FAQs

Q: Does this switch require a recurring license or subscription?
A: No. It is license-free; all features are available out of the box.

Q: What optics and cables can I use on the SFP+ uplinks?
A: Standard 10GbE SFP+ optical modules and DAC cables are supported. Use compatible SFP+ modules and check device release notes for specific part compatibility.

Q: Can I use both copper and SFP+ on the combo ports at the same time?
A: No. Each combo port pair shares one interface; only one medium (10GBase-T or SFP+) can be active per combo port.

Q: What is the maximum PoE per port?
A: Up to 30W per port under 802.3at (PoE+), subject to the total 740W power budget.

Q: Can it be stacked with other 550X series models?
A: Yes. Stacking is supported within the 550X series for unified management. Refer to software release notes for any model or version requirements.
