The following table describes the labels in this screen.
Table 49 MONITOR > System Information > Hardware Monitor (Stacking Mode)
LABEL DESCRIPTION
This displays the slot ID of the Switch in the stacking system.
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: C (Centigrade) or
F (Fahrenheit) in this field.
Temperature
(C/F)
CPU/MAC, BOARD, and PHY refer to the location of the temperature sensors on the Switch
printed circuit board. The first number represents the slot ID.
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. The first number represents the slot ID.
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. The first number represents the slot ID.
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.
