Status This field displays Normal for temperatures below the threshold and Error for those above.
Current This shows the current temperature at this sensor.
MAX This field displays the maximum temperature measured at this sensor.
MIN This field displays the minimum temperature measured at this sensor.
Threshold This field displays the upper temperature limit at this sensor.
Fan Speed
(RPM) A properly functioning fan is an essential component (along with a sufficiently ventilated, cool
operating environment) in order for the device to stay within the temperature threshold. Each
fan has a sensor that is capable of detecting and reporting if the fan speed falls below the
threshold shown.
Status Normal indicates that this fan is functioning above the minimum speed. Error indicates that this
fan is functioning below the minimum speed.
Current This field displays this fan's current speed in Revolutions Per Minute (RPM).
MAX This field displays this fan's maximum speed measured in Revolutions Per Minute (RPM).
MIN This field displays this fan's minimum speed measured in Revolutions Per Minute (RPM). "<41" is
displayed for speeds too small to measure (under 2000 RPM).
Threshold This field displays the minimum speed at which a normal fan should work.
Voltage(V) The power supply for each voltage has a sensor that is capable of detecting and reporting if the
voltage falls out of the tolerance range.
Status Normal indicates that the voltage is within an acceptable operating range at this point;
otherwise Error is displayed.
Current This is the current voltage reading.
MAX This field displays the maximum voltage measured at this point.
MIN This field displays the minimum voltage measured at this point.
Threshold This field displays the percentage tolerance of the voltage with which the Switch still works.
Power Source This field lists the power supply modules installed in the Switch. PSU_1 is PWR1 , and PSU_2 is PWR2 .
Status Active indicates the Switch is currently operating from the power source to which the power
module is connected.
Standby indicates the power module is connected to a power source but the Switch is NOT
operating from it.
N/A is displayed when the power module is not connected to a power source and there is no
available power.
Hardware Monitor (Stacking Mode)
Slot This number identifies the Switch in the stack. Click the number to see more detailed information
on the Switch.
Name This is the system name of the Switch in the stack.
Voltage This shows if the power supply voltage sensor is within normal tolerance range.
Temperature This shows if the temperature sensors on the Switch printed circuit board are within normal
tolerance range.
Fan This shows if the fan sensors are within normal tolerance range.
Power Supply This shows if the Switch is properly operating from the connected power source.
