Identifying the airflow direction

Caution
If you do not install a module or a power supply in a slot, you must keep the slot filler panel in
place. If you run the chassis with an uncovered slot, the system will overheat.
Identifying the airflow direction
The power supply and fan assemblies are identified by the following airflow directions:
•
Intake power supply and fan assembly with an orange "I" label or without any label: Pulls air from the
nonport-side of the switch and exhausts it out the port side.
•
Exhaust power supply and fan assembly with a green "E" label: Pulls air from the port side of the
switch and exhausts it out the nonport-side.

Times and items required

Installing or removing and replacing a fan assembly should require less than five minutes to complete.
The following items are required to replace a fan assembly:
•
New fan assembly (must have the same airflow direction as the fan assembly being replaced)
•
#1 Phillips screwdriver
