It suits top-of-rack and aggregation roles in data center and campus networks. This unit is the back-to-front (port-side exhaust) airflow version: cooling air enters at the fan and power supply side and leaves at the port side.

Fan choices are the N9K-C9300-FAN3-B (port-side exhaust) or N9K-C9300-FAN3 (port-side intake) - note the N9K suffix logic is reversed on this model. Power supply choices are the N9K-PAC-650W-B AC (port-side exhaust) or N9K-PAC-650W AC (port-side intake). The N9K-C9300-ACK rack kit fits this chassis.
