Nodegrid Link SR

Get the right networking, right where you need it with one powerful little box

The Nodegrid Link SR brings flexibility to your network operations. Its powerful components deliver customizable networking wherever you need it, while its compact design can be tucked away to save crucial space. Link server rooms, closets, and branch locations to the internet, and get critical services to keep your network running.

  • Deploy fast using zero touch provisioning and ZPE Cloud
  • Stay in control even during outages with OOB via cellular failover
  • Manage every device thanks to vendor-neutral Nodegrid Manager software
LSR-Angled Nodegrid Link SR

Your link to versatile networking

Deploy the Link SR to provide routing, security, failover, and other services. The Link SR features PoE for versatile power options, and can even serve as a reliable Wi-Fi access point using dual antennas. It features the Nodegrid OS running on powerful x86 architecture, bringing the network function virtualization, out-of-band management, and automation capabilities you rely on.

Deploy your Link anywhere

The Link is the tiniest in the Nodegrid SR family, but it offers many of the same capabilities as its bigger siblings. It allows you to deploy third-party applications, Docker containers, orchestration scripts, and more, for connectivity that’s customized to you.

Does your underground server room lack cellular connectivity?

Deploy the Link SR on the surface to deliver reliable service.

Do you need OOB access to a closet in your faraway branch?

Connect the Link SR and get remote control of your stack.
