Technical Specifications

FAQs

Q: Can this unit operate as a standalone switch?
A: No. It is a Fabric Extender (FEX) and requires a compatible parent Nexus switch; all control and forwarding are handled by the parent.

Q: Which parent switches are supported?
A: Supported Cisco Nexus platforms with FEX support (e.g., select Nexus 5K/6K/7K/9K) running a compatible NX-OS release.

Q: Are power supplies and fans included?
A: No. This spare chassis SKU ships without PSUs or fan modules.

Q: Does it support 10G operation on QSFP+ uplinks?
A: Yes, with QSFP-to-SFP+ QSA adapters you can present a single 10G SFP+ per QSFP+ cage.

Q: Is PoE supported on the host ports?
A: No. Host ports are data-only SFP/SFP+.

Q: What optics are supported on host ports?
A: Standard 1G SFP and 10G SFP+ modules, including short- and long-reach options, subject to parent switch compatibility.

Q: Is any software license required on the FEX?
A: No license is required on the FEX; features and licensing are applied on the parent switch.
