A Cisco switch is mainly used to connect different devices such as computers, servers, printers, etc. in a local area network (LAN). It forwards packets from a port to a destination device by learning and filtering the destination address of the packets, thus realizing the communication between different devices in the network.
Cisco switches support a wide range of network protocols and services, and provide multi-level security features, including access control lists (ACLs), virtual LANs (VLANs), and port security, etc. Common series include the Cisco Catalyst series and the Cisco Nexus series, and each series comes with different models and configurations to meet the different requirements of users in terms of performance, number of ports, and features.
We offer a 3-month warranty on used cisco switches purchased from linknewnet. Upon receipt of your order, we will thoroughly test and maintain the equipment prior to shipment to ensure that you receive a virtually new product and experience the best technical support available!
Our used Cisco switch inventory spans the Catalyst 9000 family (9200, 9300, 9400, 9500, 9600), Catalyst 2960/2960-X/2960-XR, Catalyst 3850 and 4500X, and Nexus data center switches such as the N9K-C9372PX-E. Every unit is functionally tested by our engineers before shipment - tell our sales team the exact model and we will confirm stock, grade and configuration.
Yes. Every unit is tested by our professional technical engineers before shipment (testing instructions are available on request) and is covered by a free 3-month warranty, extendable up to 1 year depending on the product. Minor cosmetic scratches are normal on used equipment; confirm the details with our sales team before purchase.
Catalyst 9000 switches run IOS-XE with DNA licensing: DNA Essentials provides the base automation and software management foundation, while DNA Advantage adds SD-Access, TrustSec and richer automation, analytics and telemetry. When buying used, check which DNA subscription is registered to the serial number - subscriptions are transferred through the Cisco Smart Account.
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.
Every unit ships with a free 3-month warranty (extendable on request) plus after-sales support via WhatsApp (+86 18954776148) or email (cs@linknewnet.com).
