The system fan assembly provides cooling air for the internal chassis components. The fan assembly is
a tray of fans that you can insert and remove from the chassis while the system is on line. The
Catalyst 4503 fan assembly has two fans, the Catalyst 4506 fan assembly has four fans, and the
Catalyst 4507R fan assembly has six fans. The fans draw in fresh air from one side and exhaust air on
the other side. Catalyst 4503 airflow is shown in

rebooting the switch in a Catalyst 4506 switch with a Supervisor Engine III or Supervisor Engine IV and
in a Catalyst 4507R switch with Supervisor Engine IV. Starting in December 2002, Cisco added a white
