On Summit family switches, if a switch runs outside the expected range, the switch logs an error message, generates a trap, and continues running. No components are shutdown. To verify the state of the switch, use either the show switch or show temperature commands. If the temperature exceeds the maximum limit, the show switch output indicates the switch in an OPERATIONAL (Overheat) mode, and the show temperature output indicates an error state due to overheat.
On a SummitStack, use the show temperature command to see the temperature information of all active nodes in the stack.
