Empower your network

At EmxCore we focus on two mayor brands for switches, Juniper and Arista. Juniper and Arista both stand out as industry leaders, providing cutting-edge solutions for seamless networking infrastructures. Looking for other brands? Don’t hesitate to ask! Since we are part of the Circular IT group, we can also offer other brands like Cisco and HP.

In the pursuit of sustainable and cost-effective networking, the refurbished market has emerged as a compelling option, offering reliable performance at a fraction of the cost. We understand the importance of reliable infrastructure, hence we test all our switches not only when they come in but also before we ship them out.

  • What is the difference between a switch and a router?

    Router: Connects multiple networks, operates at Layer 3 (network layer), routes traffic based on IP addresses, used for WAN connectivity and internet access.

    Switch: Connects devices within a single network, operates at Layer 2 (data link layer), forwards traffic based on MAC addresses, used for LAN connectivity and local traffic management.
