Common questions

Is this front-to-back or back-to-front?

It is front-to-back, so air enters at the port side and leaves at the power-supply side. Listed power: 2x QFX520048Y-APSU-AO.

Does the AFO configuration support a switch pair?

Yes. Virtual Chassis supports two members operating together under shared management.

Does it work out of the box without a license?

Yes. The standard software provides many features without a tier license on the 2x SFP+, 32x QSFP28 ports; Advanced 1, Advanced 2 and Premium 1 are add-ons, listed in Support & Licensing above. Juniper Care is offered too.
