If the amber fault LED is lit, remove power from the power supply, and replace the
power supply (see"Removing a Power Supply from an EX4600 Switch" on page 169
). Do not remove the power supply until you have a replacement power supply ready:
the power supplies or a blank cover panel must be installed in the switch to ensure
proper airflow.
CAUTION: Replace a failed power supply with a blank panel or new power
supply within 1 minute of removal to prevent chassis overheating.
