Frequently Asked Questions

Are used Cisco switches and routers fully tested before shipping?

Yes. Every used Cisco unit is tested by our professional technical engineers before shipment, and testing instructions can be provided on request. Units are sold with a free 3-month warranty (extendable up to 1 year depending on the product - contact our sales team). Minor cosmetic scratches are normal on used equipment; confirm the details with our sales team before purchase.

What is the difference between Cisco DNA Essentials and DNA Advantage?

DNA Essentials provides the base automation and software management foundation (including core Cisco DNA Center workflows), while DNA Advantage adds advanced capabilities such as SD-Access, TrustSec, and richer automation, analytics and telemetry. When buying a used Catalyst 9300 or 9500, check which DNA subscription is registered to the serial number - subscriptions are transferred through the Cisco Smart Account.

What does Cisco Smart Net Total Care (SNTC) cover on used equipment?

SNTC combines 24/7 TAC technical support, software updates and advance hardware replacement, available in service levels such as 8x5xNBD, 24x7x4 and 24x7x2. On used gear the contract follows the serial number - our sales team can help you verify contract eligibility before you buy.

Can Catalyst 9200 switches stack with Catalyst 2960-X/XR or share modules with the Catalyst 9300?

No on both counts. Catalyst 9200 cannot be stacked with Catalyst 2960-X/XR (different CPU architecture and platform scaling), and Catalyst 9300 network modules are not compatible with Catalyst 9200 switches.

Do used Cisco products come with a warranty and after-sales support?

Yes - a free 3-month warranty is included on every unit, and extended warranty periods are available on request. Our support team is reachable via WhatsApp (+86 18954776148) or email (linknewnet@gmail.com).
