The 7280DR3K-36S2 is a 400GbE universal spine switch built for large-scale, high-radix datacenter fabrics requiring deep buffer and routing flexibility.
Most enterprise switches ship without transceivers; we quote vendor-matched optics alongside the switch (Cisco-for Catalyst/Nexus, HPE/Aruba-for CX). Third-party MSA-compatible options are also available at lower cost — specify preference in the RFQ.
Yes — our network engineers can pre-stage stacking, VPC pairs, MLAG, EVPN-VXLAN, or fabric extender configurations before shipping, or provide remote commissioning. Add commissioning to your RFQ.
Switch software licensing varies by vendor. Cisco DNA / Cisco DCNM, Aruba CX licensing tiers, NVIDIA Cumulus — we quote the licensing tier matched to your features (BGP-EVPN, telemetry, automation). No surprises at delivery.
