Troubleshooting

Fan Alarm LED is ON

PROBLEM: One of the chassis in the stack is reporting a fan failure (i.e., the FAN ALM LED of that chassis is on).

A built-in feature shuts off power to the circuit cards if a chassis overheats because of fan failure. If the temperature in the chassis reaches 70°C, power to the cards in the chassis is turned off automatically. Power is turned on when the temperature drops below 60°C.

ACTION: Go to the stack to see which chassis is reporting the fan alarm. To clear the fan alarm, contact your service technician to replace the HotWire 8600 chassis.
