In an open EIA rack, using the following items:
– The rack-mount kit shipped with the device
– The EIA Shelf Bracket Kit (an optional kit, purchased separately)
In a perforated or solid-walled EIA cabinet, using one of the following:
The rack-mount kit shipped with the device
–

Position the chassis so that its air intake side (front side for front-to-back airflow or back side for
back-to-front airflow) is in a cold aisle. Otherwise, an overtemperature condition can occur and the
system can shut down.
Avoid having the air intake where other systems exhaust air.
Due to the shallow depth of the Cisco Nexus 2000 Series FEX, it is also possible for air to recirculate
across the top and bottom of the chassis in a partially populated rack.
Make sure that the fan tray and power supply modules all use the same direction of airflow. All of
the modules should have no black stripe (front-to-back airflow) or all of the modules should have a
black stripe (back-to-front airflow).
Maintain ambient airflow throughout the data center to ensure normal operation.
