Emergency Actions
Catalyst 4500 chassis can power down a single card, providing a detailed response to over-temperature
conditions on line cards. However, the Catalyst 4500 chassis cannot safely operate when the temperature
of the supervisor itself exceeds the critical threshold. The supervisor engine turns off the chassis’ power
