The switch contains fan units consisting of individual fans. The switch's cooling subsystem enables querying for specific temperatures and thresholds for the overall chassis, fan units, and individual fans.
Use this task to display information about the system-level health of cooling and airflow for the switch.
For example, to see the ambient temperature of the overall switch, type:
-> show -d properties /SYS/MB/T_AMB
/SYS/MB/T_AMB
Properties:
type = Temperature
ipmi_name = MB/T_AMB
class = Threshold Sensor
value = 33.000 degree C
upper_nonrecov_threshold = N/A
upper_critical_threshold = 43.000 degree C
upper_noncritical_threshold = 38.000 degree C
lower_noncritical_threshold = 8.000 degree C
lower_critical_threshold = 3.000 degree C
lower_nonrecov_threshold = N/A
alarm_status = cleared
All three entities, the chassis, HCA, and IB switch chip, show the same type of information.
