FAQs

Q: How do the combo ports work?
A: Each combo consists of one 10G SFP+ and one 10GBase‑T interface sharing the same port logic; only one can be active per combo at a time.

Q: Is a subscription required for features?
A: No. The switch is license‑free.

Q: Can this function as a core for a small network?
A: Yes. With L3 static routing, QoS, and stacking, it suits SMB/core or high‑density access roles.

Q: Does it provide PoE for endpoints?
A: No. This model does not supply PoE power.

Q: What management options are available?
A: Web GUI, CLI (SSH/console), and SNMP are supported.
