FAQs

Q: Does this model provide Power over Ethernet (PoE)?
A: No. The 48x RJ-45 ports are 10GBASE-T data ports without PoE.

Q: What is the airflow direction for AFI?
A: AFI draws cool air from the PSU side and exhausts warm air at the port side (front-to-back).

Q: Are transceivers and DACs included?
A: No. Optics and cables are sold separately.

Q: Can the QSFP28 100G uplinks be broken out?
A: Yes, they support breakout to 4x25G with appropriate breakout cables or transceivers.

Q: What license tier is required for EVPN-VXLAN?
A: The platform supports L3 and EVPN-VXLAN under the standard license; some advanced features may require additional licensing based on software entitlement.

Q: Is the copper port speed fixed at 10G?
A: Ports typically support 1G/10G; check release notes for any intermediate NBASE-T rates.
