Common questions
Is this front-to-back or back-to-front?
It is back-to-front, so air enters at the power-supply side and leaves at the port side. Listed power: 2x JPSU-650W-DC-AFI.
Does it work out of the box without a license?
Yes. The standard software provides many features without a tier license on the 48x SFP+, 4x QSFP28 ports; Advanced 1, Advanced 2 and Cloud-based threat feeds are add-ons, listed in Support & Licensing above. Juniper Care is offered too.
Did the hardware change with the AFI2 and AFO2 part numbers?
Same hardware.. Juniper’s AFI2 and AFO2 part numbers cover the same hardware as the earlier AFI and AFO versions. It has 48x SFP+, 4x QSFP28 and 2x JPSU-650W-DC-AFI.
