Remaining
Power (W)
This field displays the amount of power the switch can still provide for PoE.
Note: The switch must have at least 16W of remaining power in order
to supply power to a PoE device; even if the PoE device
requested for a lower power supply than 16W.
Hardware Monitor
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 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.
If Error displays, check that the fans are working and make sure that you do not block
ventilation holes on the switch.
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).
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.
If Error displays, it is recommended that the fan(s) on the switch be replaced by a
qualified technician.
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 percentage tolerance of the voltage with which the switch still
works.
Status Normal indicates that the voltage is within an acceptable operating range at this
point; otherwise Error is displayed.
If Error displays, an electronic component might be defective. Have the switch
serviced by a qualified technician.
