FAQs

Q: What does AFO airflow mean on this switch?
A: AFO indicates air flows from the port side (intake) to the PSU side (exhaust), aligning with cold-aisle at the ports.

Q: Are PoE features available on the 32x100G ports?
A: No. QSFP28 data-center ports do not support PoE.

Q: Does it support EVPN-VXLAN for data center fabrics?
A: Yes, EVPN-VXLAN is supported for modern leaf/spine designs.

Q: Which transceivers are compatible?
A: QSFP28 100G modules (e.g., SR4, LR4, PSM4) and QSFP+ 40G modules are supported when used with appropriate optics/cables.

Q: Is an additional feature license required?
A: Base L2/L3 functionality is available under Junos OS; certain advanced features may require additional entitlement.
