switch.
Severity ERROR
HIL-1602
Message <timestamp>, [HIL-1602], <sequence-number>, FFDC, CRITICAL, <system-name>,

Probable Cause Indicates that temperature readings from multiple sensors are out of range.
Recommended
Action
Run the fanShow command to verify that all fans are operating correctly. Replace any deteriorating
fan field-replaceable units (FRUs).
Run the tempShow command to verify temperature values. If any sensor is too high, monitor the
switch. Try rebooting or power cycling the switch.
Severity CRITICAL
