Comware

I just received my 1920-8G non poe switch with the latest firmware 5.20.99 Release 1108 running normally. However I noticed that the temperature monitor in the Summary-->System information page is constantly 0 celcius degree. I looked into the manual of this switch located at

and to my surprise on page 20 it has a screenshot of the system information page showing exactly the same I saw: 0 degree temperature.

So I wonder does that mean I received a faulty unit or that feature has not been implemented yet, or perhaps 1920 does not have a built-in temperature sensor at all? Thanks!

My 1920-24g also shows 0 degrees.
I also tried to find temperature using snmp walk, but wasn't successful.

Maybe temperature reading is only supported on POE devices, with their bigger power supplies

Strangely enough, in this youtube video the speaker has a 24G-POE model of 1920 and he seems to have 0 temperature issue as well...
