Appendix B: Thermal Threshold Definitions
There are three thermal threshold definitions for the switch device which impact the overall
switch system operation state:
• Warning – 105°C: On managed systems only: When the device crosses the 100°C
threshold, a Warning Threshold message will be issued by the management SW, indicat-
ing to system administration that the switch has crossed the Warning threshold. Note
that this temperature threshold does not require nor lead to any action by hardware
(such as switch shutdown).
• Critical – 120°C: When the device crosses this temperature, the firmware will automati-
cally shut down the device.
• Emergency – 130°C: In case the firmware fails to shut down the device upon crossing
the Critical threshold, the device will auto-shutdown upon crossing the Emergency
(130°C) threshold.
