Overview

Juniper Networks switches

Juniper Networks switches are deployed in UK enterprise campus and datacenter networks. The EX series serves campus access and distribution layers, while the QFX series provides high-performance datacenter switching. We carry out component-level repair on Juniper enterprise and datacenter switches — focusing on power circuitry faults, port-level repairs, stacking issues, and boot circuit diagnostics.
