All the EX4550 switchmodels, except the EX4550-32F-S switches are shipped with three
fan modules pre-installed in the rear panel of the switches. EX4550-32F-S switches are
not shipped with pre-installed fan modules; you must order them separately.
Two variants of fan modules are available, each with a different airflow
direction—back-to-front airflow, indicated by the label AIR IN (AFI) and front-to-back
airflow, indicated by the label AIR OUT (AFO). See “Cooling System and Airflow in an
EX4550 Switch” on page 35.
CAUTION: Do not mix fan modules with different airflow labels (AIR IN (AFI)
and AIR OUT (AFO)) in the same chassis.
