FAQs

Q: Is this a standalone switch?
A: No. It is a fabric extender (FEX) and must connect to a supported Nexus parent switch.

Q: How many uplinks are available?
A: Six QSFP+ 40G fabric uplinks.

Q: Are optics included?
A: Yes. This bundle includes 4x fabric extender transceivers (FET-10G/FET-40G) or QSFP-40G BiDi as specified at purchase.

Q: Does it support PoE on copper ports?
A: No. The RJ45 ports are non-PoE 100M/1G/10GBASE-T.

Q: What airflow options are available?
A: Port-side intake or port-side exhaust; select at order to match your data center design.

Q: What cabling is recommended for 10GBASE-T?
A: Use Cat6a (or better) for 10G up to 100 meters.

Q: Which QSFP+ optics are supported for uplinks?
A: Common options include QSFP+ SR4/FET-40G (MPO-12) and QSFP-40G BiDi (LC duplex) on MMF.

Q: Are feature licenses required?
A: No local licenses on the FEX; features and policies are controlled by the parent switch.
