MONITOR
The following sections introduce the MONITOR screens.
What You Can Do
Use the System Information screen to check the firmware version number and monitor the Switch temperature.
System Information
Use this screen to view general system information. You can check the firmware version number and monitor the Switch temperature.

System Information
System Name
This field displays the descriptive name of the Switch for identification purposes.
Product Model
This field displays the product model of the Switch. Use this information when searching for firmware upgrade or looking for other support information in the website.
ZyNOS F/W Version
This field displays the version number of the Switch 's current firmware including the creation date.
Ethernet Address
This field refers to the Ethernet MAC (Media Access Control) address of the Switch.
CPU Utilization Current (%)
CPU utilization quantifies how busy the system is. Current (%) displays the current percentage of CPU utilization.
Memory Utilization
Memory utilization shows how much DRAM memory is available and in use. It also displays the current percentage of memory utilization.
Name
This field displays the name of memory pool.
Total (byte)
This field displays the total number of bytes in this memory pool.
Used (byte)
This field displays the number of bytes being used in this memory pool.
Utilization (%)
This field displays the percentage (%) of memory being used in this memory pool.
Hardware Monitor
Temperature (C/F)
BOARD/MAC/PHY (POWER – for GS2220-10HP only) refers to the location of the temperature sensor on the Switch printed circuit board.
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.
