Frequently asked questions
Does the NVIDIA Quantum-2 QM9790 InfiniBand NDR Director Switch support our SFP transceivers?
Most enterprise switches ship without transceivers; we quote vendor-matched optics alongside the switch (Cisco-genuine for Catalyst/Nexus, HPE/Aruba-genuine for CX, Juniper-genuine for QFX/EX). Third-party MSA-compatible options are also available at lower cost — specify preference in the RFQ.
Do you provide stacking / VPC / MLAG configuration help?
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.
What software licensing is included?
Switch software licensing varies by vendor. Cisco DNA / Cisco DCNM, Aruba CX licensing tiers, Juniper Premium, NVIDIA Cumulus — we quote the licensing tier matched to your features (BGP-EVPN, telemetry, automation). No surprises at delivery.
Is the warranty global?
Yes — manufacturer hardware warranty is global (return-to-vendor or advance replacement depending on tier). For 24x7 same-day on-site replacement, attach a SmartNet / Foundation Care / J-Care contract during quoting.
