Temperature Log
This subsection provides user and system temperature logs. There are summary statistics and distribution of
temperature information for each log. The highest temperature, the lowest temperature and the average
temperature are reported in degree Celsius. Additionally, there is a recorded time which shows the time since the
temperature log were recorded. Under the summary statistics, there is a table showing the ranges of temperature,
percentages of time in each range, and amount of time in each range. The user can reset the user statistics by
clicking on the
Reset
button at the bottom of User Temperature Log. However, the system temperature log cannot
be reset by the users. Note that the information is not automatically update. Information provided in this webpage
will help the users to monitor the status of the industrial managed switch in harsh environment. The users have to
click reload on the web browser to update for the latest statistics. Figure 2.15 shows the
User Temperature Log
box and Figure 2.16 shows the
System Temperature Log
box
.
Note that there is a sensor component in the industrial managed switch which can detect the inside temperature.
The software inside the switch can read the sensor
’s data and transform it into temperature in a unit of degree
Celsius. Because the device is airtight, the inside temperature will be higher than the outside temperature around
20 degrees. For the industry level switches, the lowest operating temperature (outside) will be around
-20 to -40
degrees Celsius and the highest operating temperature (outside) will be around 70 to 85 degrees Celsius
