Refurbished Juniper MX10003 Models
The Juniper MX10003 Universal Routing Platform is a compact, ultra-high-performance 3RU router designed for service provider edge, metro aggregation, cloud interconnect, and large enterprise cores. With extremely high 100GbE density, advanced routing scale, EVPN-VXLAN support, and Junos OS reliability, the MX10003 enables multi-terabit infrastructures in a power- and space-efficient form factor. BrightStar Systems stocks used and refurbished MX10003 chassis and line cards so you can deploy carrier-class performance at a fraction of the cost of new hardware.
Every MX10003 we sell is professionally tested, cleaned, and backed by our in-house warranty. Whether you’re expanding a 100G-based edge, building out 5G aggregation, or upgrading an enterprise core, this page is your complete guide to MX10003 hardware.
Juniper MX10003 Overview
The MX10003 provides massive performance in a 3RU chassis with dual line card slots. The platform supports full Junos routing features, MPLS, segment routing, EVPN-VXLAN, rich QoS, advanced timing functions, and high-availability architecture. Supported interface modules include:
JNP10003-LC2103 Line Card: High-density 100GbE line card delivering large-scale 100G aggregation and edge capacity.
JNP-MIC1 Modular Interface Card: Flexible MIC carrier supporting a range of MIC modules for mixed-speed 10G/40G/100G deployments.
This combination gives the MX10003 the flexibility to deliver large-scale 100GbE routing while still supporting access and aggregation use cases. It’s widely deployed by service providers, cloud operators, and large enterprises that require dense 100G capacity and feature-rich routing.
