and the power supply panels, circulates through the chassis and the power supplies, and exhausts
at the network port side, as shown in

.
•
When LSWM1FANSCB fan trays are used, cool air flows in through the air vents in the network
port-side panel and the power supply panels, circulates through the chassis and the power supplies,
and exhausts through the air vents in the fan tray panels, as shown in
