CLI command to find the temperature on CSS11503


Appreciate your quick assistance here.

My Customer is working on optimizing the environmental conditions at all his Data Center locations (Currently they are in the range 68F to 74F at their locations and they want to increase the temp to 76F) . So, the customer wants to know the standard low / average / high thresholds of CSS11503 switches that they have in their Data Center locations and the current readings of these switches in their network just to make sure so that they don't raise the temperate in the hot location and end up having platforms shut down because the temperate was raised without confirming the platform and ambient temperature.

After doing some research in CCO, I found this below link which talks about the Ambient Operating temperature.


•Ambient operating temperature is 32° to 104°F (0 to 40°C)

I am trying to find the CLI show command that I can use to get the current readings, but I couldn’t find the show environment temperature command on the customer's production switch.  In my opinion, “show environment temperature” command is kind of a standard command which should be on the switch irrespective of the code that it is running. But for some reason, I couldn’t find it on the production box. Is there any other related CLI show command that gives me this information that I am looking for? I also tried to find the “show diag environment” from the support forum on the production box, but no luck even with this.

Here is the production box,

CLI command to find the temperature on CSS11503

On my SG500-28 I found this command:SG500-28-1#show environment temperature status

but it returns N/A and I don't see a temp on the web gui either but maybe you'll have better luck if this works on your switch.

show system

show system

provides the FAN status and (internal) temperature or our SG500 switches.

this is pretty old request

this is pretty old request already, but... ok.

this command works:

css# llama
css(debug)# show temperature all 

the temperature info is hidden into special debug mode of CSS unit. Command output shows temperature based on slot ("all" for showing all slots). example:

css(debug)# show temperature all
Slot 1 Temperature - 34 degrees C.
Slot 2 is not populated.
Slot 3 is not populated.
Slot 4 Temperature - 32 degrees C.
