Appendix B: Thermal Threshold Definitions
There are three thermal threshold definitions for the SwitchIB® switch device which impact the
overall switch system operation state: Warning, Critical and Emergency.
1.Warning – 105°C
On managed systems only: When the device crosses the 100°C threshold, a Warning
Threshold message will be issued by the MLNX-OS management SW, indicating 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).
2.Critical – 120°C
When the SwitchIB® device crosses this temperature, the firmware will automatically shut down
the device.
3.Emergency – 130°C
In case the firmware fails to shut down the SwitchIB® device upon crossing the Critical thresh-
old, the device will auto-shutdown upon crossing the Emergency (130°C) threshold.
