About the ACX5448-AC-AFO
The ACX5448-AC-AFO has 48 SFP+ ports and 4 QSFP28 ports in a 1U fixed chassis, with 800 Gbps of throughput. It uses front-to-back airflow: cool air enters at the port side and leaves at the power-supply side.
Two AC supplies (JPSU-650W-AC-AO, 1+1) and six fans (ACX5448-FAN-AFO) are hot-swappable. The SKU has no feature rights built in, so add the L2, IGP or MPLS rights you need from Support & Licensing above.

Common questions
Is this the AFO or the AFI airflow?
AFO. Cool air comes in at the port side and warm air leaves at the power-supply side. The AFI model reverses that.
Does the 450 W figure mean I need big circuits?
450 W is the maximum AC draw listed for this chassis, so a standard AC feed is enough for planning.
Are the feature rights part of the price?
No. Feature rights to use must be ordered separately.
