Cisco Nexus Switches - Refurbished, Used, New
Cisco Nexus switches are Cisco's data center switches, used to connect servers, storage and the network core, from 1 GbE server ports to 400 GbE spine switches. The Nexus 3000 through 9000 switches run NX-OS, and many Nexus 9000 models can instead run in Cisco ACI mode. Nexus 2000 fabric extenders are not standalone switches; they are managed by a parent Nexus switch. NetworkTigers sells the Nexus 2000 through 9000 families refurbished, used and new, and every unit is tested before it ships so it works when it arrives.

Which Nexus family do I need?
For a new data center fabric, start with the Nexus 9000. To expand or keep spares for an existing network, match the family you already run: Nexus 5000 and 7000 networks are often extended with Nexus 2000 fabric extenders. Check server-facing and uplink speeds, breakout needs, which power supplies and fans are installed, and the airflow (port-side intake or port-side exhaust) stated in the listing; the part number suffix helps confirm it. For Nexus 9000, confirm whether your fabric runs NX-OS or ACI.
Frequently asked questions
Can a Nexus 2000 fabric extender work on its own?
No. A Nexus 2000 is managed by a parent Nexus switch, such as a Nexus 5000, 7000 or 9000, and does not run as a standalone switch. Check that your parent switch supports the fabric extender model before you buy.
