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 QFX520048Y-DPSU-AI.
Does DC input change the 32C member limit?
This model supports up to two members managed together as a Virtual Chassis.
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.
