Common questions
Which direction does air travel through the chassis?
Air enters at the port side and leaves at the power-supply side, which is front-to-back cooling. A fully loaded unit draws up to 312 W on AC.
Is a tier license required for basic use?
No. You can run the standard software without one on the 32x QSFP28 ports, and add Advanced 1, Advanced 2 and Premium 1 later from Support & Licensing above. Juniper Care is offered too.
Do the AFI2 and AFO2 versions differ from the older AFI and AFO SKUs?
Same hardware.. Juniper’s AFI2 and AFO2 part numbers cover the same hardware as the earlier AFI and AFO versions. It has 32x QSFP28 and 2x JPSU-850W-AC-AFO.
