9200cx switch maximum temperature

[stephen.neal]

We have noticed somewhat of a discrepancy between the datasheet maximum temperature values for the 9200cx switches and what shows up in the CLI.  So, we are trying to find something more definitive on the maximum temperature and at what temperature the switch will shutoff to protect itself(as stated in the 9200cx white paper).

The 9200 datasheet basically lists all maximum temps as:

Normal operating temperature* and altitudes:

●  -5°C to +45°C, up to 5000 feet (1500m)

(-5°C to +40°C for C9200CX-8UXG-2X and C9200CX-8UXG-2XH)

But on the cli for a C9200CX-8P-2X2G we have out in the field it says:

gtb-lot86-9200cx-1#show environment temperature
Switch 1: SYSTEM TEMPERATURE is OK
Inlet Temperature Value: 49 Degree Celsius
Temperature State: GREEN
Yellow Threshold : 74 Degree Celsius
Red Threshold    : 81 Degree Celsius

Hotspot Temperature Value: 57 Degree Celsius
Temperature State: GREEN
Yellow Threshold : 105 Degree Celsius
Red Threshold    : 125 Degree Celsius

Would really like to get a better understanding of the real specifications for this switch.

    - The datasheet should probably be considered authoritative ; the problem being that the CLI 'comes from the OS' and
       may not always make sufficient differences between models ,

Hello @stephen.neal ,

the show environment temperature output provides you the reading of the thermal sensors inside the switch.

49 Celsius degrees measured in the inlet ,

And another reading for the hotspot.

The datasheet provides you info about the temperature range of the room where you place the switch.

-5 to 40 degrees celsius is the external temperature in the room.

The switch inside is more hot then the external environment.

Hope to help
