About the ACX5448-D-AC-AFO
With 36 SFP+ ports, 2 QSFP28 ports and 2 CFP2 ports, the ACX5448-D-AC-AFO is the optical-leaning member of the ACX5448 family. Throughput is 800 Gbps in a 1U fixed chassis, and the maximum AC draw is 550 W.
Front-to-back airflow means cool air enters at the port side. Software is basic L2 and IGP, so MPLS needs a subscription ordered from Support & Licensing above.

Common questions
AFO or AFI on the D model?
Choose AFO if the port side is your cold aisle. The supplies are JPSU-850W-AC-AFO and air exits at the power-supply side.
How much power should I plan for?
The maximum AC power draw is 550 W, so plan the rack’s power budget around that figure.
Is Juniper Care available for it?
Yes. Care and the software subscription tiers appear in Support & Licensing above.
