What is the difference between Juniper QFX and EX series switches?

The QFX series is built for data center switching - high-density 40G/100G ports, very low latency and VXLAN/EVPN/MPLS features (e.g., QFX5100, QFX5120, QFX10002). The EX series targets campus and enterprise access/distribution (e.g., EX3400, EX4500).

Are used Juniper switches fully tested before shipping?

Yes. Every Juniper unit is tested by our engineers before shipment - ports, hardware health and boot-up are verified (testing instructions available on request) - and ships with a free 3-month warranty, extendable on request.

Do Junos licenses transfer with used hardware?

Junos OS is licensed per device and in most cases stays with the hardware; some feature licenses may need re-registration. Tell our sales team the exact model before purchase and we will verify what is included.

What after-sales support comes with used Juniper switches?

Every unit includes a free 3-month warranty (extendable) and after-sales support via WhatsApp (+86 18954776148) or email (linknewnet@gmail.com).
