Recommended
Action
For the SilkWorm 3900 replace the fan FRU.
For the SilkWorm 3016, 3250 and 3850, the entire switch must be replaced, because these switches do
not have FRUs.
Severity ERROR
HIL-1206
Message
Probable
Cause
Indicates that the specified fan speed (in RPM) has fallen below the minimum threshold. This problem
can quickly cause the switch to overheat. This message is specific to nonbladed switches and is not
applicable to the SilkWorm 12000, 24000, or 48000.
Recommended
Action
For the SilkWorm 4100, 4900 and 7500 replace the fan FRU.
Severity ERROR
HIL-1207
Message
Probable
Cause
Indicates that the fan is faulty.
Recommended
Action
Use the tempShow command to verify that the switch temperatures are within operational range. Refer
to the hardware reference manual for the temperature range of your switch.
Make sure that the area is well ventilated and that the room temperature is within operational range of
your switch. Refer to the hardware reference manual for your switch for the operational temperature
range.
Use the fanShow command to monitor the status of the fan generating this error.
If the fan continues to generate this message, replace the switch because the fan is not field-replaceable.
