For ACX5448-FAN-AFO, Juniper lists AIR OUT and orange identification in the fan-module table. The front panel is the intake side; air leaves the chassis through the fan modules at the rear. This ports-to-FRUs orientation matters when choosing a spare for a rack with a fixed cooling direction. Check the installed router product number, existing labels and required revision before requesting availability.
An AFO fan choice must match the power modules: Juniper requires AIR OUT power supplies with AIR OUT fan modules. Its chassis guidance places AIR OUT components toward the hot aisle and AIR IN components toward the cold aisle. A single airflow-in replacement is not an equivalent cooling choice. If the deployment needs a different airflow pattern, the manufacturer requires a complete fan and power-module conversion with the device powered off.
The datasheet names ACX5448-FAN-AFO as a fan order, and its legacy Left description does not establish a left-hand mounting slot. ACX5448-D-FAN-AFO is a separate code in the airflow table; sharing an AIR OUT designation is not proof of cross-model interchangeability. State the exact installed product and component code, and confirm the quoted quantity rather than assuming that a fan listing supplies all chassis fans, power modules or a complete router.
Juniper describes these fan modules as field-replaceable and limits the time allowed for a replacement. Plan the procedure from the hardware guide and confirm the delivered label before installation. The original generic ACX5400 fan-module drawing is a Series reference; it does not show an offered AFO unit or verify an orange handle on the supplied part.
