About the ACX5448-A-AC-AFO
ACX5448-A-AC-AFO is the bundle version of the ACX5448: a 1U fixed router with 48 SFP+ ports, 4 QSFP28 ports and 800 Gbps of throughput, on AC power with front-to-back airflow. Most ACX5448 SKUs are sold without feature rights; this one comes with its rights, so it can be put to work on L2 and IGP as soon as it is racked.
The bundle includes L2 features, IGP, all 48 10GbE ports, all 4 100GbE ports, all 1GE, 25GbE and 40GE ports, and a FIB up to 256K. It has no right to use MPLS, VRF or BGP, so a design that needs them should check the license tiers in Support & Licensing above.

Common questions
Does this one need a feature license to carry traffic?
Not for L2 and IGP. The bundle already covers L2 features, IGP and every port. It does not include rights for MPLS, VRF or BGP.
What do I give up compared with the R bundle?
This A bundle stops at L2 and IGP with a 256K FIB. The ACX5448-R-DC-AFI is the version listed with MPLS and BGP rights, but it is a DC unit with back-to-front airflow.
AFO means which direction for my rack?
AFO here is front-to-back: air enters at the port side and leaves at the power-supply side. Its two JPSU-650W-AC-AO supplies run 1+1 and are hot-swappable.
