Configuring Fan Unit Assertion Levels
The fan unit, by default, sends an active-low signal to TAC to report fan
temperature and rotation faults. You configure the fan unit to send an
active-high signal if so specified by the fan unit vendor.
To configure the fan unit assertion level, perform the following tasks:
To display the fan unit assertion levels currently configured for both fan
temperature and rotation fault indications, perform the following tasks:
Example
The following example displays the assertion level currently configured for
the fan temperature:
cli:192.168.208.3:root# show aux-device fan-temp
Assert Fan Temp Fault active-high
Task Command
1. Enter configuration mode. root
2. Set the assertion level of the
signal used to report fan
temperature faults to the
management module.
aux-device fan-temp fault-level
{active-high | active-low}
3. Set the assertion level of the
signal used to report fan
rotation faults to the
management module.
aux-device fan-rotation fault-level
{active-high | active-low}
Task Command
1. Enter configuration mode. root
2. Display the assertion level
currently configured for the
reporting of fan temperature
faults.
show aux-device fan-temp
3. Display the assertion level
currently configured for the
reporting of fan rotation
faults.
show aux-device fan-rotation
