QFX5220 Switches

Yes. Refurbished units from Terabit Systems undergo a rigorous 5-step quality assurance and testing process before shipping, and are backed by a 1-year replacement or full refund guarantee. This ensures the same production-grade reliability as new hardware, at significantly reduced cost, making them suitable for spine-leaf and aggregation roles.

QFX switches support VXLAN overlays with EVPN or OVSDB control planes, functioning as either a Layer 2 or Layer 3 gateway. This enables controllerless or SDN-controlled deployments, allowing data centers to build scalable, multi-tenant network fabrics with efficient tunnel encapsulation and decapsulation.

AFI (Air Flow In) switches draw air in through the fan and power supply end and exhaust it through the port panel, ideal when the port side faces the hot aisle. AFO variants reverse this flow. Choosing the correct airflow direction is critical for maintaining proper data center cooling efficiency and hardware longevity.

Yes. Terabit Systems buys used networking equipment from brands including Juniper, Arista, Cisco, and Extreme, offering fair-market value or trade-in credit toward new purchases. This helps offset costs and supports responsible disposition of decommissioned data center assets.

Junos OS on QFX switches is available with a base license, plus optional Premium and Advanced licenses. The Premium license adds BGP, IS-IS, and EVPN-VXLAN capabilities, while the Advanced license unlocks MPLS features including L3 VPN, 6PE, RSVP-TE, and LDP for edge routing deployments.
