FAQs

Q: Does this switch provide PoE?
A: No. The -T model is non-PoE.

Q: Are the SFP+ ports shared with copper ports?

Q: Do I need licenses or subscriptions to enable features?
A: No license tier is required; features are included.

Q: Which optical modules are supported on the SFP+ uplinks?
A: Standards-compliant 10G SFP+ optics (e.g., SR/LR) and 10G SFP+ DAC/AOC cables are supported; check compatibility before purchase.

Q: Can I run 10GBase-T over existing cabling?
A: 10GBase-T is specified for Cat6a up to 100 m; shorter runs may work on Cat6, but Cat6a is recommended.
