General Setup in the navigation panel to display the screen as shown.
Hardware Monitor (The following hardware monitoring information is only available on the PWR
model.)
Temperature
Unit The Switch has temperature sensors that are capable of detecting and reporting if the
temperature rises above the threshold. You may choose the temperature unit
(Centigrade or Fahrenheit) in this field.
Temperature CPU , MAC and LOCAL refer to the location of the temperature sensors on the
Switch printed circuit board.
Current This field displays the current temperature measured 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.
Status This field displays Normal for temperatures below the threshold and Error for those
above.
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.
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.
Status Normal indicates that this fan is functioning above the minimum speed. Error
indicates that this fan is functioning below the minimum speed.
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.
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 minimum voltage at which the Switch should work.
Status Normal indicates that the voltage is within an acceptable operating range at this
point; otherwise Error is displayed.
