Dimension ES-3024 Ethernet Switch

	Table 19-4 Hardware Monitor
LABEL	DESCRIPTION
Temperature Unit (C)	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. MAC, CPU and PHY refer to the location of
	the temperature sensors on the switch printed circuit board.
Current	This shows the current temperature in degrees centigrade 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.
Tolerance	A tolerance of plus-minus five percent is the acceptable deviation from the nominal
	voltage.
Status	Normal indicates that the voltage is within an acceptable operating range at this
	point; otherwise Error is displayed.
Poll Interval(s)	The text box displays how often (in seconds) this screen refreshes. You may change
	the refresh interval by typing a new number in the text box and then clicking Set
	Interval.
Stop	Click Stop to halt statistic polling.
