Airow Through the Chassis
In the PTX10001-36MR cooling system, cool air enters through the vents in the port panel and hot air
exhausts through the FRU panel. This type of airow is known as airow out or port-to-FRU airow.
When the chassis is installed, it must be posioned so that the FRUs are next to the
hot aisle . Figure 11
on page 23 shows the airow through the chassis.
