About Environmental Monitoring
If a 9000W power supply is installed in the left bay, the show logging onboard subslot 0 detail
command displays logging information for that power supply.
If a 9000W power supply is installed in the right bay, enter the show logging onboard subslot 1 detail
command, as follows:
Switch# show logging onboard subslot 0 detail

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
supplies to protect itself from overheating. When this happens, you can recover the switch only by
cycling the power on and off switches on the power supplies or by cycling the AC or DC inputs to the
power supplies.
Critical and shutdown temperature emergencies trigger the same action. Table 14-2 lists temperature
emergencies but does not distinguish between critical and shutdown emergencies.
Table 14-2 Emergency and Action
Case 1. Complete fan failure emergency. Power down the chassis.
Case 2. Temperature emergency on a line
card.
Power down the line card.
Case 3. Temperature emergency on the
standby supervisor engine.
Power down the standby supervisor engine.
