Juniper lists ACX5448-D-FAN-AFI against the ACX5448-D-AC-AFI and ACX5448-D-DC-AFI columns of its Hardware Compatibility Tool. Both columns specify back-to-front cooling. Record the complete installed chassis order before selecting the spare: a matching family name alone does not establish support for a different airflow or chassis variant.
The AC AFI column names JPSU-850W-AC-AFI; the DC AFI column names JPSU-850W-DC-AFI. These are the corresponding power-module references for those two parent configurations, not power supplies included with this fan order. The cooling guide identifies the named D fan as AIR IN with blue markings and requires AIR IN fans and power modules to be paired. Air travels from the rear fan side to the front of the chassis.
The compatibility matrix marks the fan module hot-removable and hot-insertable in both D AFI configurations. That capability does not permit mixing opposite airflow directions or omitting the manufacturer replacement sequence. Confirm the existing module label and revision, prepare the replacement before removal and follow the cooling guide for the permitted replacement interval. A change to the whole airflow pattern requires the complete fan and power-module conversion with the router powered off.
The commercial ordering table identifies ACX5448-D-FAN-AFI as a back-to-front fan tray. Keep the D order code on the enquiry and confirm supplied quantity and revision. A chassis fan count is not the quantity supplied by this listing. This component order does not imply a router, power supplies, software entitlement or an entire fan set. ACX5448-FAN-AFI is a different code; the shared AIR IN description is not evidence of interchangeability.
The original generic ACX5400 fan-module drawing is provided as a Series reference. It is not an exact D-unit photograph and does not verify a blue label on the offered unit. The specifications below describe the fan selection and its parent configuration; router network ports, processor and chassis power consumption are not fan specifications.

ACX5448-FAN-AFO is the Juniper airflow-out fan module for an ACX5448 cooling configuration. Air enters at the front panel and exits through the rear fan modules: ports-to-FRUs, or front-to-back airflow. The exact official table identifies AFO with AIR OUT and orange markings and requires matching AIR OUT power modules. This is a cooling component; a complete router or fan set is not implied. The generic official Series drawing is not a supplied-unit photograph.

ACX5448-FAN-AFI is a Juniper airflow-in fan module for the ACX5448 platform, not a complete router. AFI directs air from the rear fan side toward the front ports. Juniper identifies this order with AIR IN and blue markings; its airflow must match the installed power modules. The official Series fan-module drawing is a reference, not a photograph of the supplied AFI unit.
