Used Cisco Interfaces & Modules

Cisco's interfaces and modules are an essential part of building network devices, providing network administrators with the flexibility and scalability they need to customise and upgrade for different needs and situations. These interfaces and modules are widely used in Cisco switches, routers, and other network devices to provide users with rich network connectivity and functionality.

Cisco's interfaces are the physical or logical interfaces on network devices that connect to other devices or networks and are versatile, high-performance, and hot-swappable. These interfaces include Ethernet interfaces, serial interfaces, fibre-optic interfaces, and so on, depending on the purpose and configuration of the device.

Cisco's modules are feature-rich and scalable pluggable components. These modules include network interface cards (NICs), security modules, and storage modules ....... These modules, which include network interface cards (NICs), security modules, and storage modules, can be installed to increase the functionality and performance of a device based on user requirements.

Overall, Cisco's interfaces and modules are key components in building network devices that, through their versatility, high performance, and scalability, provide users with a rich set of network connectivity and functionality to support a wide range of network deployments of different sizes and types.

We offer a 3-month warranty on used cisco interfaces and modules 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!

Frequently Asked Questions

What kind of Cisco modules does LinkNewNet sell?

We stock a wide range of used Cisco modules and line cards: Catalyst 9000 network modules (e.g., C9300-NM-8X, C9300-NM-2Q), Catalyst 6800/6500 line cards (C6800-48P-TX-XL, C6800-16P10G), Nexus 7000 fabric modules (N7K-M224XP-23L, N7K-M324FQ-25L), ASA/Firepower security modules and ISR NIM/SM modules (NIM-4-10GE-SFPP, SM-X-4X1G-1X10G).

How do I know a used module is compatible with my switch or router?

Each module is built for a specific chassis or slot type - for example, Catalyst 9300 network modules only fit Catalyst 9300/9300X switches, and Nexus 7000 fabric modules require the matching chassis. Give our sales team your exact platform and slot, and we will confirm compatibility before you buy.

Are used Cisco modules fully tested before shipping?

Yes. Every module is tested by our engineers before shipment - ports, optics and management plane are exercised (testing instructions available on request) - and ships with a free 3-month warranty, extendable on request.

Can I mix used modules with my existing installed base?

In most cases yes - Cisco modules are hardware-level compatible across the same platform family regardless of whether the rest of the chassis is new or used. Confirm the required IOS-XE version and feature support for your specific combination with our sales team.

What after-sales support comes with used Cisco modules?

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