PROTECTIVE SHUTDOWN - CHECK AIRFLOW THEN CYCLE POWER

• The airflow for C3850-48XS switches will depend on the power supply and fans installed. Ensure that the power supplies are inserted correctly to match the corresponding fans. Power supplies with blue handles correspond to fans with blue handles, and power supplies with red handles correspond to fans with red handles.

  • For power supplies and fans with red handles, airflow is from the front panel to the rear panel (warm air is ‘pulled out of’ the switch.)

  • For power supplies and fans with blue handles, airflow is from the rear panel to the front panel (cool air is ‘pushed into’ the switch.)
