Which QFX5120 do I need?
Choose by server connection: 25 GbE SFP28 on the 48Y, 10GBASE-T copper on the 48T, or 100 GbE on the 32C. Power supply part numbers differ by model and airflow, so match the supply to your exact switch. Check the airflow stated in the listing; AFO is front-to-back and AFI is back-to-front, and the switch, fans and power supplies should all match. Some part numbers carry a hardware revision suffix, such as AFO2, so match it if you are replacing a unit in an existing fabric. Check whether the switch is AC or DC powered. Give us your part numbers and Junos release and we will confirm the match.
Frequently asked questions
Can the 25 GbE ports run at 10 GbE?
Generally yes. The SFP28 ports on the 48Y can run 10 GbE with SFP+ optics or cables, depending on the port configuration and Junos release.
